Breathing 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?
During inhalation, the air for the respiration is drawn into our body through the nostrils, then it goes into nasal passage. From there, oxygen enters into pharynx, larynx then into the windpipe, bronchi, lungs and finally to the alveoli where gaseous exchange take place.
