Every heart beat is the sound of the heart pumping to push blood around body. The heart pumps oxygen -rich blood through tiny tubes that lead to every part of the body. Because it is about blood circulating in the body, the systems called the circulatory system.
Our heart beats faster when we run and jog because our body needs more oxygen as it pumps blood around the body. When we get tired of doing exercise and playing, the heart beats 60 to 80 times
a minute so you need to relax yourself so that your heart can relax too.
After blood it pushed to all parts of the body,
it is then pushed back again. It takes less than a
minute for blood to go all round body. Blood has four main components red blood cells, white blood cells, liquid and plasma.
When our heart stops beating we die. We should
look after our body by eating healthy food, by getting plenty of sleep and doing exercises. In this
way, we know that we try our very best to become
healthy people with healthy heart.
