Question

Click and drag each label into the correct category to indicate whether the scenario would cause crenation (shrinking), hemolysis (swelling), or no change in a red blood cell.

Answer 1

Question options:

1. Placing a red blood cell in distilled water

2. Placing a red blood cell into an isotonic solution

3. Placing a red blood cell into a hypotonic solution

4. Placing a red blood cell into a hypertonic solution.

5. Placing a red blood cell with a concentration of 0.9% NaCl into a solution of 1.5% NaCl

6. Placing a red blood cell with an ICF concentration of 0.9% NaCl into a solution with 0.1% NaCl.

Answer:

Crenation (shrinking):

-Placing a red blood cell into a hypertonic solution.

-Placing a red blood cell with a concentration of 0.9% NaCl into a solution. of 1.5% NaCl

Hemolysis (swelling):

-Placing a red blood cell in distilled water.

-Placing a red blood cell into a hypotonic solution.

-Placing a red blood cell with an ICF concentration of 0.9% NaCl into a solution with 0.1% NaCl.

No change:

-Placing a red blood cell into an isotonic solution.

Step-by-step explanation:

Crenation is an osmotic process in which blood cells shrink while placing hypertonic or alkaline solutions. Hemolysis is the destruction of red blood cells in which cells bloat up and may explode while placing in a hypotonic or acidic solution. The blood cells have no change In an isotonic environment because the relative concentrations of solute and water are equal on both sides of the membrane.
