Question
Tabulate adaptations of terrestrial respiration in human being.
✓

Answer

Different respiratory adaptations of human beings are as follows:
  1. All the respiratory organs have a large surface area to get enough oxygen.
  2. All the respiratory organs have thin walls for easy diffusion and exchange of respiratory gases.
  3. All the respiratory organs like skin gills, and lungs have a rich blood supply for transporting respiratory gases.
The thin and delicate respiratory structures must be well protected under layers of tissues so as to protect them from the external environment.
