Question Answer
the layer in the wall of an artery that is smooth to prevent abnormal clotting issimple squamous
the layer in the wall of the artery that prevents rupture of the artery is the outer layer of fibrous connective tissue
the layer in the wall of an artery that helps maintain blood pressure ismiddle layer of smooth muscle and elastic connective tissue
in veins the outer layer is thinner than in arteries becauseblood pressure in veins is so low that rupture is unlikely
the function valves in veins is to prevent backflow of blood
the function of the lining in booth veins and arteries is to preventabnormal clotting
capillaries are made of simple squamous epithiliium becausethis tissue is thing to permit exchange of materials
in capillaries oxygen and carbon dioxide are exchanged by diffusion
capillaries carry blood from arterioles to venules
artieries carry blood from the heart to capillaries
veins carry blood fromcapillaries to the heart
in pulmonary circulation blood is pumped to the lungs bythe right ventricle
pulmonary circulationright ventricle to lungs to left atrium
the fetal structure that permits blood flow from the right atrium to the left atrium is the foramen ovale
the hormoe that raises blood pressure by increasing heart rate isepinephrine
a bp reading hassystolic reading first
systolic equalsleft ventricle contracting
diastolic equalsleft ventricle relaxing
term for high blood pressure ishypertension
diameter of arteries and veins is regulated by a center in the medulla
