B)increase of heart rate and force
C)dilation of the vessels serving the skeletal muscles
D)constriction of most blood vessels

Question

Quizplus · Accepted Answer

The sympathetic division of the autonomic nervous system typically causes constriction of most blood vessels, including those serving the skin and digestive viscera, and dilation of the vessels serving the skeletal muscles. It also increases heart rate and force, which can lead to an increase in blood pressure. Therefore, the correct answer is A, as dilation of blood vessels serving the skin and digestive viscera is not a cardiovascular effect of the sympathetic division.
