Diuretics are sometimes used to treat hypertension. Explain what a diuretic is, and how
it can help reduce blood pressure.
Patients with kidney disease lose plasma albumin in their urine. This loss of plasma proteins may lead to edema in these patients’ tissues. Use what you know about capillary filtration and reabsorption to explain why this edema occurs. The answer must include an explanation of what edema is.
Compare and contrast the functions of the kidneys and the heart using a table. If both were candidates running for the presidential elections inside your body, which one would choose and why? If you do not want to vote for either the heart or the kidney, which organ would you vote for and why? Think of a way to make your reason more substantial by considering the role of both the heart and the kidneys in blood pressure regulation.

- Hypertension is a major health issue in the United States, yet glomerular filtration rate is not autoregulated until mean arterial blood pressure exceeds 180 mm Hg. In contrast, a drop in mean arterial blood pressure of only a few mm Hg sets autoregulation into motion.
