Document Summary
The exchange of a gas between the respiratory medium (air) and the capillary of the gas exchanger (lungs: gas transport. Where the gases are transported from the gas exchanger (lungs) to the tissues (via the circulatory system: internal respiration the gases are exchanged between the tissue capillaries and the cells, cellular respiration. Involves the actual utilization of o2 by the metabolic processes (within the cells) of the tissues with the result and production of atp, co2, h2o, heat. Involves the mechanism whereby the respiratory medium (air) periodically is replenished/replaced at the gas exchanger (lungs) to allow for continued er (external respiration) Respiratory tree: conducting zone (dead air space) (zone #1) Includes all the passageways no gas exchange occurs. Purify, humidify, and warm incoming air on its way to the rz: respiratory zone (zone #2) Respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli: all contain some alveoli, all involved w/gas exchange. Posterior nasal aperture: nares are the anterior openings.
