What are the major organs of the circular system?
The three major organs of the circulatory system are: 1) The Heart: it pumps blood throughout the body. 2) The Brain: It tells the heart when to pump and how fast to pump. The Brain is what tells the heart to speed up during exercise, and to slow down during rest. 3) The Lungs: The lungs bring in air, and the blood goes through the lungs to pick up the oxygen and bring it throughout the rest of the body as the heart pumps.
