The cardiovascular system is the body’s main transport system, made up of the heart, blood, and blood vessels (arteries, veins, and capillaries). Its primary function is to circulate oxygen, nutrients, hormones, and essential substances to all body tissues while removing carbon dioxide and metabolic waste. The heart acts as a powerful pump, maintaining continuous blood flow to support normal body functions. This system also helps regulate body temperature, maintain blood pressure, and support immunity. Proper functioning of the cardiovascular system is essential for overall health and survival.
