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.

Detailed explanation-3: -The respiratory system starts at the nose and mouth and continues through the airways and the lungs. Air enters the respiratory system through the nose and mouth and passes down the throat (pharynx) and through the voice box, or larynx.

Detailed explanation-4: -Lungs. Bronchi and bronchioles. Air sacs (alveoli)
