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 … Question: 5. Complete the labeling of the diagram of the upper respiratory structures (sagittal section). Learn vocabulary, terms, and more with flashcards, games, and other study tools.
