Summary Introduction

To determine: Whether the higher glucose concentration in blood than it can be reabsorbed in the kidney would result in loss or gain of water.

Introduction: Maintenance of osmotic balance in tissues is essential to perform different metabolic functions. Osmoregulation and maintenance of body fluid levels ensure proper thermoregulation, sufficient organ perfusion, electrolyte balance, and excretion of wastes. The loop of Henle is present with nephrons in birds and mammals. Hypertonic urine production is achieved by the loop of Henle part of the nephron. In the loop of Henle, water and monovalent ions like Cl- and Na+ are reabsorbed.

Explanation of Solution

Reabsorption refers to the selective movement of solutes, like amino acids, glucose, and several other inorganic ions, from the filtrate present in the tubules system to the body fluids. Further, they move back into the blood stream through surrounding peritubular capillaries. Reabsorption of water also occurs and this process can be controlled for regulating the extent of water loss. When the glucose concentration is about 180 mg/100 mL in blood, saturation occurs. In untreated diabetes mellitus, the glucose concentration in blood exceeds this quantity. The glucose molecules that remain in the glomerular filtrate are then eliminated in the urine. An increase in the quantity of glucose in the blood would decrease the quantity of water that is reabsorbed, thus ultimately resulting in the loss of water.

Glucose is normally 100% reabsorbed, such that no glucose is excreted in the urine. Explain why a person with diabetes and a blood glucose level of 450 mg/dL will have glucose excreted in his urine.
During a state of low blood volume and decreased extracellular sodium level (as in cardiac failure), which one of the following occurs? 1)  B. Aldosterone is produced by the kidneys, leading to the release of renin, which increases kidney reabsorption of sodium. 2)  D. Antidiuretic hormone produced by the kidneys stimulates the production of aldosterone by the adrenal gland, which increases reabsorption of sodium and water retention. 3)  A. Renin is produced by the kidneys and is converted to angiotensin, which induces the secretion of aldosterone by the adrenal gland, which in turn increases reabsorption of sodium and retention of water. 4)  C. Renin is produced by the adrenal glands, leading to vasoconstriction and production of antidiuretic hormone by the pituitary gland, which increases fluid volume by causing water retention. no references, just homework
Explain how the nervous system and the excretory system have to work together to maintain water balance, including both dehydration and excess hydration. What would happen if the nervous system became damaged and could no longer send signals to stimulate the release of ADH ?
