3. What would happen if the tubing with the yellow band was placed in a beaker of distilled water? If the tubing with the yellow band was placed in a beaker of distilled water, it would swell in volume. This would occur because the solution inside would be hypotonic compared to the distilled water. The distilled water would move into the bag to the higher concentration. 4. How are excess salts that accumulate in cells transferred to the blood stream so they can be removed from the body? Explain how this process works in terms of tonicity. In terms of tonicity, the body will try to become isotonic and remove the extra salt because the salt water is hypertonic to the cells. It has a higher concentration and lacks water; therefore, the water moves out of the cell and will then shrink. This allows for equilibrium to be reached. In simpler terms, the solution of salts inside the cell is hypertonic in comparison to the blood stream. The salts will move through the semipermeable membrane of the cell to the less concentrated blood stream.
