Question 1

0 out of 10 points

When transitioning from a state of rest to moderate intensity exercise a number of changes occur except:

Selected Answer:

An increase in heart rate and stroke volume

Answers:

An increase in heart rate and stroke volume

An increase in the extraction of O2 from the blood by the muscle

An increase in the sympathetic nervous activity that vasoconstricts vascular beds in non-active tissues

A decrease in mean arterial pressure

An increase in active muscle vascular conductance (flow/MAP)

There are no exception

Response Feedback:

Increases in HR, SV, active tissue vascular conductance, and vasoconstriction in the non-active tissues occurs during the transition from rest to moderate intensity exercise. Because HR and SV increase, so does cardiac output to a great extent and when combined with a small decrease in resistance to flow in some area of the body (gut, inactive tissue etc) the over result is that arterial blood pressure (MAP) will increase from rest.

Question 2

10 out of 10 points

Increased stroke volume occurs during exercise through________________________________________________________

Selected Answer:

an increased left ventricular contractility, increase venous return

Answers:

an increased left ventricular contractility, increase venous return

an decreased left ventricular contractility, increase venous return

an increased left ventricular contractility, decreased venous return

none of these are correct

Response Feedback:

Well done

Question 3
