Now the Olympic flame has left the UK its remaining legacy is to tickle pink a generation, promoting the benefits of physical fitness. What are the benefits to the cardiovascular system of regular exercise - Essay ExampleThis study is a discussion of the main physiological features of the cardiovascular system.The heart, one of the systems major components, has devil ventricles at the bottom chambers of the heart and two atria at the top chambers (Aaronson et al, 2004 p47). The ventricles force the consanguinity into the blood vessels from the heart while the atria drains and forces blood into the ventricles. The heart is divided into two chambers in company to achieve a two-circuit system of circulation. The right side pumps to the lungs while, on the other hand, the left pumps to the other organs of the body. During the cycle of a heartbeat, the right and left atria contract, then the right and left ventricles follow suit, followed by tranquility of the ventricles and atria. During the resting phase for the ventricles and atria, blood fluxs from the relaxed atria to the relaxed ventricles, constituting the diastole. The atria then contract to force out any remaining blood around followed immediately by the ventricle, constituting the systole.To ensure that blood flows in the right direction, the heart has valves that allow blood to motivate in only one direction. The heart valves open and close when the heart relaxes and then contracts, which is caused by the cart difference in the heart, and these valves are aortic, mitral, pulmonary, and tricuspid valves (Aaronson et al, 2004 p50). The one way nature of the valves ensures that blood does not flow back, which avoids mixing of different blood.The heart is comprised of the cardiac muscle, which is a striated and involuntary muscle found on its walls and histological foundations (Aaronson et al, 2004 p52). While smooth muscle is also involuntary, cardiac muscle is more anatomically related to osseous muscle since smooth muscle is not striated. The cardiovascular system is made of an amalgamation of smooth and cardiac cells, with the blood vessels lined by smooth muscle.The circulatory system is
