why do fingers and toes shrivel when water?

Answer 1

It is because of crenation.Crenation is the contraction of cells in a hypertonic solution, due to the loss of water through osmosis.

Crenation occurs because in a hypertonic environment (that is, the cell has a lower concentration of solutes in this case ur fingers and toes, than the surrounding extracellular fluid which is water in ur case) osmosis (the diffusion of water) causes a net movement of water out of the cell, causing the cytoplasm to decrease in volume. As a result, the cell shrinks so do ur fingers and toes.

Answer 2

what your seeing is the end result of osmosis. Your body is mostly water while a tub full of water is 100% water. This means that your body is hypotonic and the water is hypertonic. To equalize this your skin cells are going to absorb as much water as possible. This absorbtion causes the cells to expand and thus cause wrinkles.

Answer 3

A thick layer of pores and skin covers all your physique besides factors such as arms and feet. once you sit down in water for long classes of time, your pores and skin will take in the water and improve. yet by using fact your arms and feet have not got this skinny pores and skin, it does not have room to enhance. It purely wrinkles up, like a prune. sturdy success!
