Document Summary
Fluid flows through a pipe only if they are forced to do so. Force is produced by a pump which increases pressure of the liquid at the pump above the pressure of the pipe. The right side of the heart pumps blood into the lungs and back into the heart through the left side (pulmonary circulation) The left side of the heart pumps blood to all other tissues and back into the heart through the right side (systemic circulation) Generating blood pressure: required to force blood through blood vessels. Routing blood: separates pulmonary and systemic circulations ---> ensures oxygen rich blood to tissues. Ensuring one way blood flow: the valves of the heart ensure a one-way flow of blood through the heart and blood vessels. Regulating blood supply: change blood flow to changing metabolic needs of the body (exercise, rest etc) Decreases in size after 65 years of age.
