The Heart and Blood

In class 9 we have been learning about the heart and all it's important jobs, we will be telling you about the heart and the blood. We hope you enjoy our post.

Jobs that the heart does:

The heart circles the blood around the body and that gives us oxygen to all parts of our bodies. When this happens valves in our arteries open and shut to let the blood cells through. The heart is one of the main organs in the body. If we didn't have a heart we would not live.

The heart has many tubes pointing outwards into the different parts of our body and which are the tubes that the blood cells go through. In a minute the heart pumps about 60-70 times in a average human to keep us alive.

Jobs that blood does:
The blood runs through all parts of our body transporting oxygen. It also keeps our heart pumping and our heart makes the blood run through so it's like they are partners. without blood our brain wouldn't work to make us intelligent enough. Blood cells also keep us healthy by fighting infections and healing us when we get cut.
