Identify the organs of the urinary system and the major regions of the kidney on a diagram: kidneys, filter the blood of wastes and return most water and solutes to the bloodstream, regulation of blood ionic composition. Na, k, ca, cl and phosphate ions: regulation of. Blood volume: conserving or eliminating water. Blood pressure: secreting the enzyme renin, adjusting renal resistance. ~125ml total blood plasma is filtered by the kidneys every minute. ~180l of blood plasma is filtered by the kidneys each day. Physiological functions on blood: filtration, reabsorption, secretion, ureters, urinary bladder, urethra, 2. Secretion, filtration, and majority of reabsorption occurs: loop of henle. Ascending limb: salt reabsorption, distal convoluted tubule. ~5% of reabsorption occurs here: collecting duct. Aldosterone: absorbs all other solutes: 3. Lecture 30 urinary system- glomerular filtration: 1. List the components of the filtration barrier within the renal corpuscle: 1.
