See lessBreathing is the process that brings oxygen in the air into your lungs and moves oxygen and through your body. It involves two processes- inhalation (breathing in) and exhalation (breathing out). Which is the correct sequence of air passage during inhalation?
[D] Nostrils → pharynx → larynx → trachea → alveoli
