Indicate whether the statement is true or false

Question 2

The normal osmolarity of blood and body fluids is 300 mOsm/L. A person with severe diabetes and a greatly elevated blood glucose has a blood osmolarity of 370 mOsm/L. Which of the following events will result from the increased osmolarity?

A. Water shifts by osmosis from the cells into the extracellular fluid (ECF).
B. No water shifts will occur between the cells and the extracellular fluids as a result of the higher osmolarity of the subject's blood and body fluids.
C. Water shifts by osmosis from the extracellular fluid into the cells.
D. Equal amounts of water move from the cells into the ECF and from the ECF into the cells, and thus, there is no net change in the water content of either the cells or the ECF.
