The Cardiovascular System

The cardiovascular system also known as the circulatory system contains major parts and organs of the body. This system assists all other parts of the body supplying oxygenated blood from the heart to the other different parts of the body containing nutrients required. This can be done through arteries, veins, and capillaries. Each component of the heart has different functions. Arteries are the ones which have the color red and they carry out the oxygenated blood from the heart to the lungs while veins do the opposite and has blue color. Capillaries, on the other hand, are the supporting structures of the veins and arteries connecting them and collecting the oxygenated blood in and out of the heart. This process is called the carbon dioxide process. It explains why we generally breath in oxygen and carbon dioxide out.
This process works starting either by the superior vena cava or the inferior vena cava meaning the blood either coming from the upper or lower parts of the body then to the right atrium which then is followed by the tricuspid valve then to the right ventricle then to pulmonary valve then to the pulmonary artery. After it goes to the pulmonary artery it goes to the lungs in exchange for oxygen through the carbon dioxide. First before it jumps into the heart through the pulmonary vein then to the left atrium, to the mitral valve, then to the left ventricle which then passes through the aortic valve and the aorta then finally the oxygenated blood will be released through the different parts of the body.
