Blood and circulatory system quizlet
What is the main purpose of the circulatory system?
The function of the circulatory system is to pump blood so that different nutrients and oxygen reach the interior of the cells of each organ. The circulatory system regulates body temperature and water balance. It transports defense molecules , hormones and communication (carrying information to the brain , for example).
What are the two systems of the circulatory system?
Our bodies actually have two circulatory systems: The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation (the system we usually think of as our circulatory system) sends blood from the heart to all the other parts of our bodies and back again.
What is the circulatory system?

system delivers oxygen and nutrients to the body tissues and carries away wastes such as carbon dioxide via blood. The heart pumps blood throughout the body in blood vessels. Blood flow requires both the pumping action of the heart and changes in blood pressure. If the cardiovascular system cannot perform its functions, wastes build up in tissues.
