The heart is the muscular organ about the size of our fist located just behind and its notch bit entended towards the left of the sternum. The heart pumps oxygenated blood to all parts of the body. It received deoxygenated blood and that carried the waste products from the body, pumps to the lungs for oxygenation. It also maintains the blood pressure in the body. The heart comprises four heart chambers, valves, blood vessels and muscular walls.
The four-chamber in the heart is;
- Left atrium
- Right atrium
- Left ventricle
- Right ventricle
