Document Summary
Which factor might increase resistance to the flow of blood through the blood vessels: an increased inner radius of diameter of blood vessels, decreased numbers of capillaries, decreased blood viscosity, decreased number of red blood cells. Why does tunica media have smooth muscle: easier for contraction and relaxation of the muscles, since it doesn"t require gas exchange it"s easier for it to recoil compared to capillaries. What"s the difference between ldl and hdl: ldl is the bad fat it needs to be low, it"s made in the liver and is transported to the peripheral tissues where it floats around in the bloodstream. This causes atherosclerosis: hdl good fat it needs to be high, it"s made from the peripheral tissues and is transported to the liver where it"s removed from the body and bloodstream. What"s left over or remains is some bile acids.
