It has four chambers and blood travels around the body in this order:
Body>Right Atrium>Right Ventricle>Lungs>Left Atrium>Left Ventricle>Body.
The heart contributes to circulation and oxygenating blood.
It is the strongest muscle in the body and is made of cardiac muscle.
The heart beats involuntarily. (of course).

I know quite a bit about it, but your grammar is so bad in your question that I am unsure what you need. I'll give you an overview....
The human heart has four chambers. They are the right atrium, left atrium, right ventricle, and left ventricle. Each of these are separated by special valves that control and direct blood flow. The heart is very muscular and works as a pump for the circulatory system.
If you need more than that, post a new question. Please use spell check next time and take your time writing your thoughts down, OK?

there is so many things to learn about the human heart. You can't just ask about the human heart without expecting a page long story. What do you need to know? About blood flow? Chambers? Valves?

it pumps blood
average beat is around 70 to 80 a minute
any faster than that means the person isnt the healthiest. athletes usually have like 60 a minute.
when heart cells die, it hearts
heart cells doenst reprouces very little, so when u have a heart attack, u heart gets weaker.

What exactly do you want to know? It pumps oxygenated blood from the lungs to the rest of the body and carries deoxygenated blood from the body to the lungs. Hope that helps.

Whatever you do, don't rely on anything on Wikipedia. It's the outlet for the ignorant. Whatever is on there was "contributed" by whatever idiot got there first...
NEVER rely on Wikipedia. ALWAYS find a confirming source with some credibility.

Isn't it the strongest muscle in the human body? Well it does circulate you blood through your body carrying oxygen to your cells.

i know that the red vein is actually green. but it punps blood to and from the heart. the blue vein pumps oxygen to and from the heart. to keep your heart strong you need to excersise and eat fruits and vegetables, forget the soda!!
