The human circulatory system, also known as the cardiovascular system, is a vast network that transports blood to all parts of the body. It consists of the heart, blood vessels, and blood. The heart, a four-chambered muscular organ, pumps oxygenated blood via arteries to the body’s cells and receives deoxygenated blood through veins. This system is essential for the transportation of nutrients, oxygen, and hormones to cells throughout the body, and for the removal of metabolic waste.
