Explanation:
Detailed explanation-1: -The heart is a hollow muscular organ about the size of a closed fist. It’s in the centre of your chest, behind the breastbone. Each heartbeat sends blood that’s rich in oxygen and nutrients to all parts of your body.
Detailed explanation-2: -Looking at the outside of the heart, you can see that the heart is made of muscle. The strong muscular walls contract (squeeze), pumping blood to the rest of the body. On the surface of the heart, there are coronary arteries, which supply oxygen-rich blood to the heart muscle itself.
