Medicine in English: Upper Respiratory Tract

Upper Respiratory Tract
1. Nose: The nose is the organ through which we smell and breathe.
2. Nasal Cavity: The nasal cavity is the hollow space inside the nose where air is warmed, moistened, and filtered before entering the lungs.
3. Sinuses: Sinuses are air-filled cavities in the skull that lighten the weight of the head and produce mucus that drains into the nasal cavity.
4. Pharynx: The pharynx, also known as the throat, is the passageway for air from the nasal cavity to the larynx and for food from the mouth to the esophagus.
5. Larynx: The larynx, commonly referred to as the voice box, contains the vocal cords and is responsible for producing sound and protecting the lower respiratory tract.
6. Epiglottis: The epiglottis is a flap of tissue that closes over the larynx during swallowing to prevent food and liquids from entering the airway.
