The circulatory system is responsible for regulating blood circulation throughout the entire body, ensuring that waste products, nutrients, hormones, and oxygen are efficiently transported to and from cells and tissues. This system is made up of the heart, blood vessels (including veins, arteries, and capillaries), and blood. Blood vessels act as pathways, directing blood to all parts of the body, while the heart powers the circulation by pumping blood through these vessels. The proper functioning of the circulatory system is vital for the health of all organs and tissues, and any disruption can lead to significant health problems.
