Question

if the heart receives more sympathetic stimulation than parasympathetic stimulation, the heart will
multiple choice
increase its rate and force of contraction
contract with greater force but at a slower rate.
decrease both its rate and force of contraction.
contract with less force but at a faster rate.
decrease rate, but increase force of contraction.

Explanation:

The sympathetic nervous system stimulates the heart to increase its activity. It causes an increase in the heart - rate (chronotropic effect) and an increase in the force of contraction (inotropic effect). This is part of the body's "fight - or - flight" response.

Answer:

increase its rate and force of contraction
