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.
