Question 4

describe the process of atherosclerosis

Answer 4

-damage to endothelium caused by something such as high BP (damage can also be caused by cholesterol, smoking, diabetes, old age)
-INFLAMMATORY RESPONSE occurs, WBCs accumulate in area of damage
-cholesterol and lipids accumulate with macrophages UNDER ENDOTHELIUM & form fatty streaks
-fatty streak=under endothelium
-platelets add to the fatty deposit
-combo of all these substances under endothelium forms a plaque called an atheroma
-atheroma narrows lumen of artery, bp higher increasing liklihood of further damage
-over time plaque can calcify and harden reducing elasticity of artery wall, further increasing BP
