The gallbladder concentrates and stores bile as a pear-shaped sac which it can release to help digestion after a fatty meal.
Cooling down exercises are performed at the end of an exercise session. The objective of cooling down is to bring the bodyâ€™s physiological processes to normal in a gradual manner. An abrupt end to exercise can lead to a lactic acid buildup, cooling down helps in the removal of lactic acid from muscles. It also helps to prevent the pooling of blood in peripheral veins which are in a dilated state to accommodate greater amount of oxygenated blood for the muscle being exercised. Cooling down can take anywhere between five to ten minutes and can involve stretching, brisk to slow walking, drinking water, and focused breathing. Warming down is a synonym for cooling down.
