The upper respiratory tract is composed of nose, pharynx and larynx. The nose can warm, humidify and purify the inhaled gas. The air can be heated to about 37 ℃ and reach 95% relative humidity, so that the gas entering the lungs can meet the physiological needs of the human body. Pharynx is the common pathway of respiratory tract and digestive tract. When swallowing, epiglottic cartilage closes the larynx, which plays an important role in preventing food and oral secretions from entering the respiratory tract. The larynx is composed of thyroid cartilage and cricoid cartilage (inner vocal cord). The cricothyroid membrane connects thyroid cartilage and cricoid cartilage. It is generally the site of cricothyroid membrane puncture in laryngeal obstruction.
