Document Summary

Involved in the uptake portion of vo2 and removal portion of vco2. Important in acid-base status (co2 + h+: co2 - weak acid, h+ ion - very acidic, thermoregulation - we lose body heat through ventilation. Anatomy of the lung: nasal cavity + mouth go to throat, pharynx - space between mouth and larynx, trachea goes to lungs, esophagus has a bifurcation that leads to the stomach. Lungs: primary bronchi, bronchioles, alveoli / capillary system, gas exchange occurs here. Laid out flat - 1/2 size of a tennis court: exchange of gases is called respiration, areas where gas exchange does not occur is called dead space, key function is to increase surface area for gas exchange. Mechanics of ventilation: 2 types of pressure in the lungs: Intrapleural - in the pleural space: action of the diaphragm and costal muscles affects these pressures, causing inspiration and expiration, volume is indirectly proportional to pressure, at rest, diaphragm does the work.
