b. peripheral svasoconstriction
c. constriction sof sbronchial ssmooth smuscle
d. increased sforce sof smyocardial scontraction
ANSWER: s B
Alpha1 sreceptors sare sfound sin sthe seyes, sblood svessels, sbladder, sand smale sreproductive
sorgans.sStimulation sof salpha1 sreceptor ssites sresults sin sconstriction.
OBJ: s Compare sand scontrast sthe seffects sof ssympathetic sand sparasympathetic sstimulation sof sthe sheart.
8. Which sside sof sthe sheart sis sa slow-pressure ssystem sthat spumps svenous sblood sto sthe slungs?
a. Left
b. Right
ANSWER: s B
The sjob sof sthe sright sside sof sthe sheart sis sto spump sunoxygenated sblood sto sand sthrough sthe
slungs sto sthe sleft sside sof sthe sheart. sThis sis scalled sthe spulmonary scirculation. sThe sright sside sof
sthe sheartsis sa slow-pressure ssystem.
