一.呼吸系统的组成? 答:呼吸系统由鼻、咽、喉、气管、支气管和肺组成。按功能意义,可将呼吸系统划分为两大部分:鼻、咽、喉、气管和支气管,是传送气体的通道,称呼吸道;肺则是容纳气体和进行气体交换的器官。临床上通常又把呼吸道分为上、下两部分:鼻、咽、喉为上呼吸道;气管、支气管为下呼吸道。 A composition of the respiratory system? A: The respiratory system consists of the nose, pharynx, larynx, trachea, bronchus and lungs. In a functional sense, the respiratory system can be divided into two parts: the nose, the throat, the larynx, the trachea and the bronchi, which are the channels that carry the gas and call the airways; the lungs are organs that contain and exchange gas. Clinically, the respiratory tract is usually divided into upper and lower two parts: the nose, pharynx, laryngeal upper respiratory tract; trachea, bronchial lower respiratory tract.
