At Which Developmental Stage Do the Type II Alveolar Cells

Question

A) the eighth fetal month
B) the end of the fourth fetal month
C) the end of the sixth fetal month
D) early fifth fetal month
E) early third fetal month

Accepted Answer

At the end of the sixth fetal month, the type II alveolar cells begin producing surfactant. Surfactant helps to decrease surface tension within the alveoli and prevent their collapse during expiration, and it is essential for proper lung function after birth.
