Question

An acute decrease in mean arterial pressure (by getting up very quickly, for instance) will cause (true or false):

Group of answer choices

a decrease in parasympathetic output*

      [ Choose ]            false            true      

a decrease in sympathetic output

      [ Choose ]            false            true      

a reduction in the heart rate

      [ Choose ]            false            true      

an increase the total peripheral resistance*

      [ Choose ]            false            true      

an increase in action potential frequency from the aorta and carotid sinus

      [ Choose ]            false            true   

Answer 1

Arterial BP is a function of product of Cardiac output & Peripheral resistance, therefore its affected by either or both of these factors.

True/ False statement:

1. A decrease in Parasympathetic output - False

2. A decrease in Sympathetic output- True

3. A reduction in heart rat- True

4. A Increase in Total Peripheral resistance- False

5. A increase in Action Potential from aorta & carotid sinus- False
