Learning question: What is the structure and function of the heart?
Homework: AS Human Biology Booklet 2 (Year 12) Learning Package X
To better explain the dynamics of cardiovascular function and control, an analogy has been drawn to the operation of a city water supply. In cities that use a water tower, fresh water is pumped up into the tower from a river or other source. The tower serves as a pressure reservoir for providing water to homes through a largely parallel arrangement of distribution pipes. Local homeowners control their own water usage through faucets, whereas the city maintains water pressure by monitoring the level in the tower. Key analogous points with the cardiovascular system are the heart as the city pump, the aorta as the water tower, arteries as parallel distribution pipes, and arterioles as faucets.
