Cardiovascular/Circulatory System

Your heart, blood, and cells make up the circulatory also known as cardiovascular system.
The cardiovascular system is responsible for a cycle that moves blood from your heart then to every part of your body and then back again. At the middle of the cardiovascular system is your heart. Your heart is a muscle that pumps blood through your body and handles 3 kinds of circulation:Your heart has a whole network of blood vessels that brings nutrients in and removes waste products. This is called coronary circulation. Pulmonary circulation is the flow of blood from the heart to the lungs.
In the lungs your blood drops out CO2(stands for carbon dioxide) for you to breathe out and picks up oxygen for you to breathe in. The oxygen-rich blood heads back to the heart which brings us to systemic circulation. Systemic circulation brings oxygen to all the cells that needed and removes the waste products like the coronary circulation does.
