the initial stage of blood filtration in the kidneys occurs in the proximal tubules portion of the nephron.
the initial stage of blood filtration in the kidneys occurs in which portion of the nephron?
proximal tubules
some diseases of the nephron predominantly affect either the glomeruli or the tubules. glomerular diseases include diabetic nephropathy, glomerulonephritis and iga nephropathy; renal tubular diseases include acute tubular necrosis and polycystic kidney disease.

the nephron is the functional unit of the kidney. each nephron is composed of a renal corpuscle, the initial filtering component; and a renal tubule that processes and carries away the filtered fluid.

the renal corpuscle is the site of the filtration of blood plasma. the renal corpuscle consists of the glomerulus, and the glomerular capsule or bowman's capsule.
nephron
this system is especially significant in the kidneys, where the glomerular filtration rate (the rate of blood filtration by the nephron) is particularly sensitive to changes in blood pressure. however, with the aid of the myogenic mechanism, the glomerular filtration rate remains very insensitive to changes in human blood pressure.
