Document Summary

The heart performs sensory and endocrine functions that help regulate cardiovascular variables such as blood volume and pressure. The blood vessels are not just conduits for blood, but are also important sensory and effector organs that regulate blood pressure and the distribution of blood to various parts of the body. The blood also transports hormones, serving as communications link acting in conjunction with the nervous system. Regulation of the cardiovascular system involves interactions with several other organ systems, including the nervous system, the endocrine system, and the kidneys. A muscular organ whose function is to generate the force that propels blood through the blood vessels. The heart can be functionally separated into left and right halves. The atria and ventricles on either side are separated by a wall called the septum that prevents blood in the left heart from mixing with blood in the right heart.
