Some people are very sensitive to flea bites -- but scratching can cause a wound or infection. The best solution is to get rid of fleas on pets and in your home. Keep pets out of your bed and be sure to vacuum rugs daily. Spray insecticides according to directions on infested areas.
Antidiuretic hormone binds to receptors on cells in the collecting ducts of the kidney and promotes reabsorption of water back into the circulation. In the absense of antidiuretic hormone, the collecting ducts are virtually impermiable to water, and it flows out as urine. Antidiuretic hormone stimulates water reabsorbtion by stimulating insertion of water channels or aquaporins into the membranes of kidney tubules.
RE: What is the function of urea reabsorption in the collecting ducts of the kidney? Answers to chose from; A) It restores the correct concentration of blood urea.B) It increases the osmotic concentration of the interstitial fluid in the renal medulla so that more water can be extracted from the urine.C) It reduces the salinity of the renal medulla and thus helps regulate how much water is reabsorbed from the urine.E: What is the function of urea reabsorption in the collecting ducts of the kidney? Answers to chose from; A) It restores the correct concentration of blood urea.
