it supplies the heart and the brain
They supply blood to the body. Arteries supply oxygenated blood throughout the body. Arteries carry oxygenated blood away from the heart to bodily tissues. Veins, on the other hand, carry oxygen deprived blood back to the heart.
The heart uses about 20% of the body's total oxygen supply. It requires a constant supply of oxygen to function properly and sustain the body's energy needs. If the heart does not receive enough oxygen, it can lead to serious health issues such as heart attacks.
The coronary blood supply is the arteries which supply the heart itself; in order for the heart to function it needs a good supply of oxygen just the same as any other organ/muscle. Without the coronary blood supply the heart would not be able to pump blood around the body, a disruption in this blood supply would cause a heart attack.
The heart is responsible for supply of food and oxygen to all the cells in your body. The function is done through blood supply.
Your heart supply food and oxygen to your body. When heart wants to supply more oxygen, it beats at faster rate. Simultaneously, you breath at faster rate to consume more oxygen.
