1.5 - Arthersclerosis

Question 1

What does a healthy blood vessels have?
(endothelium, proteins, muscles, elastic fibres and layers)

Answer 1

smooth endothelium and acts as protective barrier
secretes proteins to prevent blood clots
smooth muscular walls and thick elastic tissue to withstand blood pressure and recoil
layers help blood flow effieciently

Question 2

What is the process of arthersclerosis?

Answer 2

Irritants damge the endothelium
cholesterol sticks to damaged endothelium
triggers an inflammatory respsonse
fatty deposits forms
more WBC and cholesterol builds up = atheroma
partial blocked lumen = positive feedback loop
artery loses flexibility
= Athersclerosis
