WebThe pedicels interdigitate to form filtration slits, leaving small gaps that form a sieve. As blood passes through the glomerulus, 10 to 20 percent of the plasma filters out of the fenestrations, through the basement membrane and between these sieve-like fingers to be captured by the glomerular capsule and funneled to the PCT. WebPurpose of review: The podocyte slit diaphragm is probably the least understood component of the kidney filtration barrier. In this review, we aim to integrate the most …

WebNFP determines filtration rates through the kidney. It is determined as follows: NFP = Glomerular blood hydrostatic pressure (GBHP) – [capsular hydrostatic pressure (CHP) + blood colloid osmotic pressure (BCOP)] = 10 mm Hg That is: NFP = GBHP – [CHP + BCOP] = 10 mm Hg Or: NFP = 55 – [15 + 30] = 10 mm Hg WebDiagram of the circulation related to a single glomerulus, associated tubule, and collecting system The renal corpuscle in the cortex (outer layer) of the kidney.
