Diabetes insipidus (DI) is a condition characterized by large amounts of dilute urine and increased thirst. The amount of urine produced can be nearly 20 liters per day. Reduction of fluid has little effect on the concentration of the urine. Complications may include dehydration or seizures.

dilute urine Salts lost by Conversion of ammonia to urea is energetically expensive; excretion of urea requires less water than ammonia Uric Acid Insects, land snails, and many reptiles, Metanephridia consist of tubules that collect coelomic fluid and produce dilute urine for excretion Malpighian tubules the urine is more concentrated than plasma, which requires the presence of the antidiuretic hormone, vasopressin. Therefore, hyponatremia means a dis-turbance of water balance. Water excretion by the kidney is guided by the hypothalamic antidiuretic hormone, arginine vaso-pressin. The hormone is normally released from the requires metabolic energy to build (as opposed to ammonia) contains two nitrogen atoms; is less toxic than ammonia requires less water to dilute and flush from the body exreted by a wide variety of animals, both aquatic and terrestrial The primary nitrogenous waste product in mammal urine is urea.

Loop of Henle. Proximal tubule. Check Answer. TNPSC - Easy Tutorial. The urinary system not only controls the body's fluid balance and rids the After all of the tubular secretion and reabsorption is complete, the final product, urine, Which of the following is responsible for excretion of dilute urine ?

the presence of ADH. 4.

Excretion of dilute urine requires _____. A) the presence of ADH B) relative permeability of the distal tubule to water C) impermeability of the collecting tubule to water D) transport of sodium and chloride ions out of the descending loop of Henle

We took advantage of 24-hour urine collection to examine both urine protein/creatinine ratio (UPCR) and daily urine protein excretion, with the latter as the Excretion of dilute urine requires 93 A relative permeability of the distal from BSC 2086 at St. Johns River State College The more ADH is present in the blood, the more water is reabsorbed into it. This happens because the presence of ADH in the blood causes the cells in the last section of the DCT to become more permeable to water, therefore they allow more water to pass from the tubular fluid back into the blood. This results in more concentrated urine. into play to reabsorb water from the urine to add to the blood.

Serum sodium concentration and serum osmolality that are low and urine osmolality that is inappropriately high (120 to 150 mmol/L [120 to 150 mOsm/kg])) with respect to the low serum osmolality suggest volume overload Excretion of salt ions and large amounts of water in dilute urine from kidneys Water Salt Key Freshwater fish are hyperosmotic to sea water and thus will gain water and lose salt. To counter this freshwater fish: • excrete large amounts of water from the kidneys • uptake salt in the gills • ADVERTISEMENTS: The normal kidney has tremendous capability to vary the relative proportions of solutes and water in the urine. They can excrete urine with an osmolarity as low as 50 mOsm/L, when there is excess water in the body and ECF osmolarity low. They can also excrete urine with a concentration of 1200-1400 mOsm/L, when […] On a typical Western diet providing 900 milliosmoles of solute daily, a maximally concentrated urine reduces daily urine volume to 0.75 L. A maximally dilute urine allows excretion of 18 L of urine, providing a robust defense against both dehydration and the development of hyponatremia.

Specific gravity determines the concentration of urine – it compares water content to the number of substances in the urine. Regular urine has a specific gravity between 1.002 and 1.030. Urine with a specific gravity between 1.001 and 1.003 is considered The usual causes of this state are damaged kidneys, which make no effort to reabsorb sodium, and which fail to respond normally to ADH. Thus sodium excretion continues in spite of low sodium, and the urine remains dilute in spite of the fact that there may be hypovolemia. Your kidneys are normal, and they are trying to dump dilute urine, but you just keep on taking on more and more fluid, either because you are insane, or the doctor gave you 10 bags of 5% dextrose.

This region is responsible for concentration and dilution of urine by utilising a revealed at higher rates of solute excretion. As will be absen t and yet concentrated urine will be excreted.
