Cardiovascular system: blood vessels and hemodynamics Flashcards
what is the development of blood vessels
angiogenesis
what conducts blood away from the heart
arteries
what is the small vessels that permit gas, nutrient, and waste exchange
capillaries
what conducts toward the heart
veins
what are the three types of arteries
elastic, muscular, and arterioles
what are the largest arteries in the body that are also known as conducting arteries
elastic arteries
what are the distributing arteries that carry blood to specific organs of the body and have a thick layer
muscular arteries
what are the resistance vessels that are the smallest and can contract smooth muscle in their walls
arterioles
what is a short connecting vessel between an arteriole and its branching capillaries
metarterioles
where does transfer of nutrients, gases, and waste occur
capillaries
what are the three types of capillaries
continuous, fenestrated, and sinusoids
what type of capillaries have continuous lining of endothelial cells and only have a small opening in the walls
continuous capillaries
what type of capillaries have intercellular clefts and small holes or fenestrations
fenestrated capillaries
what type of capillaries has a wider lumen, has fenestrations that are larger, and has an incomplete or lacking basement membrane
sinusoid capillaries
what carries blood towards the heart
veins
what receives blood from the met arterioles
venules
what receives blood from venules
veins
what is the venous structures that contain no smooth muscle cells
venous sinus
what kind of tissue is made of simple squamous epithelium and makes the inside layer of the vessels
endothelial tissue
what kind of tissue is made of protein strands woven in the vascular wall and is fairly flexible but still provides a great amount of support
collagen fibers
what kind of tissue is highly stretchable and allows for recoil after distention and maintains passive tension in the vessels
elastic fibers
what kind of tissue is not found in capillaries is involuntary muscle and responsible for dilating/constricting the blood vessels
smooth muscle tissue
what is the outermost layer of blood vessels
tunica externa
what layer of the blood vessels is made of fibrous connective tissue and in veins it is the thickest layer but it is thinner in arteries
tunica externa
what is the middle layer of blood vessel
tunica media
what layer of the blood vessels is made of smooth muscle and elastic fibers and is very thick in arteries and much thinner in veins
tunica media
