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.
Role of Hormones Antidiuretic hormone (ADH): Controls reabsorption of water in the blood. (more ADH, more water reabsorption) Made in the hypothalamus but stored in and released from the pituitary gland in the brain. Increases the permeability of the walls of the distil tubules and collecting ducts to water.t is produced in the hypothalamus and secreted from the posterior pituitary gland. Aldosterone increases the reabsorption of sodium ions into the blood in the loop of Henle and distal tubes.
