Document Summary
What are the three layers of most blood vessels: tunica inima, tunica media, tunica adveniia (external) Tunica media: smooth muscle and external elasic membrane. Tinuca inima- endothelial cells, subendothelial layer and internal elasic membrane. What are the three types of arterial vessels? (from closest to furthest from heart: elasic arteries (conducing, muscular arteries (distribuing, arterioles. What are the three types of capillaries: coninuous, fenestrated, sinusoid. Microcirculaion is the travel of blood from an arteriole through a capillary bed and to a venule. Quote far away from heart, blood pressure is lower, so there is litle or no elasic issue. Adaptaions that help blood move: valve structures are throughout veins, makes sure that blood doesn"t low backwards, skeletal muscle. When the muscles move and contract, they squeeze against the vein, pushing blood in the right direcion. Blood low: the volume of blood lowing through a issue/organ/body in a given period of ime.
