Foam cells in a fatty streak are quizlet
WebIt consists of aggregates of foam cells, which are lipoprotein-loaded macrophages, located in the intima, the innermost layer of the artery, beneath the endothelial cells that layer the lumina through which blood flows. Fatty streaks may also include T cells, aggregated platelets, and smooth muscle cells. WebThe fatty streak is the earliest visible lesion of atherosclerosis; it is an accumulation of lipid-laden foam cells in the intimal layer of the artery. The atherosclerotic plaque is the hallmark of atherosclerosis; it is an evolution of the fatty streak and has 3 major components: Lipids Inflammatory and smooth muscle cells
