Learn vocabulary, terms, and more with flashcards, games, and other study tools. These structures pull in air from the upper respiratory system, absorb the oxygen, and release carbon dioxide in exchange. The upper respiratory tract is composed of the structures that are located outside the chest cavity or thorax, including the nose, nasopharynx, oropharynx, laryngopharynx, and larynx. The lower respiratory tract is located almost entirely within the thorax and is composed of the trachea, all segments of the bronchial tree, and the lungs.

The conducting tract consists of airways that transport gases into and out of the … The respiratory tract has two major divisions: the upper respiratory tract and the lower respiratory tract. Respiratory system (Systema respiratorum) The respiratory system, also called the pulmonary system, consists of several organs that function as a whole to oxygenate the body through the process of respiration (breathing).This process involves inhaling air and conducting it to the lungs where gas exchange occurs, in which oxygen is extracted from the air, and carbon dioxide expelled from the … In addition to these organs, certain muscles of the thorax (the body cavity that fills the chest) are also involved in respiration by enabling breathing. The lower airways or lower respiratory tract includes the portion of the larynx below the vocal folds, trachea, bronchi and bronchioles.
