d. When the foam cells rupture and die, they spill their cholesterol debris within the plaque. Over time, the plaque begins to harden, and at this point it is prone to cracks or ulcerations, which leads to the formation of blood clots. It is these clots that can eventually become thromboses or emboli, leading to heart attacks or…

Plaque (fatty) deposits are cholesterol and other kinds of waste products. Throughout time, these fatty deposits harden while the arteries shrink and stiffen. Due to this, the blood and oxygen supply becomes reduced because it doesn’t flow freely thru the artery. The fatty deposits also enter the bloodstream, causing blood clots which can accelerate to heart myocardial infarction. The main cause would be having damaged inner layers of the arteries. The damage results from hypertension and high cholesterol. There are many contributing factors that cause this such as family history, hereditary and age. These factors can cause the arteries to become less elastic and stiffer, obesity, stress, and lack of…
