Atherosclerosis pathophysiology correct answers Oxidative damage of vascular endothelium creating inflammation LDLs deposited - damage tunica intima & attract phagocytes Macrophages surround fatty material and create foam cells resulting in a proliferation of smooth muscle cells and a cap over the plaque
Define Ischaemia correct answers a restriction/inadequate blood supply to tissues, causing a shortage of oxygen that is needed for cellular metabolism (to keep tissue alive). generally caused by blockages in blood vessels, with resultant damage / dysfunction of tissue
Atherosclerosis Cause & Risk correct answers Hereditary - male 45+

Two common Aneurysms correct answers AAA - Abdominal Aortic Aneurysm - asym - burst . . =fatal
Berry Aneurysm - cerebrum = haemorrhage
name 3 types of aneurysm correct answers 1. Saccular - single side bulge/ sack like - unilateral 2. Fusiform - balloons bulges all around 3.Dissecting-artery wall rips dissects longitudinally. . This occurs because bleeding into the . weakened wall splits the wall. Dissecting aneurysms tend to affect the thoracic aorta
