Heart
A heart is a hollow muscular organ that pumps blood through your body. If we do not have a heart we will not be alive.
Our heart does not shape like a heart , Our heart looks like this.
Your heart pumps blood around your body to all the organs, muscles, and other parts of the body . Most heart attack are caused by a blood clot that can block coronary arteries (this word is part of the heart - left Coronary Artery and right Coronary Arteries).
can not see your heart but you know it is their because it is pumping and it keeps you alive.
