Document Summary
Note that thick ascending limb of loop of henle is really close to bowman"s capsule. Glomerulus is able to check composition of urine here to see if its correct. Lumen of bowman"s capsule (bowman"s space) collects the first filtered urine. Filtration slit: allows material to leak through into lumen of bowman"s capsule. Glomerular filtration rate (gfr): volume of plasma filtered by the glomerulus per unit time. If you don"t meet a certain gfr your kidneys will not function. Glomerular blood flow: rate of blood flow through glomerulus. Plasma glomerular flow: rate of plasma flow through the glomerulus. Filtration fraction: proportion of plasma filtered by the glomerulus. Hydrostatic pressure in glomerulus capillaries (not bowman"s capsule. This would be the hydrostatic pressure in interstitial fluid in capsule) In kidney its higher cos you need to filter. A decrease in map from 85mmhg to 60mmhg.
