GENERAL HISTOLOGY

Detailed explanation-1: -The sequence of air passage during inhalation is as follows: Nostrils→pharynx→larynx→trachea→alveoli.

Detailed explanation-2: -Air enters your body through your nose or mouth. Air then travels down the throat through the larynx and trachea. Air goes into the lungs through tubes called main-stem bronchi.

Detailed explanation-3: -The air we inhale enters our body through our nostrils. It then passes through the nasal cavity, the pharynx, the larynx and finally enters the windpipe, also known as the trachea. The trachea branches into bronchi which sends air into both the lungs.

Detailed explanation-4: -The air travels through the bronchi from the trachea, and then to the bronchioles and then eventually reaches the alveoli for exchange of gases with blood. The respiratory route of air in the respiratory tract is: Nostrils → nasal cavity →Pharynx → Larynx →Trachea → Bronchi → Bronchioles → Alveoli or air sacs.

Detailed explanation-5: -From the windpipe, air moves into the lungs through tubes called bronchi. The bronchi lead to smaller tubes called bronchioles, which look like the branches of a tree.
