Where the process of diffusion takes place in the human body?

Answer 1

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.

Answer 2

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.

Answer 3

Diffusion takes place in cells throughout the human body, enabling molecules like oxygen and nutrients to move across cell membranes. In the respiratory system, diffusion occurs in the alveoli of the lungs where oxygen enters the bloodstream and carbon dioxide is removed. In the digestive system, diffusion helps in absorbing nutrients from the small intestine into the bloodstream.

Answer 4

These activities all take place in the kidneys, and some in other organs as well.

Answer 5

diffusion happens in the heart in is the process in witch blood moves from a concentrated place to a less concentrated place

Answer 6

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.

Answer 7

In every cell of body

Answer 8

within the cells of your body

Answer 9

the stomach
