BIOS 255 EDAPT week 3select all that are true of capillaries - ANS - fenestrated capillaries allow for fast filtration and
absorption
- sinusoidal capillaries are found in bone marrow
- continuous capillaries are the most common type
which of the following is true of vasoconstriction - ANS - decrease in blood flow and an increase
in blood pressure
under the microscope, a blood vessel is observed to have a relatively thin wall, a large lumen, is
collapsed, and contains a thick tunica externa. this is probably a(n): - ANS - vein
which of the following is not a mechanism that assists venous return - ANS - an increase in
peripheral resistance
select all that occur during bulk flow across a typical capillary - ANS - reabsorption
- movement of fluids and solutes into the capillary
- filtration
- movement of fluids and solutes out of the capillary
the blood flow to the body organs ____ - ANS - is inversely proportional to the resistance of the
arterioles leading to them
the ____ the radius of a vessel , the greater the resistance - ANS - smaller
as the radius of a vessel increases, the resistance ___ - ANS - decreases
as the resistance decreases, the blood flow _____ - ANS - increases
the _____ the radius of a vessel, the less the resistance - ANS - larger
blood flow to an organ will decrease with ______ - ANS - vasoconstriction
blood flow to an organ will increase with _______ - ANS - vasodilation
a patient's systolic pressure is 130 and diastolic pressure is 90. what is the pulse pressure -
ANS - 40 mmHg
capillaries have only a _____ - ANS - tunica intima
, continuous capillaries - ANS - vessels that allow only small nutrients through via simple
diffusion
sinusoidal capillaries - ANS - vessels that lack a basement membrane and are typically found in
red bone marrow and liver
fenestrated capillaries - ANS - vessels that are ideal for moving large nutrients to be absorbed
and wastes to be filtered
elastic arteries - ANS - found close to the heart
- largest of the arteries
- tunica media composed of smooth muscle and elastic connective tissue
muscular arteries - ANS - second largest of the arteries
- found far from the heart
- tunica media composed of smooth muscle
which form of membrane movement is ideal for the diffusion of gases - ANS - simple diffusion
which major category of tissues is ideal for lining and covering endothelial - ANS - epithelial
tissue
Place the events of the autonomic blood pressure regulation in the correct sequence. - ANS -
blood pressure increase
- blood pressure wall stretches
- baroreceptors in vessels increase firing rates
- sensory input sent to cardiovascular center
- cardioacceleratory center decreases nerve signals along sympathetic pathways
- heart rate and stroke volume decrease
- blood pressure returns to resting levels
select all of the following that could potentially result in an increase in arterial pressure - ANS -
vasoconstriction of arterioles
- increase cardiac rate
- increase in stroke volume
the best estimate of MAP is ____ - ANS - the diastolic pressure plus one-third of the pulse
pressure
Whenever blood pressure ______ , the cardiovascular center of the brain stem increases
______, nerve innervation towards the SA node increases heart rate leading to a return in
homeostasis. - ANS - decreases
- sympathetic
