Energy From the sun

The sun is where we get our energy. The energy gets smaller every time something eats. 

I didn't know much about the subject before we started. Now I know that eating plants and meat is the better diet chose because you get a more balanced diet. We have a process which goes plant ,animal ,us. This is because the plant is where the energy goes then the cow or another animal eats that then we eat the cow or the plant as simple as that. So that is some of what I learned.
I liked this because I got to learn about how food is really needed by us humans. I love how we got to see the website on it it really help me understand this subject.I thought it was weird how the sun only gives half a billionth of sun energy to the earth . I thought there was more sun energy. This is why I liked it so much.

Weekly blog on Photosynthesis

Summary : Photosynthesis is why plant grow . Photosynthesis is what make us alive to day.

Question: ( How much did I know before we started. What do you now know about the topic that you did not know before?) Before we started I did not know how the true process worked.There are more materials needed than I thought . The process is how we are alive today . How is this you may ask and how is because The sun and other materials power plants . Then animals eat plants . Than we eat plants and animals.

Question: ( What is particularly satisfying about this weeks work )  I was satisfied the most when I learned about the real story on photosynthesis . Then learned about how the life cycle really starts with plants. Then we learned a little about how lot of animals live off of fruit.

9/26 Organelle Trail

Organelle Trail

I learned that cell parts work together all the time. I learned about the vacuole and how it stores food and water in thee plant.
I didn't know anything about the topic in the beginning. I now know more about me and how I work. I learned the most about the vacuole and how it keeps the plant alive by storing food and water and keeping the structure of the plant. I am full of cells like blood cells for example and I could not survive without them. Organelles are cells and I am made of cells.

Nervous System

                                                          Nervous System

Function : The function of your nervous system is to send signals to your body. It tells your body where to move. For example me typing this sentence is all done by signals from the brain.

Organs: The organs are the brain which send the signal of what to do. Then there is the spinal cord which transfers the signals to the body. The spinal cord is protected by the vertebrae. Then last but not least there is the nerves which keep the brain on the body. That's the basic idea of them all. Let's go into a little more depth. The brain in the power point for all body motion. The brain tells your legs to move your hands to type and your arms to move. The brain is like a coder. The coder tells the robot ( out body) what to do. Without the code the human could not move or function. Next the nerves. Nerves are how these messages get to all parts of the body.  Your nerves are head to toe so you can have the full range of movement we require. Now last of all the spinal cord. The spiral cord is like the hub for signals. All the nerves connect to it and this is where all signals get sent out. Thats why if your spinal cord gets injured permanently you get paralyzed. That entire part of the hub gets shut down and is unable to get those messages.

Interaction with other systems: The nervous system works with the skeletal system. The skeletal provides protection to the spinal cord. It also proved protection to the brain. I feel that without the skeletal system us as humans would die very fast. Think just one fall on the spinal cord and bam your paralyzed for life. The skeletal system really provides for the nervous system and we could not function without it.

Analogy:
Your spinal cord is like a train station. You see your brain sends in the " trains" holding the action your body must do. Then the spinal cord is the station where it stops of. The spinal cord has access to the location these signals need to go to. Soon the signals or "passengers" on the "train"  so off to there final destination. The nerves. Just like a real train station. It takes you just where you need.

Structure and Function:
The spinal cord is a vital part of this system. Now you can learn more about it. The place and shape of the spinal cord is interesting, It is very long and is the size of your entire torso length wise. It has its benefits though. It has to be very long because it must be able to reach the entire body. We need to nerves to be able to reach top and bottom of the body. It also has hundreds of branches to it. These branches are used to transport the signals the the right place in the body. Now the size of the spinal cord is important. The spinal cord cant just be any size it wants. It works with the vertebrae. The vertebrae is there to protect the spinal cord but changing the size of just one would really hurt your body. All these work together in perfect ( or imperfect) harmony to make it so I can move and write and jump and around. Thanks Nervous system!
                                                   

Urinary system

                                                 Urinary System

Function : The Urinary System is used to get waste out of your body.

Organs: The urinary system starts of with the kidneys. Kidneys filter through blood to remove waste within them. Once the unwanted is taken from the blood cells it goes to the next step. This waste is urine. The urine now moves down to the ureters. The ureters are a pathway for the kidneys to the bladder. The bladder is where your urine is stored. Once the cycle of cleaning cells is complete and the bladder is completely full of liquid. That is when you have to pee.

Interactions With other systems:  The urinary system works with two systems. It works with the digestive system because digestive gives nutrient to the cells that would soon turn to waste. They it works with he circulatory system because circulation is what makes the energy get all used up.


 Analogy: Your kidneys are like a shower. A showers purpose is to get the dirty and grim of your body but of course not was away yous skin. The kidney does the same. It takes out the " grim" from the cell. The kidneys is how the cells stay functional and don't get full of things they don't even need. Just like us if we don't shower and take of the unnecessary dirt we will get sick and it will just fill us up.                


Structure and Function: The bladder is put where it is for many reasons. It shape is for a reason. Even its size matters. Lets see why. The bladders location is at the bottom of your torso. This is because you legs have a long range of motion so they of course can move out o the way of where your bladder deposits. Its also there because  it needs to be close enough to the ground where it wont get you dirty  and just go where you want it too. The shape of the bladder. The bladder is kinda shaped a short vase. This is so it can do its full job and hold as much water as possible within its small space. This is also why the bladder is more like a bag then anything else. It main goal  is to be able to hold urine. Now the size of the bladder is a little strange. The bladder is not very big yet it holds 2 liters of waste. The real question is why not any bigger? Its main goal is to hold urine. You see this would be bad for your bladder. Do you remember why the cells wanted to get rid of the waste. Its because it was unnecessary and just took up space. This just shows that with holding the waste in the bladder for a long time the bladder would become less of an organ and more of a container. The bladder must keep moving and not be an ocean for the body. That is also why the bladder is not made of bone because it needs to move not just hold the urine.




                                               

Skeletal system

                             Skeletal system

Function : The skeletal system is a mean of support for the body. You can think of it as the trunk and branches of a tree. It supports and keeps it all upright. It also protect vital organs such as the heart, brain, lungs etc. Another vital thing it does is produce blood. Blood cells are made in the bone marrow.

Organs : The bones are the main and only organ of the skeletal system. It also includes cartilage,tendons, and ligaments.  All of these have the same function. They make support for the body. Bones keep you upright and protect your organs. Cartilage is a more flexible form of protection but it  is located at the nose and the ear. Then tendons you can think of as a tape between bones and muscles it keeps it connected. Then of course your ligament that connects your joints. The first joint is the elbow joint is a hinge joint that connects the humerus, ulna, and radius of your arm.   Then there is the Hip joint that is a ball and socket joint.  It connects the pelvis to the femur. The last joint is the vertebral column this allows your torso to move from side to side.

Interaction with other organs:
The skeletal works very closely with the muscular system. Literally the muscles surround the bones perimeter. Muscles allow your bones to be able to be used at a full motion. It makes it so you don't just have sticks that hold you in place but let you move and articulate your body. Without one another they would just be a nuisance to the bodies function.

Analogy: The skeletal system is like the outside of a
dream catcher. All the strings work together like the different organs yet they would just be a pile of string (organs) if they did not have the frame to keep them in place. The frame of the dream catchers outside is what keeps everything in its place just like your bones do for your body.


Structure and Function: The femur is  the bodies largest bone. It is places at the thighs. The femurs job is to hold the weight of the top of your body and also to be a connecting point to your calf.  The femur looks like any other bone it is just a huge version of it.  It has to hold most of your organs and other bones and everything else weight wise.  Most organs are places above the waist so you need something strong to support that. Now its size makes it easier for it to support the weight it cant be thin or it would snap under pressure yet it cant be too thick or it would be heavy for anything below it.  Its shape is just the standard shape for most bones but it is a single bone on each side so that does mean it could be easier to break it. That is why its thick enough to not brake easily or that would be big painful trouble for us.

Muscular System

                                                            Muscular system

Function:The muscular system  moves you body  around like when you walk or talk.

Organs:  The only organs in the muscular system is your muscles. Hence the name muscular system. Now what do they do and why is there a system dedicated to them.The muscles are what allows your body to move. For example when i'm typing this sentence i'm using the muscles in my hand to curl the fingers and extend my reach. With my muscles I couldn't even begin to do that.

Interactions With other Systems:

The muscular system works very closely with the skeletal system. Muscles actual shape around your bones  allowing the full range of movement. They look different and they are shaped around the bone they are attached too. Without one another both of these systems would be useless. The skeletal system would just be like sticks within your body. A really hassle for use. Then the muscular system would just be a useless pile of muscular tissue. They need each other.

Analogy:

Your muscles are like oxen. Oxen have been used through history to push and pull heavy objects. Your muscles also have to same job. Muscles are used to move things around such as items or even parts of your body. Oxen do this job to perfection just like your muscles do.

Structure and Function:

Your muscles all have many functions. They do somehow manage to have one cause together as a whole. They are shaped in many ways to fit the shape of the bone it's around. The shape of the muscle is very straight. It is like hairs. They are all lined up yet the size of the strand go in and out like a wave. The length of an individual stand can be different depending on where it is. Think the muscles in your hand is shorter than next to your femur. Next the placement of your muscles. Well you know how your bones are all over your body. Well think of the muscles as covering every surface with bones. They are pretty much everywhere. Now how does this affect the function. All of this makes it so you can move anywhere and everywhere with out this range of motion we could not be successful. I'm glad that we have this.









                                          

Circulatory System

Circulatory System

Function : The Circulatory system get oxygen and nutrient  to all your body. Your heart pumps out oxygenated blood and takes in  deoxygenated blood and oxygenates it. The lungs take in the oxygen and gets rid of the carbon dioxide. The veins transfer the blood back and forth.

Organs : The organs include the heart and veins. The heart in deoxygenated blood and using the oxygen it gets from the respiratory system to oxygenate the blood cells for the rest of the body to use. Then you got  your veins. They are how your blood circulates through the body.  Now why is red blood cells so important. They are how oxygen and carbon dioxide moves through your body.  We all know that oxygen is extremely important to the body. Without it your cells would all die.

Interactions with other systems: The circulatory systems works very closely with the respiratory system. The respiratory system is what provides oxygen for your body. Without that the heart would be completely useless. All the heart would be is a freeway of dead cells.

Analogy: The heart is like a car wash. The heart is like a car wash because it takes in the  deoxygenated blood cells. They can be represented as a dirty csr. Then the deoxygenated cell goes through the hearts car wash. Once it makes its way through it become more oxygenated (clean). Once it makes its way it is fully oxygenated for the body to use or you as the car owner to show off.


 Structure and Function:  The veins in your body are special for a reason. Your veins placement is well everywhere. The veins go across your entire body for a purpose. They need to be  able to oxygenate every place so they have to have roads to reach it. Then the size of your veins. Your veins are quite small for a reason first of all because the cells aren't very big at all so there is no need for lots of space. there are some hidden reasons though. First of all if they were huge that would mean other that the other organ systems would have to be smaller and that would make it so they would function completely different. They also could be easily hit if  they were so big. If that happened you would eventually bleed out. Then of course our shape is because the cells are well round so a round tube would mean no damage will happen to the cells easily in there. This all adds to it huge function of effectively getting oxygen through your entire body.

Digestive System

                                                    



                                                        Digestive System

                                                      

Function:  It is a system where it breaks down your food and bring nutrients to the rest of your body. It transforms

Organs: Mouth, Esophagus, Stomach,Small intestine and Large intestine.  It is a chain of organs that is used to convert food into molecules that go into your bloodstream and of course fuels the body. It starts with the mouth. The mouth of course makes your food small enough to fit down the esophagus. It also makes the small intestine and the large intestines job easier. Now the esophagus. The esophagus is just a pathway for all this grinned up food to go down. It also makes sure that the food goes down the right tube.  Once it goes down the esophagus it goes to the stomach. Your stomach has acids that breaks down the solid foods into a molecules form. This way they can be used in the next step of the process. The small intestine is where most of your food is absorbed. 90% of whats in your food gets taken in this process. So basically the small intestine gets the minerals and nutrients that's in your food.Your large intestine takes in the 10% left from the small intestine. It collect the water and the useless materials. This is where the digestive system ended and starts to work with the urinary system.

System Interactions: The digestive systems works closely with the Urinary system. The one organ that makes this possible is the large intestine. It organizes the waste and water into the body. It puts the pieces it does not need or use away into the urinary system so it can be taken out of the body. If something is useless it is taken away. That's why we produce waste. Without one another they would fail.

Analogy: 

Your digestive system is like worms. Worms jobs are the sort what it eats and turn it into something for them to survive then they just waste the rest. There job is just like our digestive system yet they are always doing it. How you ever wonder where soil comes from. That is what a worm does to compost after it went through its digestive system. They are a perfect example of digestion because it is one of their main goals in life.

Structure and Function:

The mouth. The shape of the mouth is as if you have an apple and that is about the size and general shape. Your mouth is about 45-50 mm wide.  The shape of your mouth is and oval mosty. This is why even if you have a huge mouthful of food you still have your cheeks which as like pockets of either to put food on either side of for you to breath. It is probably designed like this for all us human who think stuffing our faces with marshmallows is a good idea. The placement of your mouth is very important. The placement of your mouth is easily accessible and is not straining to reach with the range of motion that you have i n your arms. It also is always visible so that means you can easy access it. Now why is eating so important? The mouth is literally designed for taking it so what's the big deal? Your mouth is the starting point to of course the digestive system. Without this system your cells would get too tired to function meaning you would not survive. You can only last 30 days without completely shutting down. The mouth is designed for the mass consumption yet also for your safety.

Respritory Sysetm

                                                      Respiratory system 
                                           
      
Function: The respiratory system get the oxygen in your body and get carbon dioxide out. It works with the
circulatory system.

Organs: The organs are the lungs,trachea, mouth ,nose , and diaphragm.They all work together on getting the oxygen to the whole body. You see the nose and mouth have to same purpose. They get the oxygen to your trachea. What does the trachea do. The trachea connect the mouth and the nose to the lungs. Then the lungs the key point leads that oxygen to the heart. The the heart fills the lungs with carbon dioxide. Soon enough the diaphragm kicks in and it moves that air out. This is how this system works together in harmony.

Interaction with other systems: The respiratory system works closely with the circulatory system. The circulatory system needs the respiratory systems oxygen to function at all. Then the respiratory system need the carbon carbon dioxide to breath out and repeat the cycle.

Analogy: The trachea is like a water pipe. It is the perfect path way to connect to source. For a water pipe that would be water and for the trachea that would be the lungs gas. They both transport for the source it proves for.


Structure and Function: The diaphragm is special to its shape placement and size. Lets see why. First of all its size. The size of the diaphragm is just fit to base of the lungs. It cant be any bigger or smaller because that would defeat its purpose. Next the placement. This makes us think what is its job. Well the diaphragms job is to to expand and decrease the size of the lungs. So its placement must be near the lung to work. Then last the shape of it. Then last but not least the shape. The shape of the diaphragm is complete shaped around the base of the lung. It is so close it is like a mold of it.  All of this together does make  the working diaphragm and great diaphragm.

Sienna's Circulatory System

The heart is a key organ in the circulatory system that produces oxygenated blood and gets rid of the non-oxygenated blood. The heart is a muscle about as big a fist. It has a huge job because it is always working, but you never have to think about it. Its main function is to move blood through the body. Your blood carries fuel, energy from your food, and oxygen. It also carries your bodies waste away too. Veins are connected to the heart. The veins carry the blood to all of the body.

Before class today,  I did not know very much about the circulatory system. After the lesson, I learned that your heart has a specific flow. Your oxygenated blood flows out of your lungs to the left atrium. Then it flows to the left ventricle and travels through the veins to all parts of your body. Next, the unoxygenated blood goes to your right atrium and flows down into the right ventricle to the lungs through the pulmonary artery.  This is the cycle of your blood.

It is especially satisfying that we get to learn more about our bodies. The circulatory system is very intriguing because of the way it flows and how much it does for our bodies. I learned that the blood leaving your heart needs to be oxygenated by your lungs at all times. It then goes to the other parts of your body giving oxygen to your muscles and organs.

If I were to give myself a graded give myself a 9 out of 10. I think that I paid attention in class to the video and looked at the rubric for this blog. I followed the directions to make sure that I had all of the parts of the blog and a good summary too. I think I can improve on my blogs as I get my comfortable with the the format.

I would like to improve upon memorizing the names of the different parts of the circulatory system. I love science and I want to remember what you teach me. Maybe one day I'll decide to to be a science teacher or a scientist too. This is my favorite subject.
