Blood circulates through a network of vessels in the body, primarily comprising arteries, veins, and capillaries. Oxygen-rich blood is pumped from the heart through the arteries to the body's tissues, while deoxygenated blood returns to the heart via the veins. The capillaries facilitate the exchange of oxygen, nutrients, and waste products between blood and cells. This continuous cycle, driven by the heart, is essential for maintaining bodily functions.
