What does the cardiovascular organ system do?

Answer 1

Good question! Not many people know or understand this. The Cardiovascular System deals with your legs, butt, thighs, abbs, and stomach muscles. It firms everything and makes you look really great.

Answer 2

Short answer- it's responsible for getting oxygenated blood to your entire body, removing the de-oxygenated blood and its waste products for re-oxygenification. It stops your extremities dying and dropping off.

Long answer-

Cardio means heart (or suggests it at least) and vascular is the system of veins. When we breathe in, oxygen is passed into our blood through the capillaries in our lungs. From here the oxygenated blood needs to get to the rest of the body and that's where the cardiovascular system comes in.

The oxegenated blood flows from the lungs via the pulmonary veins to the heart, specifically the left ventricle, which pumps it out through the aorta with enormous pressure into the arteries and eventually the capillaries (the pulse is this pumping of blood out of the heart to the body).

The de-oxygenated blood flows out of the capillaries, into the veins and back to the heart, specifically to the right ventricle. The heart pumps the de-oxygenated blood back into the lungs via the pulmonary artery and that's the cardiac cycle.

It all occurs simultaneously and the mitral & aortic valves stop the de-oxygenated blood in the right ventricle from mixing with the freshly oxygenated blood in the right one.
