Document Summary
A series of blood vessels that start off big and to exchange nutrients and oxygen for waste and oxygen poor blood to the kidneys, and transfer good blood and nutrients to the heart and lungs. Heart fills passively and pumps blood through a muscular action that is a result of both electrical and muscular action. Work is done within and outside the capillaries: the heart. There a number of different structures in the heart that need to be intact: A series of valves keeps blood flowing in one direction to prevent de-oxygenated blood to flow back out into the body: the blood needs oxygen and gets it from the lungs. Systemic circulation = left heart function (out in the body) Heart should beat about 60-75 times per minute on average (athletes have a slower rate then those who are not athletic: heart rates higher than that: Tachycardia: tries to send out more blood than nessecary.
