Concept explainers
To label: The structures of the respiratory system in the given figure.
Introduction: The respiratory system is responsible for providing an airway for the movement of air (oxygen) in and out (carbon dioxide) of the body. There are three crucial parts of the respiratory system, namely the muscles of respiration, the lungs, and the airways. The nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles are known as airways.

Answer to Problem 1.1BGL
Pictorial representation:
Fig.1: Structures of the respiratory system.
Explanation of Solution
Pharynx: It is a cone-shaped passageway behind the oral as well as the nasal cavities and above the larynx and the esophagus. It connects the oral and nasal cavities. It acts as a passageway for the movement of food.
Right primary or main bronchus: It is shorter, wider, and more vertical when compared to the left main bronchus.
Lungs: A pair of spongy, air-filled organ that is involved in processing the gas exchange is known as lungs.
Nose and the nasal cavity: The main external opening and the first part of the body’s airway is nose and the nasal cavity. The only visible part of the respiratory system is the nose. The nose includes external nares through which air enters the nasal cavity. The main function of the nasal cavity is to moisten, warm, and filter the air before it reaches the lungs.
Larynx: It is also known as the voice box and it is present at the top of the neck. It is involved in producing sound, breathing, and also protects the trachea from aspiration of food.
Trachea: It is a tube-like system that carries air.
