Heart Disease Stent and Angioplasty: A stent is a mess tube used to treat narrow or weak arteries (blood vessels that carry blood away from the heart to other parts of the body). The stent is placed in the artery as part of an Angioplasty procedure. Angioplasty restores blood flow into narrow or blocked arteries. The stent helps to support the inner wall of the artery after the angioplasty. Doctors also place stents in weak arteries to improve blood flow and prevent arteries from bursting.

The heart is the organ that helps supply blood and oxygen to all parts of the body. It is divided by a partition or septum into two halves‚ and the halves are in turn divided into four chambers. The heart is situated within the chest cavity and surrounded by a fluid filled sac called the pericardium. This amazing muscle produces electrical impulses that cause the heart to contract‚ pumping blood throughout the body. The heart and the circulatory system together form the cardiovascular system.

The Artificial Heart The artificial heart is an extra pumping chamber that can pump blood throughout the body. The heart is a muscular pump that maintains oxygen and blood circulation through the lungs and body. Our heart pumps about 2‚000 gallons of blood throughout the day.

During the next phase‚ the two atria are partly separate but there is just one big ventricle. The next phase begins when the two atria are completely separate and the ventricles are just beginning to separate. Finally‚ the ventricles separate completely and the heart is developed. 2.

The heart is one of the most important organs in your body. So what does it do? It’s function is to pump blood to all the other organs. But the heart can not function alone‚ it has other organs and blood vessels helping it. The human heart is a pear shaped and about the size of a human fist. It is made of muscle and there are three different layers. The outer layer is called the epicardium. The middle layer is called the myocardium which is made of muscles that contract. The inner layer is called

The human heart is slightly bigger than the size of ones fist. It is situated at a very safe place which is between the cage bones‚ i.e.‚ in the center of the chest. Usually it is slightly on the left side of the chest but in rare cases‚ it can be found on the right side. Heart is responsible for the blood flow to every single part of the body by constant contraction and relaxation of cardiac muscles. This is the reason why we hear rhythmic beats all the time. Heart pumps the pure blood to the different
