Unformatted text preview: the Loop of Henle. What is the function? consists of: 1.Thin Limb: descending (PEREIABLE to H20; NOT TO SOLUTES!) 2.Thick Limb: ascending (IMPERMEABLE to H20 & SOLUTES!) ACTIVE TRANSPORT moves Na & Cl out of filtrate to peritubular fluid; H20 pulled out of thin limb. What is Countercurrent multiplication? (It moves against each one another) Greater solutes in peritubules due to the active transport moving out the Na & Cl cause for increased effect of H20 being reabsorbed than the thin limb could offer by itself. Osmosis!!! Describe the function of the Distal Convoluted Tubule. Main function is SECRETION: drugs, ions, toxins, K+, H+ (it is here where the body pH is determined) Reabsorption: Na+ into blood in exchange for K+ into filtrate What two hormones affect reabsorption & secretion at the collecting ducts. Aldosterone (produced in the adrenal gland)& ADH (antidiuretic hormone) (made in hypothalamus & stored in pituitary) What is reabsorbed and secreted by the Collecting ducts? reabsorption of Na+ So then H20 follows secretion of H+ and HC03- (absorbed or secreted to maintain blood pH) Function of Aldosterone targets collecting ducts by encouraging reabsorption of Na+ Function of ADH targets collecting ducts by helping to concentrate...
