English: Heart diagram with labels in English. Blue components indicate de-oxygenated blood pathways and red components indicate oxygenated blood pathways. Blue components indicate de-oxygenated blood pathways and red components indicate oxygenated blood pathways.
Diagram of the human heart showing blood oxygenation to the pulmonary and systemic circulation. The heart pumps blood to all parts of the body providing nutrients and oxygen to every cell, and removing waste products. The left heart pumps oxygenated blood returned from the lungs to the rest of the body in the systemic circulation.

Coronary arteries supply oxygenated blood to the heart muscle. Cardiac veins then drain away the blood after it has been deoxygenated. Because the rest of the body, and most especially the brain , needs a steady supply of oxygenated blood that is free of all but the slightest interruptions, the heart is required to function continuously.
Blood flow diagram of the human heart. Blue components indicate de-oxygenated blood pathways and red components indicate oxygenated pathways. The heart functions as a pump and acts as a double pump in the cardiovascular system to provide a continuous circulation of blood throughout the body.
