Describe the homeostatic processes involved in the control of respiration, there are three elements that contribute to the regulation of ventilation. 4. Where are the “sensors” for oxygen? (there are several, find the ones that would be considered “peripheral”). 5. Where is the “thermostat”, or control center, that regulates your respiratory rate? 6. What are […]

Water receptor antagonists are not as effective as proton pump inhibitors at decreasing HCL concentrations in the stomach

Water receptor antagonists are not as effective as proton pump inhibitors at decreasing HCL concentrations in the stomach a. Acetylcholine and gastrin can still agonize their respective receptors stimulating proton pump activity b. The H2 receptor is coupled to GI thereby decreasing CAMP levels and ultimately proton pump protein expression C. None of these choices […]
