Question
At What Age Do Girls Begin to Develop?
Answer
If a child is born at full term without any congenital developmental abnormalities, their lungs are generally fully matured at birth, although their ventilation function is relatively lower than that of adults. Lung capacity represents respiratory function, and it typically increases with age until around 20 years old, after which the increase is not significant. The lung capacity of adult males is approximately 3500 to 4000 milliliters, while for females, it is about 2500 to 3000 milliliters.
