- How do Na-H exchangers on the luminal surface of tubular cells promote bicarbonate reabsorption in the renal tubules?What are the mechanisms by which sodium depletion causes an increase in renin secretion?Why are more phosphate ions required in the ICF than inthe ECF? How does this affect the distribution of calciumions between these fluid compartments?
- How does ADH affect urine volume? How does ADH affect urine solute concentration ?Renin is secreted in response to hypovolemia or to an increase in the osmolality of the blood. Provide three possible mechanisms by which these conditions may stimulate rennin secretion. What are the consequences of increased rennin secretion that lead to increased aldosterone secretion? Present this sequence of events. Why are angiotensin converting enzyme inhibitors (ACEIs) used as a common therapy for hypertension? How do they influence blood pressure?
