Does the circulatory system deliver oxygen to cells?

Yes, the circulatory system, also known as the cardiovascular system, is responsible for delivering oxygen to cells throughout the body. The circulatory system consists of the heart, blood vessels, and blood. The heart pumps oxygenated blood from the lungs to the body's tissues through arteries, and deoxygenated blood is returned to the lungs through veins. Within the capillaries, the smallest blood vessels, oxygen and carbon dioxide are exchanged between the blood and the surrounding tissues. Therefore, the circulatory system plays a crucial role in delivering oxygen to cells and removing waste products like carbon dioxide from the body.
