Pick the correct answer to the following question. Write a brief statement explaining why each choice of answers is correct or incorrect.

In diabetes mellitus, because of insufficient insulin production, glucose cannot enter cells. instead it accumulates in the blood plasma. which of the following statements would be true under these conditions?
A. The concentration of the plasma would decrease.
B. the osmotic pressure of the plasma would remain the same.
C. Water would move out of the tissues into the plasma.
D. Tissue cells would swell.

The correct answer to the given question is C. Water would move out of the tissues into the plasma.

Explanation for each choice of answers:

A. The concentration of the plasma would decrease.
This statement is incorrect. In diabetes mellitus, because glucose cannot enter cells and accumulates in the blood plasma, the concentration of glucose in the plasma would increase, not decrease.

B. The osmotic pressure of the plasma would remain the same.
This statement is incorrect. In diabetes mellitus, the accumulation of glucose in the blood plasma would increase the osmotic pressure of the plasma. This is because glucose is an osmotically active substance, meaning it contributes to the osmotic pressure of the plasma.

C. Water would move out of the tissues into the plasma.
This statement is correct. Due to the accumulation of glucose in the blood plasma, the osmotic pressure in the plasma increases. This higher osmotic pressure causes water to move from the tissues into the plasma by osmosis, in an attempt to balance the concentration of solutes.

D. Tissue cells would swell.
This statement is incorrect. In diabetes mellitus, tissue cells would actually shrink or become dehydrated. This is because water moves out of the tissues into the plasma, resulting in a reduced water content in the cells. Therefore, the tissue cells would not swell.
