Question

State an example of a cell and an organ from the gas exchange system. *

Answer 1

Answer:

cells- alveoli cells

organ- lungs

Explanation:

alveoli cells are present at alveolus . alveolus is the smallest unit of lungs. the air taken in by lungs ultimately reaches alveolus.

The thickness of alveolus is only single cell epithelium.

diffusion occurs here and Oxygen is exchanged to carbon dioxide (through alveolus cells).So gas exchange cells are alveolus cells

gas exchange( i.e. oxygen and carbon dioxide diffusion ) occurs at lungs . So gas exchange organ is lungs
