<s>[INST] What is atherosclerosis? [/INST] Arteries are blood vessels that supply oxygenated blood from heart to different parts of body
Arteries further divide into capillaries that reach out to each and every cell of the bodyHere, nutrients and oxygen from the blood are supplied to the cell and waste materials from the cell are exchanged into the blood.
Blood now becomes impure and de-oxygenated
Capillaries join together to form vein-lets and vein-lets combine further into veins
Veins carry de-oxygenated blood or blood that is deprived of oxygen from different parts of the body to the heart for purification
When plaque builds up in the arteries, it interrupts blood flow to organs. This condition is called atherosclerosis. Plaque consists of cholesterol, fats, calcium and other substances found in blood.
