The circulatory system is a vast network of organs and vessels responsible for the flow of blood, nutrients, hormones, oxygen and other gases to and from cells. Without a circulatory system, the body will not be able to fight disease or maintain a stable internal environment – such as the proper temperature and pH – known as equilibrium: the heart, blood, and blood vessels from the circulation as a whole.
Pulmonary circulation includes, “loop” through the lungs where blood oxygen is filtered; it also contains systemic circulation, which passes through the rest of the body to provide oxygenated blood. The pulmonary circulatory system sends oxygen-depleted blood away from the heart through the pulmonary artery to the lungs and restores oxygenated blood to the heart through the pulmonary veins.
