A) peripheral chemoreceptors B) dorsal respiratory group of the medullary rhythmicity center C) ventral respiratory group of the medullary rhythmicity center D) pneumotaxic area 13 The respiratory membrane, across which gases diffuse, is very thin and is made up of _______________. A) alveolar macrophages and the alveolar cell membrane B) alveolar cell membrane and its basement membrane C) alveolar cell membrane and capillary membrane D) alveolar cell membrane, capillary membrane, and fused basement membranes 14 Whether oxygen diffuses from the alveoli into the blood or not is dependent upon _______________. A) the partial pressure of oxygen in the lungs and in the blood B) the partial pressure of oxygen in the lungs only C) the partial pressure of oxygen and carbon dioxide in the blood D) the partial pressure of all gases in the atmosphere and blood 15 Within the blood, oxygen is primarily transported __________________ while the bulk of carbon dioxide is transported _________________.
