Answer:

The question lacks options, the options are:

A. Your blood cells would stay the same size but could no longer carry oxygen.

B. Your blood cells would stay the same size but could no longer release the oxygen they carry.

C. Your blood cells would enlarge and may rupture.

D. Your blood cells would shrivel.

The answer is D

Step-by-step explanation:

Water moves in and out of a cell in conformity with the concentration gradient formed between the membrane of the cell and the extracellular solution. The process whereby the water moves from a region of low solute concentration to a high solute concentration via a semi-permeable membrane is called OSMOSIS.

In this case, the solute concentration of the blood cannot be regulated, hence, it rises. This causes the solute concentration of the blood to be high or is said to be hypertonic than the cell's. This creates an osmotic gradient causing water to flow out of the hypotonic (low solute concentration) cell into the hypertonic extracellular environment (blood). Once water flows out of the cell as a result of osmosis, the cell shrinks or shrivels i.e. reduce in size.
