The function of the cardiovascular system is to circulate blood through a large network of vessels that run throughout the body. This provides each cell with nutrients and oxygen and also helps to dispose of waste products which is a main purpose of the cardiovascular system.
Blood rich with oxygen leaves the heart via the arteries and also helps to deliver nutrients and oxygen to body cells. The cells use the oxygen to produce energy and in exchange the cells release waste products such as water and carbon dioxide. Veins then carry these waste products, which are carried in oxygen poor blood, back to the heart. The heart then pumps this blood to the lungs where carbon dioxide is both unloaded and exhaled and fresh oxygen is inhaled. The cycle begins again once the oxygen rich blood is carried back to the heart.
The cardiovascular system as well as circulating oxygen around the body also helps to regulate our body temperature. Thermoregulation is the process that ensures our body temperature remains constant. Our body temperature can be affected by different environments we may be in like the weather, participation in physical activity and also if you have an illness. It is essential that our body temperature stays moderately constant because of the fact that vast changes in the body’s temperature can affect the body’s ability to function properly. In order to keep our body temperature as constant as we can, blood vessels vasodilate or widen to
