Document Summary

Focus is normal respiratory physiology as basis for understanding its pathophysiology. External respiration: exchange of gases between the lungs and outside air. Internal respiration: the exchange of gases between blood and various tissues. Transport of oxygen and carbon dioxide in blood. Regulates the blood"s hydrogen ion concentration (ph) in coordination with the kidneys. Influences arterial concentrations of chemical messengers by removing some from pulmonary capillary blood and producing and adding others to this blood. Traps and dissolves blood clots arising from systemic (usually leg) veins. Functions of the conducting zone of the airways. Provides a low-resistance pathway for air flow; resistance is physiologically regulated by changes in contraction of airway smooth muscle and by physical forces acting upon the airways. Defends against microbes, toxic chemicals, and other foreign matter; cilia, mucus, and macrophages perform this function. The major parts of the airways used in ventilation (breathing). Conducting zone the relaxation/contraction of circular smooth muscle lining these.
