How Our Heart Works

5 years ago

So our heart is the main blood supplier to our entire body. It pumps blood that is oxygenated to the muscles that enable us to move, and the oxygen in the blood is used up by these muscles. However when we do not exercise on a regular basis, our heart muscles begin to weaken, and it gets harder for the heart to pump blood to the rest of our body. This results in fatigue from simple activities like climbing stairs! So exercise people!!
