How is the sympathetic nerve influence different between the heart and the arterioles, and why is this important?
a) Sympathetic stimulation increases heart rate and arteriolar constriction, promoting increased blood flow to tissues.
b) Sympathetic stimulation decreases heart rate but increases arteriolar dilation, ensuring efficient blood supply to tissues.
c) Sympathetic stimulation increases both heart rate and arteriolar dilation, maximizing blood flow during periods of increased demand.
d) Sympathetic stimulation decreases both heart rate and arteriolar constriction, conserving energy during rest.
