Down: 2) Arteries can be classified as :5) is the middle layer. The thickest layer. Is composed of smooth muscle and elastic fibers. Its also involuntary.7) is the inner layer. Is composed of endothelium. This layer is in contact with the blood. Is a continuous layer that lines the inner surface of the entire cardiovascular system.9) Blood vessels that carry blood away from the heart and convey it towards the tissues. It is almost always oxygenated blood.12) Are small veins that collect blood from the capillaries and drain it into the veins.13) Makes the lumen of the artery smaller. Is a decrease in the size of the lumen caused by contractions of the smooth muscle cells in the wall of the blood vessels.14) Very small, minute arteries that deliver blood to the capillaries. Are considered the terminal branches of arteries.16) is the largest artery in the body.19) A blood vessel that splits into 2 branches.21) Microscopic vessels that carry blood from the arterioles to small veins called venules. They are the SMALLEST blood vessels. Their function is to permit the exchange of nutrients (oxygen) and waste (CO2) at the cellular level.23) The hollow core through which blood flows.24) Are blood vessels that carry blood towards the heart, away from the tissues. Carry deoxygenated blood. Across: 1) The exception of oxygenated arteries. These carry deoxygenated blood.3) A vessel that dumps into another vessel:4) Composed of dense connective tissue and some elastic fibers.6) A blood vessel that splits into 3 branches.8) Veins have valves that prevent backward circulation also called:10) Is an alternate route of blood to a body part through an anastomosis. Circulation of blood through a secondary channel so as to bypass an obstruction in the main channel.11) Also known as elastic or conducting arteries. The tunica media contains more elastic fibers than smooth muscle cells. Conduct blood to muscular arteries.15) Composed of smooth muscle and elastic fibers. This layer is less developed than in the arteries because there is less pressure than in the arteries.17) makes the lumen larger. An increase in the size of the lumen caused by dilation or relaxation of smooth muscle in the wall of the blood vessel.18) Composed of endothelium20) The tunica media contains more smooth muscle cells than elastic fibers.22) Veins run parallel to arteries also called:25) Has only a few scattered smooth muscle fibers.26) Is composed mostly of elastic fibers.27) Carry oxygenated blood. The exception to deoxygenated blood veins.28) The study of vessels.29) An end to end union of blood vessels. Is the union of branches of 2 or more arteries supplying blood to the same region. Is the joining together of blood vessels. Is the natural communication of blood vessels. Is an alternative route for blood to reach a tissue or organ.30) is found only in larger venules.31) is a vein that accompanies an artery.32) Blood vessels that supply blood to the walls of blood vessels.33) Is the outer layer. Composed of fibrous connective tissue and some elastic tissue. Is the layer that holds the vessels open and prevents tearing of the vessel wall.34) is composed of endothelium.35) Contains more smooth muscle and less elastic tissue.36) Is composed of endothelium, like arteries
