where does diffusion occur
Diffusion occurs in the lungs of the body in the alveoli. Oxygen diffuses from the alveoli of the lungs into the small capillaries that surround them and carbon dioxide diffus â¦ es in the opposite direction; this is called gaseous exchange and it happens to oxygenate and get rid of the waste carbon dioide.smosis is the diffusion of water across a semi-permeable (or differentially permeable or selectively permeable) membrane. The cell membrane, along with such things as dialysis tubing and cellulose acetate sausage casing, is such a membrane. The presence of a solute decreases the water potential of a substance.
Report Abuse. well i know for a fact that osmosis(the diffusion of water) occurs in the body cell, but my biology class defines diffusion as the movement of particles from an area of low concentration to an area of high concentration.Hello Â· 8 years ago.est Answer: Lots of places. It occurs with (some) nutrients through the intestinal wall, with oxygen and nutrients from capillaries to cells, with neurotransmitters across synapses, with waste in the kidneys, and with oxygen through the lungs and into the blood stream, just to name a few.
