Detailed explanation-1: -Pharynx (throat): Tube that delivers air from your mouth and nose to the trachea (windpipe). Trachea: Passage connecting your throat and lungs. Bronchial tubes: Tubes at the bottom of your windpipe that connect into each lung. Lungs: Two organs that remove oxygen from the air and pass it into your blood.
Detailed explanation-2: -The nasal cavity is the most cephalic part of the respiratory tract. It communicates with the external environment via the anterior apertures, nares, and the nasopharynx via the posterior apertures, choanae.
Detailed explanation-3: -The respiratory system includes the nose, mouth, throat, voice box, windpipe, and lungs. Air enters the respiratory system through the nose or the mouth. If it goes in the nostrils (also called nares), the air is warmed and humidified.
