  D)
  Loss of plasma proteins causes an increase in interstitial osmotic pressure.

Question 2

Answer to Question 1

Ans:
D

Feedback:

Swelling is the result of plasma proteins leaving the interstitial space, resulting in increased osmotic pressure of interstitial fluid and movement of fluid into tissues. Blood components, vasodilation, nor increased intravascular volume accounts for swelling.

Answer to Question 2

Ans:
D

Feedback:

CSFs participate in hematopoiesis by stimulating bone marrow pluripotent stem and progenitor or precursor cells to produce large numbers of mature platelets, erythrocytes, lymphocytes, neutrophils, and monocytes.
