Document Summary
Chapter 38: oxygenation and perfusion: factors essential to normal functioning of the respiratory system. The wall of each alveolus is made of a single- cell layer of squamous epithelium. Internal respiration between the circulating blood and tissue cells must occur: question, tell whether the following statement is true or false, pulmonary ventilation is the process by which oxygenated capillary blood passes through body tissues, a.

Total lung capacity: c. residual volume, d. peak expiratory flow rate, answer, answer: b. Total lung capacity: rationale: total lung capacity is the amount of air contained within the lungs at maximum inspiration. Vital capacity is the amount of air displaced by maximal exhalation. Residual volume is the amount of air left in the lungs at maximal expiration.
