Edapt Mechanisms of Gas Exchange in the Lungs and Tissues quiz Anatomy and Physiology III with Lab-Holsey > Unit 7 In a closed system, the relationship between pressure and volume is best describe... d by _______. Charles’ law Boyle’s law Dalton’s law Ideal gas law Henry’s law What is the transport mechanism by which gases such as Oxygen and Carbon dioxide move across cell membranes? Simple diffusion Facilitated diffusion Secondary active transport Primary active transport Endocytosis Oxygen unloading occurs at the ___________. This process will ultimately ___________ the Oxygen partial pressure of the blood leaving this region. lungs; increase alveoli; determine tissues; increase tissues; decrease lungs; decrease Rank the following gases in the order of their solubilities in blood, from the least soluble to the most soluble. Carbon dioxide > Oxygen > Nitrogen Nitrogen > Carbon dioxide > Oxygen All three gases have equal solubilities in blood Oxygen > Carbon dioxide > Nitrogen Nitrogen > Oxygen > Carbon dioxide Which of the following is TRUE at the arterial end of the pulmonary capillaries? The partial pressure of Carbon dioxide is equal in the capillaries and in the alveoli. The partial pressure of Oxygen is higher in the capillaries than in the alveoli . The partial pressure of Oxygen is lower in the capillaries than in the alveoli. The partial pressure of Carbon dioxide is lower in the capillaries than in the alveoli. The partial pressure of Oxygen is equal in the capillaries and in the alveoli. Boyle’s law is associated with the relationship of pressure and volume, Henry’s law is associated with gas solubilities, and Dalton’s law is associated with gas mixtures and partial pressures. Respiratory gases cross the alveolar epithelium via _______. Primary active transport Facilitated diffusion Secondary active transport Osmosis Simple diffusion At the arterial end of a systemic capillary, rank the following structures from highest to lowest partial pressure of Oxygen. cells > capillaries > interstitial fluid The partial pressure of oxygen is equal in all three noted components. capillaries > interstitial fluid > cells interstitial fluid > capillaries > cells cells > interstitial fluid > capillaries [Show More]
