ANATOMY

Detailed explanation-1: -When you inhale through your nose or mouth, air travels down your pharynx (back of your throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into two air passages called bronchial tubes. One bronchial tube leads to your left lung, the other to your right lung.

Detailed explanation-2: -The PHARYNX (throat) collects incoming air from your nose and passes it downward to your trachea (windpipe). The EPIGLOTTIS is a flap of tissue that guards the entrance to your trachea. It closes when anything is swallowed that should go into the esophagus and stomach. The LARYNX (voice box) contains your vocal cords.

Detailed explanation-3: -Air is inhaled through the mouth or the nose. The sequence of air passage during inhalation is as follows: Nostrils→pharynx→larynx→trachea→alveoli.

Detailed explanation-4: -Air enters the respiratory system through the nose or the mouth, then travels down a pathway to the lungs. In the nostrils, air gets warmed and moistened. Tiny hairs in the nose called cilia (SIL-ee-uh) filter out dust and other particles.

Detailed explanation-5: -As the air passes through the nasal cav ity, mucus and hairs trap any particles in the air. The air is also warmed and moistened so it won’t harm delicate tissues of the lungs.
