- Diuretics can be prescribed to combat high blood pressure. Thiazide is one of the most common. Describeits mechanism of action (they physiology of what the drug does) and how it combats high blood pressure.
- The action of the diuretic Thiazide can also cause the activation of the renin-angiotensin system. Explain this system (starting with renin) and whyit would be counterproductive to the reason you prescribed Thiazide for a patient.

Vasomotion can also be altered. Automatic…arrow_forwardWhich of the following is correct about chloride reabsorption from the loop of Henle? Group of answer choices A.
