Question
The larynx, nasal cavities, and pharynx are components of the respiratory tract.
Solution
Yes, that's correct. The larynx, nasal cavities, and pharynx are all important components of the respiratory tract. They each play a crucial role in the process of breathing. The nasal cavities filter, warm, and moisten the air we breathe. The pharynx serves as a pathway for the movement of air from the nasal cavity to the larynx and the esophagus. The larynx, also known as the voice box, not only allows us to speak by vibrating the vocal cords, but also plays a key role in preventing food and drink from entering the windpipe.

The bronchial tree, lungs, and trachea are components of the respiratory tract.
The upper airway system comprises the nose and the paranasal cavities (or sinuses), the pharynx (or throat), and partly also the oral cavity, since it may be used for breathing. The lower airway system consists of the larynx, the trachea, the stem bronchi, and all the airways ramifying intensively within the lungs, such as the intrapulmonary bronchi, the bronchioles, and the alveolar ducts. For respiration, the collaboration of other organ systems is clearly essential. The diaphragm, as the main respiratory muscle, and the intercostal muscles of the chest wall play an essential role by generating, under the control of the central nervous system, the pumping action on the lung. The muscles expand and contract the internal space of the thorax, the bony framework of which is formed by the ribs and the thoracic vertebrae. The contribution of the lung and chest wall (ribs and muscles) to respiration is described below in The mechanics of breathing. The blood, as a carrier for the gases, and the circulatory system (i.e., the heart and the blood vessels) are mandatory elements of a working respiratory system (see blood; cardiovascular system).
