Circulatory system

The circulatory system includes the heart, blood vessels, and blood. Arteries take blood with oxygen to our organs; veins bring deoxygenated blood to the heart (to be pumped to the lungs to get oxygen). Arteries and veins bring essential nutrients from digestion (such as glucose) to our tissues as well.
