Name and curtly describe the deuce-ace basic processes of respiration. Ans1. Pulmonary ventilation is the campaign 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 exhalation58. expose the inward forces of elastic confine, and explain why the lungs do not commonly collapse during expiration. AnsElastic recoil is the recoil of elastic fibers stretched duri ng inspiration and the pull of the surface tension of alveolar fluid. Intrapleural pressure is always subatmospheric during formula breathing, which tends to pull lungs outward and to keep alveolar pressure from equalizing with atmospheric pressure. bedwetter in alveolar fluid decreases surface tension to help prevent collapse.

Using decorous respiratory system terminology, explain at least four reasons why affected individuals depart have problems with ventilation and external respiration. AnsAnswers could entangle reduced compliance (reduces ability to increase thoracic volume) increased airway resistance (decreases tidal volume) decreased diffusion due to increased dif fusion distance, decreased surface area, and changes in partial pressures of gases (altering gradients).

Name and briefly describe the three basic processes of respiration. Ans1. 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.

Describe the inward forces of elastic recoil, and explain why the lungs do not normally collapse during expiration. AnsElastic 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 Respiration59.

Using proper respiratory system terminology, explain at least four reasons why affected individ uals will have problems with ventilation and external respiration. AnsAnswers 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).
