Question

Difference between child and adults respiratory system

Answer 1

lungs of kids are comparatively smaller than that of adults

Answer 2

When your child breathes out, carbon dioxide leaves the body through the airways, windpipe, and mouth or nose. Breathing out is called expiration. Achild's respiratory system is similar to an adult's. ... The windpipe (trachea) provides a pathway for air to enter and exit the lungs.
But the main difference is, the respiratory rate of a child approx 15-25 in a minute and the respiratory rate of a adult is 10- 20(approx) in a minute.
