The word '-athero' means paste and '-stenosis' means harden. So, atherosclerosis is the hardening of deposits formed inside the blood vessels, gradually building up to obstruct the blood flow in the vessel, and eventually, restricting the blood flow completely.
In a healthy person, the innermost lining of the arteries is smooth and elastic. But, in persons with risk, the layer is damaged. This attracts the bad cholesterol to build up in the artery wall, forming plaques. The white blood cells (WBC) in the blood react to this by invading the area to ingest the LDL cholesterol.
