How do substances like CO2 and water move in and out of the cell?

The substances like CO2  and water move in and out of a cell by diffusion

Diffusion is a physical process in which the substance or molecules move from the region of higher concentration to the region of lower concentration. This process occurs in all three states of matter – gases, liquids, or solids and is found fastest in gases when compared to liquids and solids.

Diffusion is one of the important processes and essential activities in human organs. Listed below are a few examples of the diffusion process in the living system.

  • Movement of oxygen and carbon dioxide gas in the lungs.
  • Movement of water, salts, and waste products in the kidneys.
  • The movement of calcium from food into cells occurs in the intestines.
  • Movement of the molecules during various metabolic or cellular processes.
