what does it mean to be more viscous
Viscosity The viscosity of a fluid is the measure of its resistance to gradual deformation by shear stress or tensile stress.[1] For liquids, it corresponds to the informal concept of "thickness": for example, honey has a higher viscosity than water.[2]
Atherosclerosis Atherosclerosis (also known as arteriosclerotic vascular disease or ASVD) is a specific form of arteriosclerosis in which an artery wall thickens as a result of invasion and accumulation of white blood cells (macrophages and foam cells) and proliferation of intimal-smooth-muscle cell creating an atheromatous (fibrofatty) plaque.[1][2]
