Answer:
It is currently believed that the process begins as a result of damage to the endothelium. The first recognizable change is the appearance of fatty streaks, gray-white areas that protrude into the lumen of the artery. More advanced lesions are called fibroatheroma.
Step-by-step explanation:
The process of atherosclerosis is progressive and is responsible for coronary artery disease. Atherosclerosis occurs due to formation of plague in arteries and this plague is composed of cholesterol, fat, calcium, minerals and toxic substances. The atherosclerotic plague deposition starts damaging the inner lining of arteries known as endothelium. the changes that occur with time as a result of plague deposition include fatty streaks appearing in the tunica intima whereby, this grey white fatty matter deposits into the lumen making it worse. Hence, advanced lesions are formed known as fibrous atheroma causing myocardial infarction.
