Your heart acts as a pump to push blood through your blood vessels and to all the organs, muscles and nerves in your body. Blood carries oxygen, which is required by your organs to function; without oxygen supply your organs would be unable to function.

There are four valves that are responsible for ensuring the blood flows in the correct direction.

Blood supply to the heart muscle
The heart is an important organ; hence it requires blood supply to function properly. Blood is supplied to the heart via coronary arteries. If these coronary arteries become blocked, blood supply can be reduced and limit the amount of oxygen the heart receives, which can put you at risk of a heart attack.
