The system that transports nutrients, water, and oxygen to every living cell in the body is the circulatory system. It consists of the heart, blood vessels, and blood, which work together to ensure that essential substances are delivered to cells while removing waste products. The heart pumps oxygenated blood from the lungs through the arteries, while veins return deoxygenated blood back to the heart for reoxygenation. This continuous circulation is vital for maintaining cellular health and overall bodily function.
