Arteries are pipe like structure composed of three layers.

Outer layer : tunica externa

Middle layer : tunica media

Inner layer tunica interna

In the atherosclerosis the innermost layer get ruptured first and then initiate it. After rupturing of innermost layer a liquid or semisolid content composed of lipid, fatty acid and cholesterol deposition get started.

The deposition and quantity of plaque increases and blocks the passage of artery. It blocks 50% of arterial passage. When it reaches from 70-90% it either form blockage of artery or form a blood clot.

The earlier stages the symptoms of atherosclerosis does not appears. In the late for extreme stages symptoms appears and causes pain or inflammation.
