Question

What is one example of diffusion in the human body?

Answer 1

Diffusion:

1. Diffusion is the process of movement of molecules from a region of higher concentration toward a region of lower concentration.
2. It is the process that helps in gaseous movement.
3. In the human body, diffusion helps in gaseous exchange, water, salt, and waste removal from our kidneys.
4. The major advantage of this process is that it doesn't require energy for regulation, as opposed to a cell having to make proteins that pump molecules across a membrane.

Example of diffusion in the human body:

1. Diffusion of oxygen through alveoli in the lungs.
2. A kidney is used to filter out the salts and waste products from our bloodstream.
3. Diffusion of carbon dioxide through alveoli in the lungs.
