Patient's question:
According to the elders, children need to go through a series of developments after birth before they can gradually reach the maturity of various organs. The eyes are about to mature around the age of 10. How old are girls usually when they develop?Doctor's answer:
If the child is a normal full-term baby without congenital developmental abnormalities, lung development is basically complete at birth, although relatively speaking, the ventilatory function of the lungs is lower than that of adults. We commonly use lung capacity to represent respiratory function. Before the age of 20, lung capacity gradually increases with age, but after 20, the increase becomes less significant. The lung capacity of adult males is approximately 3500 to 4000 milliliters, and that of adult females is about 2500 to 3000 milliliters.
