Document Summary
Have primary cilia: (allow them to detect fluid flow; how fast it"s flowing(cid:524) Juxtaglomerular cells (granular cells): compose a part of the afferent arteriole. Respond to the signals from macula densa cells. Clinical note: urinalysis: overall health of the body can be quickly assessed by measuring components of urine, test strips with colorimetric reactions have been developed to indicate substances in the urine. & apoptosis (lose a number of functional nephrons: too little (filtrate is too slow) the day, the glomerular filtration rate (gfr) is due to the net of the forces in the corpuscle, 125 ml/min is filtered per day. Bowman"s space: doesn"t usually exist in healthy kidneys, fluid is filtered, pressure created due to the presence of proteins in the fluid (filtrate) in. Net filtration = (pgc + bc) (pbc + gc) Force promoting filtration force inhibiting filtration: net filtration = 10 mmhg (allow you to filter 180l of blood/day, higher than this = more filtration.
