Some animals excrete uric acid in urine (uricotelic) as it requires very little water. This is an adaptation to conserve water loss. Which animals among the As terrestrial animals have to conserve water they use this mode of excretion where they pass dilute solution uric acid into the cloaca and water is absorbed and solid uric acid is

•Urine is much more concentrated than blood •The cooperative action and precise arrangement of the loops of Henle and collecting ducts are largely responsible for the osmotic gradient that concentrates the urine •NaCl and urea contribute to the osmolarity of the interstitial fluid, which causes reabsorption

Excretion of dilute urine requires ________. a) the presence of ADH. b) transport of sodium and chloride ions out of the descending loop of Henle. c) impermeability of the collecting tubule to water. d) relative permeability of the distal tubule to water. c) impermeability of the collecting tubule to water.

requires less water to dilute and flush from the body The primary nitrogenous waste product in mammal urine is urea. preferentially excreting water and retaining ions. Urine will be more dilute. If urine solute concentration is … 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.

EXCRETION IN MAN Main waste products are CO 2, H 2 O and urea. The main excretion organs are the skin, kidneys and the lungs. The skin excretes water, excess salt and urea inform of sweat. Kidney excretes excess water, excess salts, and urea as urine. Lungs excrete CO 2 and H 2 O (g) in exhaled breath. Carbon dioxide.

The excretion product of the kidneys is known as urine. requires less water to dilute and flush from the body The primary nitrogenous waste product in mammal urine is urea. preferentially excreting water and retaining ions. Urine will be more dilute. If urine solute concentration is … 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 • Sodium and Water Physiology Consider water and Na separately as regulation is independent ECF Na + Na + content ECF volume Na + concentration … EXCRETION IN MAN Main waste products are CO 2, H 2 O and urea.

In this case, the body would produce small volumes of concentrated urine. If the body is well hydrated, less water will be reabsorbed from the urine and the body will produce larger volumes of dilute urine. Two essential hormones drive this process 1. Expert Answer. 22) The correct option is B. impermeability of the collecting tubule to water.

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 Excretion of dilute urine requires. 1. relative permeability of the distal tubule to water. 2.

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 […]

The defect in the production of ADH results in the excretion of large quantities of dilute urine, this is called Diabetes insipidus. This results in the dehydration and fall in blood pressure. Question 14. What is Micturition? Answer: The process of release of urine from the bladder is called micturition or urination.
