I learned that the heart is one of my muscle and it is different then other muscle , it can send blood around our body and the blood can provides oxygen to our body and it also can carry some dirty things away. And I also learned that heart will fill lot of blood and squirt out the blood, so our blood can around our body , and our heart do it all day all night so heart is really a important muscle.
