Cards in this set: Term Can Angiotensin II cause the release of Aldersterone from the adrenal cortex? Definition Yes Term When Angiotensin Ii releases aldosterone, wht is reasorbed and what is secreted? Definition 100% Reabsorption of Na+, Water follows, and Secretion of K+ or H+ Term Can The Thirst center in hypothalmus be timulated by Angiotensin II releasing Aldosterone? Definition Yes, thirst center in hypothalmus is stimulated to increase blood volume Term Can Angiotensin II cause the release of ADH? Definition Yes Term What happens to the Efferent arterioles and smooth muscle cells when Angiotensin II causes the release of ADH? Definition Efferent artioles- vasocontriction which increases GFR Smooth muscle cells- constrict to increase blood pressure which increases GFR Term What happens in Tubular Reabsorption? Definition 99% of filtrate is returned to blood stream Term Which tube is responsible for the majority of reabsorption? Definition Proximal Convoluted Tubule containing microvilli Term Which tubule fine tunes reabsorption? Definition Distal Convoluted Tubule Term Which capillaries are involved in tubular reabsorption? Definition Vasa Recta and Peritubular Capilaries Term Where are the Peritubular Capillaries? Definition Around PCT and DCT Term Where are the Vasa Recta capillaries Definition Around Loop of Henle Term What is solvent drag? Definition Water leaving increases concentrations of K, Cl, HCO3-, and urea Term With Na+ reabsorption, what is it called when water follows salt? Definition Osmosis Term Where is glucose, amino acids, lactic acid, and other metabolites reabsorbed? Definition In PCT Term With regard to glucose, what is a Tm- transport maximum? Definition A symporter has a miximum amount for transport measured so if a substance is above Tm, it gets urinated Term What is Glucosuria? Definition Maximum blood glucose which can be completely reabsorbed = 120 mg/mL normal blood glucose level is 70 to 110 mg/mL Term What is a protein transporter that moves 2 substances in the same direction? Definition Symporter Term What process removes materials from blod and adds to the filtrate- most common are K+, H+ and NH4+? Definition Tubular secretion Term What does tubular secretion do? Definition Removes materials from blood and adds to the filtrate Term How is ammonia NH3 formed? Definition From deamination of amino acids in the liver Term How is NH4+ formed? (ammonium) Definition NH3 combines with H+ in the plasma Term If pH > 7.45, what happens to ammonia production Definition DECREASES amonia production in Alkalosis Term If pH<7.35, what happens to ammonia production? Definition INCREASES IN ACIDOSIS Term What is formed from Deamination reactions? Definition Urea Term What happens to pH when Nh3 + H =NH4? Definition Increases pH
