Diffusion in liquids. Diffusion can also happen in liquids. This is because the particles in liquids can move around each other, which means that eventually they are evenly mixed. For example if you drop a little bit of paint into a jar of water the colour will spread slowly through the water.This is by diffusion.Diffusion in liquids is slower than diffusion in gases because the particles in a liquid move more slowly.ou don't have to mix the gases by waving your arms around-it mixes on its own. Diffusion in gases is quick because the particles in a gas move quickly. It happens even faster in hot gases. Diffusion happens quickly in gases.
Passive diffusion across tight junctions is the primary mechanism of potassium transport in the colon. The passive uptake of water (which largely follows sodium absorption) serves to convert the liquid ileal contents to semisolid feces. Most water and sodium are absorbed in the ascending and transverse colon.ite: Calcium is absorbed from the duodenum and upper jejunum primarily by an active vitamin D-dependent transcellular process; in the ileum, the predominant process is passive vitamin D-independent, paracellular diffusion. Absorption of Ca ++ in the ileum is about one-third as rapid in the upper small intestine.
