Question

Which of the following statements is accurate?

Select one:

a. breathing outward increases the stroke volume of the heart

b. vasoconstriction of digestive organ arterioles is expected upon norepinephrine release from SNS neurons

c. vasoconstriction of the femoral vein is expected upon epinephrine release from the adrenal medulla

d. lymph nodes are primarily charged with selecting which types of immune cells we will sustain with mitosis

e. reentry of fluid from the interstitial space is expected on the arterial end of a capillary

Answer 1

Option B

Upon the release of norepinephrine, the arterioles in the gastrointestinal tract will constrict due to the effects if norepinephrine (alpha receptors action)

Actually inspiration will cause increase in the stroke volume due to increase in the venous return

Veins have less muscle tissue and thus are least affected by vasoconstriction or vasodilation

Thymus is involved in selection of the immune cells

Reentry of interstitial fluid occurs at the venous end

Hope this helps... Thank you!!!
