What Is The Importance Of Diffusion In The Human Body?

Diffusion is important in the body as it the way oxygen travels from sir in our lungs to red blood cells in our blood.
It is also the process by which carbon dioxide travels from our blood to our lungs from where it can then be exhaled.
The cells also take up some of their nutrients from the blood by diffusion and diffusion is also responsible for our nerves to function as the neurotransmitter diffuses across the synaptic cleft so that the next nerve cell can pick up the signal and pass it along.
It is the basic way in which all nutrients, gases and wastes move in the body unless active transport is required which uses protein carriers instead in place where either diffusion is not possible because of the nature of substance or because it has to be transported to an area with an already high concentration of it.

I know that diffusion occurs in the lungs, it is the passive movement of molecules or particles along a concentration gradient, across the cell membrane. The alveoli in the lungs are the tiny air sacs where the diffusion of the gases oxygen and carbon dioxide occurs.

Diffusion is the process during which molecules move from the higher concentration gradient to the lower concentration gradient by random molecular motion. Human body shows diffusion process in various parts of the body. For example, inhaled oxygen enters from lungs to blood through diffusion. Filtration of urine takes place in kidney(bowman's capsule) and you-shaped tube through diffusion. Water is absorbed into the skin because of the process of diffusion. Filtration of important nutrients from large and small intestine also results because of diffusion.

One place in the diffusion takes place in the body is in the lungs, where the carbon dioxide is exchanged for oxygen.

Diffusion is really important in out body , because without diffusion , we all dead
