What is the percentage of salt in the cells?

Each cell can contain a certain amount of salt. It all depends on the type and function of the cell. There are norms for each type of cell. Let’s consider everything using the example of erythrocytes. In human erythrocytes, 0.9% salt is in the cell and in the liquid outside. When the percentage of salt in the blood changes, the red blood cell can be destroyed. If the salt level rises, the red blood cells shrink. With a decrease in the level of salt in the blood plasma, erythrocytes swell. All due to diffusion and an attempt to equalize the amount of salt in the cell and plasma. Therefore, the amount of salt depends on the environment of the cell.
