In brief, state what happens when
A red blood cell is kept in concentrated saline solution?

Explanation

### Step-by-Step Solution:

1. **Understanding the Environment**: When a red blood cell is placed in a concentrated saline solution, the concentration of solutes (salt) outside the cell is higher than the concentration of solutes inside the cell.

2. **Osmosis Process**: Due to the difference in solute concentration, water will move out of the red blood cell into the surrounding saline solution. This movement of water is known as exoosmosis.

3. **Water Loss**: As water exits the red blood cell, the volume of the cell decreases. The cell loses water to balance the solute concentrations on both sides of the cell membrane.
