The red blood cells would look just fine or normal in the person who has drowned. Water wouldn't be lost because it wouldn't be attracted to the concentration of the salt water and the salt water would be too large to break the barriers.
I would expect to see a withered cell because of the extreme lack of water.
Explanation:
Osmosis is the passage of solvent from a less concentrated solution to a more concentrated solution through a semipermeable membrane until the pressure exerted by the solution on the membrane prevents the passage of solvent. This process aims to balance the concentration of the solution.
Based on this, we can imagine what happens to the cells of a person who drowned in salt water.
Salt water has a higher salt (solute) concentration than human cells, so through osmosis the human cell provided a water outlet (solvent) to dilute the salt of the salt water and establish a balance between the medium. cell phone and salty water. With this extreme loss of water, human cells become wilted and collapse.
