If the following events in the aetiology and pathogenesis of atherosclerosis were placed in order, which would be 4th?Question 29Select one:a.Damage to the endothelium of medium-large arteries.b.Formation of a fatty streak.c.Formation of foam cells.d.Initial deposition of LDLs and infiltration of macrophages.e.Calcification (particularly of stable atheromas) in arteries.

A thrombus may form on top of a healed myocardial infarct (i.e. scar tissue) because:?Question 14Select one:a.The healed infarct would lead to laminar blood flow.b.Exposing collagen (in the scar) to the blood (in the heart) can initiate platelet aggregation.c.The healed infarct would lead to blood hypocoagulability.d.Scar tissue would increase prostacyclin release from endothelial cells.e.The scar is likely to rupture, leading to release of lipid into the bloodstream.
