THE CIRCULATORY SYSTEM
The Pulmonary Vein
The pulmonary vein sends the oxygen- rich blood back to the heart...
The Circulatory System functions in the delivery of oxygen, nutrition molecules, hormones, the removal of carbon dioxide, ammonia, and other meta- bolic wastes.
The circulatory system is a body-wide network of blood, blood vessels, and lymph. Powered by the heart, it is the body's distribution system to organs with oxygen, hormones, and essential nutrients that help it function properly.
