Explain some physiological applications of osmosis and diffusion. Include specific tissue types involved in each.
Osmosis-in the large intestine, water diffuses through the intestinal wall to be received by the cells and blood. Some water does diffuse back in to the intestine due to the difference in water potential. Diffusion-in the respiratory system, as blood travels around the body, oxygenated blood diffuses into the cells and tissues while c 02 is released into the blood to be carried back up to the lungs to be released
