Detailed explanation-1: -What is an example of simple diffusion in the human body? An example of simple diffusion in the body occurs in the lungs. Oxygen molecules flow from high concentration in the lungs, across the semipermeable membrane lining the lungs, and enter the oxygen-deficient blood vessels.

Detailed explanation-2: -The correct answer is Diffusion. It is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.

Detailed explanation-3: -Simple diffusion A process in which the substance moves through a semipermeable membrane or in a solution without any help from transport proteins. For example, bacteria deliver small nutrients, water and oxygen into the cytoplasm through simple diffusion.
