What is the function of the type ii alveolar cell?

The function of the Alveolar type II cells is that they secrete a lipoprotein material that is known as surfactant.  The  primary function of the surfactant is to reduce the surface tension in the alveoli.

Explanation:

Type II have an important function Type II as they secrete pulmonary surfactant in order to lessen the surface tension of water and allows the membrane to separate, therefore increasing its capability to exchange gases.

b. lithosphere, asthenosphere, mesosphere   is the answer most likely
