help!!!! please?

Question

why is diffusion(osmosis) important to humans body? what would happen to the humans bodyif there was no diffusion?
please help

thsnx very much everyone.
reccakun can i know if this is ur answer or u got it from a site, because i really like it and i want to use it, so i dont want to get in trouble.

Answer 1

Diffusion and osmosis move materials into and out of cells -- especially smaller molecules like oxygen, carbon dioxide, and water. Without diffusion, cells could not survive, so the body could not survive. The molecules mentioned above, oxygen, carbon dioxide, and water, must be transported through the plasma membrane by diffusion for cellular respiration and other processes.

Answer 2

Hi Anna,

This is my own answer, and you may use it as you would like. I'm glad I could help!


Hi there,
Diffusion is the passive process of molecules moving from one area to another due to a concentration gradient. A concentration gradient is the concentration difference between two places. For example, the oxygen in the air is a lot more than the oxygen in my lungs. When I inhale, oxygen is actually passively moving into my lungs. It is only really important in terms of atoms and molecules since the process is usually slow. Osmosis is diffusion... but of only water. Diffusion allows the body to obtain nutrients, expel waste, secrete hormones and do many other things. If diffusion of molecules was not possible, then oxygen could not go from your lungs to your blood vessels and from your blood vessels to your cells. Vice-versa, carbon dioxide waste produced by your cells could not enter the blood vessel, and travel to your lungs to be expelled. Most of our bodily functions depend on diffusion, such as the filtration and reabsorption of solutes and water in our kidneys.

I hope this helps!

Answer 3

osmosis is involved in most processes in the body. nutrients are absorbed through the digestive membranes, oxygen is absorbed in the lungs. the endocrine system diffuses hormones and other substances through tissues. the brain uses osmosis to utalize the chemicals that make it work. without osmosis-the movement of liquid through a semi-permiable membrane, there would be no you.

Answer 4

Well Osmosis is the ability for a substance (most commonly water) to break through a semi-permeable membrane. So if water couldnt get through whatever it needs to get through, or other substances that are dangerous could there are plenty of things that could go wrong. A biology expert could give a better explanation then this.

Answer 5

If there was no diffusion, the body's cells would not be able to absorb nutrients or excrete toxins.
