Describe the process by which plaque forms within arteries
What will be an ideal response?
LDLs deposited along an injured artery's lining become oxidized; immune cells attracted to the site engulf the oxidized LDLs and transform into foam cells, which stick to the artery wall; foam cells accumulate, and with the arrival of platelets and various other circulating substances, thick deposits of plaque form. As the plaque deposit becomes larger, the artery becomes stiffened and narrowed internally, reducing blood flow through the vessel.
