Our Heart Keeps Us Going

The heart is something that beats in our bodies. Hearts keep our body alive. The faster you run, the faster your heart beats.  There are four different components of blood - red blood cells, white blood cells, liquid and plasma.

Every time a heart beats, the blood circulates around the body. The blood circulates the body, it is called a circulatory system. It pumps blood through tiny tubes that circulate around the body. After the blood is pushed to all parts of the body, it keeps going around the body.

Our heart is important because it keeps us alive. It helps us to circulate our blood inside as it pumps the blood through our veins.
