Document Summary
Renal corpuscle pressure to push the fluid into the capsule. Renal tubule reconnect lost material with blood stream (reabsorption and secretion) Renal tubule & collecting duct (urine making machine) Urine goes out to the ureters and then the bladder. Secretion of material from the blood to the tubule. Reabsorption of material from the filtrate in the tubule to the blood. 180 l of water in filtrate but 1-2 liters of urine. 162 g of glucose in the filtrate but none in the urine. 2. 0 g of protein in the filtrate 0. 1 g excreted if too much protein is excreted kidneys aren"t functioning. Descending limb of loh lets water out, water permeable. Ascending limb of loh impermeable to water. Collecting duct variably permeable to water (if theres a lot of holes (cid:0) lots of urine) Arcuate arteries afferent arteriole comes off of this artery: all blood for a nephron is individual. Veins - pick up blood (cid:0) dumps into arcuate vein.
