Study Notes

Osmosis

Water moves through semi-permeable membranes in the body by a process called osmosis.
Osmosis is the diffusion of water from areas of high concentration to areas of low concentration.
This movement occurs along an osmotic gradient, across a semi-permeable membrane.
Water moves into and out of cells and tissues depending on the concentration of water and solutes.
Maintaining a balance of solutes inside and outside cells is crucial for normal cellular function.
