Document Summary

Module 8 - circulatory system 1: the heart contents. The four principal functions of the cardiovascular system: It transports oxygen and nutrients to all cells of the body: transports carbon dioxide and waste from the cells. It transports and distributes hormones and other substances within the body. Anatomy - the heart: y consists of two side-by-side pumps: the right atrium and ventricle - which pumps blood to lungs, the left atrium and ventricle - which pumps blood to the rest of the body. Superior vena cava: delivers blood to the heart from the head and upper limbs. Pulmonary artery: blood leaving the right ventricle travels to the lungs through this artery. Aorta: blood leaving the left ventricle travels through the aorta and is distributed to the entire body. Left atrium: receives blood that has come from the lungs y this blood is rich in oxygen and low in carbon dioxide y.
