The function of surfactant is/are

A

Facilitating lung expansion

B

Maintaining the stable size of the alveoli

C

To reduce the surface tension on the alveoli

D

All the above

Text Solution

Verified by Experts

The correct Answer is:
d
surfactant is a lipopratein secreted by surfactant seceting cells , which form part of alveolar epithelium. The tends to reduce the surface tension of fluid lining the albeoli and thus faciliates lung expanison and also mantains the stable size of the albeoli.
