In human beings, gaseous exchange occurs through alveoli – a semipermeable membrane present inside the lungs.
Explanation:
- These structures are present in abundance as clusters inside the lungs, at the end of each bronchus. Alveoli are very thin and delicate structures.
- When there is a large surface area, and the membrane is thin, there is increased rate of diffusion. The alveoli have the thickness of one cell, which allows in the easy exchange of oxygen and carbon dioxide.
