Unformatted text preview: x most important pressure that aids ﬁltration from the capillary is the:
hydrostatic pressure in the capillary.
t colloid osmotic pressure in the capillary
(7 . colloid osmotic pressure in the interstitial ﬂuid.
D. interstitial oncotic pressure Edema can be caused by:
increased lymphatic drainage
leakage of plasma proteins into the interstitium
arterial obstruction aldosterone
acetyl choline \i @e hormone that promotes elimination of sodium (and consequently water) from the body is:
C ADI-I (anti diuretic hormone) renin
ANP (atrial natriuretic peptide) y "stance to blood ﬂow in a vessel would be increased by:
a decreasing the radius of the vessel. '
. decreasing the length of the vessel
C. decreasing the blood viscosity
D . increased NO release
E. vasodilation ll 35 pathetic nervous system activity would be expected to:
increase the venous return
decrease the heart rate C. decrease the heart contractility
/D.” increase parasympathetic activity as well. E. cause the capillaries to contract
\/ Autoregulation of local blood ﬂow:
depends on the ANS (autonomic nervous system) innervation.
is accomplished through both myogenic and metabolic mechanisms.
makes sure that the capillary pressure never changes. depends on the lymphatic system.
maintains a constant blood ﬂow all the time. D.

decreases in the skeletal muscle circulation and increases in the gut circulation

. increases in both the gut circulation and the skeletal muscle circulation
E. decreases in the cutaneous circulation and increases in the muscle circulation. 3%. If you were to suddenly increase the end-diastolic volume, you Would expect arterial pressure t ly leading to a subsequent in the discharge of the baroreceptors.
