Summary Introduction

To determine: The two-solute models that enable the production of hyperosmotic urine.

Introduction: The hyperosmotic urine is the urine that contains more amount of solutes and less amount of water in it. The kidney can produce a maximal urine concentration of about 1200 to 1400 mOsm/L. When there is deficient of water in the bod the hypothalamus releases the anti-diuretic hormone which increases the expression of aquaporin in the renal lumen that results in the absorption of water from the filtrate that results in the formation of hyperosmotic urine.

One type of diuretic given to people with high blood pressure, renal disease and congestive heart failure are thiazide-type diuretics. These drugs inhibit sodium ion reabsorption by inhibiting the transport in the ascending limb of the loop of Henle. A) What does it mean to inhibit the transport of sodium ions in the loop of Henle? B) Explain how this inhibition of sodium ions in the loop of Henle could help increase urine production.
Active transport requires the use of ATP.  Identify two ions that require active transport to be selectively reabsorbed.
When the kidneys filter plasma, the filtered glucose is reabsorbed from the renal tubules and is not passed in the urine. However, glucose can appear in the urine when the blood sugar is exceptionally high.   Given that glucose is reabsorbed by carrier-mediated transport, what functional aspect of carrier-mediated transport does the appearance of glucose in urine demonstrate? Explain.
