as food particles go from the small intestine through the villi and into the capillaries. When nutrients and oxygen goes from the capillaries into other body cells.
Gas exchange in the lungs as oxygen and CO2 are exchanged. but mainly the first two.
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. Gas exchange in gills and lungs operates by this process. Carbon dioxide is produced by all cells as a result of cellular metabolic processes. Since the source is inside the cell, the concentration gradient is constantly being replenished/re-elevated, thus the net flow of CO2 is out of the cell. Metabolic processes in animals and plants usually require oxygen, which is in lower concentration inside the cell, thus the net flow of oxygen is into the cell. Osmosis 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. Thus there is more water per unit of volume in a glass of fresh-water than there is in an equivalent volume of sea-water. In a cell, which has so many organelles and other large molecules, the water flow is generally into the cell.
These activities all take place in the kidneys, and some in other organs as well.
diffusion happens in the heart in is the process in witch blood moves from a concentrated place to a less concentrated place
The most often occurring area of diffusion is your blood stream. Blood is diffused through capillaries, which are thin walls of the blood vessel allowing the blood to pass through it.

Diffusion can take place in any substance, cause diffusion means the mixture of gases . In a perfume shop diffusion takes place
Blastocyst formation
The important process that takes place in a cell is respiration and this occurs in the mitochondria.
Diffusion is the spreading out of a substance from a region where it is in higher concentration to one where it is in lower concentration. Osmosis is the special case of diffusion where the process takes place through a semi-permeable membrane, i.e. one which allows only some substances through it.
Gaseous excange takes place in the alveoli of the Lungs during respiration
Diffusion.
In a cell in the human body diffusion takes place in the cell membrane. The cell membrane allows smaller sized molecules to pass through.
Blood cells
diffusion takes place in the alveoli
Facilitated diffusion
in liqiuds and gases whrer diffusion is taking place we are dealing with a process called intimate mixing
Diffusion is the process in which particles seek equilibrium. They do so by moving to low concentration from high concentration.
Respiration takes place in body tissues and the lungs be the process of diffusion where CO2 and oxygen are exchanged.Read more: What_is_an_example_of_diffusion_in_living_organisms
