Document Summary
Physiology 335 lab 9 pre-lab recording (renal and acid-base balance) First part of lab will focus on renal physiology. Second part will focus on acid base balance (which is regulated both by respiratory and renal system. Renal physiology: know anatomy of nephron and directionality of flow in tubules, filtrate is pre-urine, moves through nephron and goes through different processes. Secretion: when filtrate exits the collecting duct (not at the end of the tube but through the tu(cid:271)e wall), it"s (cid:272)alled ex(cid:272)retion filtrate formation does not go through excretion. Urine analysis what are the factors that form filtrate (which ends up being urine): at the renal corpuscle starling forces (similar to cardio phys) Nf = filtration reabsorption: glomerular filtration rate (gfr): volume of fluid filtered (bulk flow) from the gc to the bs per time) Everything from glomerular capillary is originally being filtered except the large and charged proteins. Increase v increase map increase (cid:3004) increase gfr .
