Questions And Answers | With 100% Correct Answers graded A+
Guaranteed Success!!
Aneurysm - (ANSWER)part of arterial wall thins and balloons out making the wall prone to rupture
Athersclerosis - (ANSWER)"Hardening" of the arteries (elastic and muscular) results from plaques which
thicken the interior walls and narrow the lumen
Myogenic response - (ANSWER)smooth muscle in artery/arteriole wall responds to changes in blood
pressure to keep local flow relatively constant
Vasoconstriction - (ANSWER)Increased MP
Vasodilation - (ANSWER)decreased BP
Vasodilators - (ANSWER)dilate arterioles and relax precapillary sphincters
-increase flow into capillary beds
-increase in carbon dioxide, body temperature, nitric oxide, ADP
Vasoconstrictors - (ANSWER)constrict arterioles and cause contraction of precapillary sphincters
-decrease flow into capillary beds
-increase in oxygen, sympathetic tone, Angiotensin II, ADH
Blood Pressure - (ANSWER)is the force of blood against vessel wall
Mean Arterial Pressure (MAP) - (ANSWER)is the average arterial blood pressure across the entire cardiac
cycle in which the diastole lasts longer
=diastolic pressure +1/3 pulse pressure
