Question

heart rate and stroke volume decrease with a decrease in parasympathetic stimulation. true or false true false

Explanation:

Parasympathetic stimulation generally slows the heart rate (bradycardia) and has a minor effect on stroke volume. A decrease in parasympathetic stimulation would lead to an increase in heart rate (as the opposing sympathetic influence may become more dominant in the absence of strong parasympathetic brake) and may have some impact on stroke volume regulation. So the statement that heart rate and stroke volume decrease with a decrease in parasympathetic stimulation is incorrect.

Answer:

False
