The heart is the one major oran that keeps the body functioning. Without the heart, we would simply not be able to function. With the help of the lungs, the heart is the major organ that provides our bodies with life giving oxygen and takes away carbon dioxide that is a poison in our body. Without the oxygen the blood provides for the body through reseperation, the brain will not be able to function as the brain needs oxygen to survive. We need our brains to survive, and without them we will become vegetables.
Four Chambers:
The heart has four chambers: the left and right ventricle and also the left and right atrium. this is where the blood passes through and take the oxygen poor/rich blood through the body. First the left side with the oxygen rich blood and then to the right that takes the oxygen poor blood out. This effectively keeps us moving and alive.
In betweem chambers is a wall of muscel called the septum. and to cut the atrium and ventricle on each side is a valve. THe tricuspid and the mitral valve.
Heart Disease:
Heart disease is now the number one killer in america. NExt to cancer it is what most people have. THere are many things that can be wrong with the heart. Such as a hole in the heart which must be surgeically fixed immediatly. A Murmer which you are born with and can depend on severity. From just a small hitch, too what seems like a harsh gasp in the heart.
Heart disease can happen in two ways. THe heart can litterialy rot out due to bad diet and poor exercise. Another way for it too happen is plaque to build up within the arteries. TO fix that they insert a wire of some sorts through a artery in your leg and thread it to your heart to scrap away some of the plaque. another way is to do a by pass surgery. Where you take a part of a artery and use it to by pass a blockage in the heart bu going over it with the good piece of artery.
