Name and briefly describe the three basic processes of respiration. | Ans:|1. Pulmonary ventilation is the movement of air in and out of the lungs due to contraction and relaxation of muscles that control the size of the thoracic cavity. 2. External respiration is the exchange of gases between the air in the alveoli and the blood in the pulmonary capillaries. 3. Internal respiration is the exchange of gases between the blood in the systemic capillaries and tissues. | |Link to: 22. 3 Inhalation and exhalation| 58. |Describe the inward forces of elastic recoil, and explain why the lungs do not normally collapse during expiration.  Human A&P CH. 22 Respiratory System Essay .Ans:|Elastic recoil is the recoil of elastic fibers stretched during inspiration and the pull of the surface tension of alveolar fluid. Intrapleural pressure is always subatmospheric during normal breathing, which tends to pull lungs outward and to keep alveolar pressure from equalizing with atmospheric pressure. Surfactant in alveolar fluid decreases surface tension to help prevent collapse. | |Link to: 22. 3 Inhalation and exhalation Inhalation and exhalation, 22. 5: Oxygen and carbon and 22. 6: Respiration| 59. |In chronic emphysema, some alveoli merge together and some are replaced with fibrous connective tissue.

In addition, the bronchioles are often inflamed, and expiratory volume is reduced. Using proper respiratory system terminology, explain at least four reasons why affected individuals will have problems with ventilation and external respiration. | Ans:|Answers could include: reduced compliance (reduces ability to increase thoracic volume); increased airway resistance (decreases tidal volume); decreased diffusion due to increased diffusion distance, decreased surface area, and changes in partial pressures of gases (altering gradients). Other answers may be acceptable.  Human A&P CH. 22 Respiratory System Essay.
