An exclusion is a policy provision that eliminates coverage for some type of risk. Exclusions narrow the scope of coverage provided by the insuring agreement. In many insurance policies, the insuring agreement is very broad. Insurers utilize exclusions to carve away coverage for risks they are unwilling to insure.
The blood enters the left atrium and is pumped into the left ventricle. From the left ventricle, the oxygen-rich blood is pumped to the rest of your body through the aorta. The aorta is the main artery that carries oxygen-rich blood to your body. Like all of your organs, your heart needs oxygen-rich blood.rom the left ventricle, the oxygen-rich blood is pumped to the rest of your body through the aorta.

The heart is constructed of a special kind of muscle called the myocardium or cardiac muscle, and is enclosed in a double-layered, membranous sac known as the pericardium. A wall of muscle, the septum, divides the heart into two cavities.The left cavity pumps blood throughout the body, while the right cavity pumps blood only through the lungs. Each cavity is in turn divided into two chambers, the upper ones called atria, the lower ones ventricles.Venous blood from the body, containing large amounts of carbon dioxide, returns to the right atrium.he left cavity pumps blood throughout the body, while the right cavity pumps blood only through the lungs.
