The graph below can be used to understand the forces underlying the movement of fluid between the blood and the interstitial fluid.What is a true statement concerning these processes?
A)Sodium ions contribute significantly to the movement of fluid in region B.
B)In people suffering from severe liver disease or protein starvation,the fluid flow in region B is increased.
C)Edema results from reduction of fluid flow in region A.
D)Fluid leaves the blood in region A and returns to the blood in region B.
E)Normally,the net amount of fluid flow in region A is less than the net amount of fluid flow in region B.

Quizplus · Accepted Answer

The graph shows that fluid leaves the blood in region A and returns to the blood in region B, indicating that D is the correct statement. A implies that sodium ions are the main contributor to fluid movement in region B, which is not supported by the graph. B is not supported by the graph and is misleading. C is not supported by the graph, as the reduction of fluid flow in region A does not necessarily lead to edema. E is incorrect, as the net amount of fluid flow in region A is greater than the net amount of fluid flow in region B.
