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 body. Inhalation is an active motion that causes the diaphragm to contract. Chevalier, F., J. Herbinire-Gaboreau, J. Bertaux, M. Raimond, F. Morel, D. Bouchon, P. Grve, C. Braquart-Varnier.

Get the answers you need, now! body system that circulates blood, oxygen, and nutrients to all the cells of the body. Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells. It is unclear whether movement is constant, allowing the individuals to forage while they go, or if periods of movement are interspersed with periods of foraging and rest. The lungs work to pass oxygen into the body, whilst removing carbon dioxide from the body. The human body is made up of many cells, so it is an example of a multicellular organism.
