A Drug That Blocks Vagal Activity

Question

A drug that blocks vagal activity
A) slows GI motility and reduces GI secretions.
B) increases the secretion of bile.
C) speeds up peristalsis.
D) causes diarrhea.

Accepted Answer

Vagal activity plays a major role in stimulating GI motility and secretions. Blocking vagal activity would therefore lead to a slowing down of GI motility and a reduction in GI secretions, which corresponds to option A. The other options are unlikely effects of blocking vagal activity.
