Cardiovascular System

By Nikita Ganji and Kyla Brown

Overview of the Cardiovascular System

The Cardiovascular system consists of the heart and blood vessels. The main function of this system is to take deoxygenated blood and lead it out of the heart and take in oxygenated blood and distribute it to the rest of your body. This system transports nutrients, oxygen, and blood cells throughout your body.

How your heart works (parts of the organ and functions)

First deoxygenated blood flows in through the right pulmonary arteries into the superior and inferior vena cava. From there the blood goes into the right atrium and flows past the tricuspid valve into the right ventricle. Afterwards it flows through the pulmonary valve into the left pulmonary arteries and leaves the heart to be oxygenated. After the blood becomes oxygenated it flows back into the heart through the left pulmonary veins into the left atrium. From there it goes past the mitral valve into the left ventricle. Afterwards it flows through the aortic valve to the aorta so the oxygenated blood can be distributed throughout the body. The two parts of the heart, one with oxygenated and another with deoxygenated blood, are separated by the septum.
