Answer:

Alveoli

Explanation:

  • Alveoli is the part of the respiratory system which forms the site for an exchange of gases.
  • The exchange is essential to release out carbon dioxide and take in oxygen.
  • Alveoli being the site of gaseous exchange should have the essential features of a good respiratory surface which are -<em> thin, moist and enriched with blood vessels.</em>
  • Due to this, the alveoli are made up of a single layer of epithelial cell and has a network of capillaries surrounding it that carry blood to facilitate the exchange the gases.
