When the arteries supplying the periphery of the body such as the legs become narrowed or blocked, causing pain and/or tissue death.
Transport system of the body made up of the heart, the blood vessels and the blood. Also known as the circulatory system
When a fatty deposit or plaque builds up on the wall of an artery and reduces the blood flow through it.
A heart attack when the heart stops beating completely.
The result of a lack of blood to the heart muscle due to atherosclerosis in the coronary arteries. It can be fatal.

The cardiovascular system – the heart, the blood vessels and the blood – is vital to maintaining life. Things can go wrong at all levels, from the constituents of the blood to the pipes that carry it around the body and the pump itself.
The human cardiovascular system
Cardiovascular disease describes a variety of conditions that affect the flow of blood to the heart. Many of them are linked to an initial problem called atherosclerosis. In atherosclerosis the lining of the arteries becomes coated with fatty substances referred to as plaque or atheroma. Atherosclerosis leads to narrowing and hardening of the arteries. It is linked to high blood cholesterol levels, obesity, lack of exercise and smoking. Atherosclerosis can lead to a number of different problems with the cardiovascular system.
There are other types of heart problems as well. These include:
