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.
Antidiuretic hormone stimulates water reabsorbtion by stimulating insertion of water channels or aquaporins into the membranes of kidney tubules. These channels transport solute-free water through tubular cells and back into blood, leading to a decrease in plasma osmolarity and an increase osmolarity of urine.ffects on the Kidney. The single most important effect of antidiuretic hormone is to conserve body water by reducing the loss of water in urine. A diuretic is an agent that increases the rate of urine formation.
