drugs known as potassium-sparing diuretics work by blocking the effects of aldosterone on the kidney. what effect would these drugs have on the amount of urine produced, on the blood pressure, and on potassium ion concentration in the blood? could these drugs have a negative impact on the acid-base balance of the body? explain.
What are the physiological implications of excreting waste nitrogen in the form of urate, urea, or ammonia?
The renal handling of a novel drug is being studied. When the drug is present in the blood, it is filtered into the Bowman’s capsule and secreted via transport proteins in the renal tubules, but it is NOT reabsorbed. The lines on the following graph represent filtration, secretion and excretion rates of this drug at various plasma concentrations. For the three lines shown (labeled A-C) identify which line represents filtration, which line represents secretion, and which line represents excretion Explain how you determined this.
Atrial Natriuretic Peptide helps to reduce overall blood pressure in a variety of ways. One way is by increasing Glomerular Filtration Rate. a. Why/how would increasing GFR cause decreased blood pressure? b. To increase GFR, would Atrial Natriuretic Peptide cause constriction or dilation of afferent arterioles at the kidneys? The efferent arterioles?
