Which of the following mechanisms controls RBF? a. intrinsic b. autoregulation c. extrinsic d. protein & glucose e. sympathetic controls a, c, d Intrinsic, extrinsic and protein and glucose Which of the following PASSIVELY diffuses in the nephron tubules? a. sodium b. glucose c. water d. potassium e. chloride f. urea g. phosphate h. calcium I. amino acids c, f water and urea Which of the following ACTIVELY diffuses in the nephron tubules? a. sodium b. glucose c. water d. potassium e. chloride f. urea g. phosphate h. calcium I. amino acids a, b, d, e, g, h, I sodium (Na+), glucose, potassium (K+), chloride (Cl-), phosphate (PO4+), calcium (Ca2+), amino acids The "diluting segment" is another name for this part of the Loop of Henle a. thin descending limb b. thin ascending limb c. thick ascending limb b. thin ascending limb Which electrolyte concentration is higher INSIDE the cell? a. sodium b. potassium c. calcium d. chloride b – potassium Which electrolytes concentration is higher OUTSIDE the cell? a. sodium b. potassium c. calcium d. chloride a, c - sodium and calcium "Solutes reabsorbed, but water CANNOT follow -- filtrate becomes DILUTE" describes which part of the Loop of Henle? a. thin descending limb b. thin ascending limb c. thick ascending limb b. thin ascending limb "Reabsorption of Na/ K/ Cl occurs by ACTIVE transport" happens in this segment of the Loop of Henle a. thin descending limb b. thin ascending limb c. thick ascending limb c. thick ascending limb In the collecting tubule ______ is secreted when ______ is reabsorbed a. sodium b. chloride c. calcium d. potassium d, a potassium is secreted when sodium is reabsorbed Which hormone is responsible for potassium secretion and sodium reabsorption in the collecting tubule? a. ADH b. angiotensin c. aldosterone d. epinephrine c. aldosterone ex: person who is dehydrated -- more concentrated urine because more WATER is reabsorbed Where do anti-aldosterone diuretics work? a. collecting tubule b. proximal convoluted tubule c. thick ascending limb d. collecting tubule a. collecting tubule "potassium sparing" Cellular dehydration describes what sodium imbalance? a. hypertonic hyponatremia b. hypervolemic hyponatremia c. hypernatremia c. hypernatremia
