WebUltrafiltration begins in the nephron in the kidney. Blood travels through a coiled structure of capillaries called the glomerulus surrounded by the Bowman's capsule. The hydrostatic pressure of the flow of bloods allows small molecules within the blood to pass through the capillary membrane and through the gaps in the podocytes surrounding the ... WebEach of these carries out a specific function. The proximal nephron absorbs about two-thirds of filtered sodium, without dissociating salt and water absorption. The thick ascending limb absorbs 25% of filtered Na+, but no water. The distal nephron absorbs 10% of filtered Na+ in close relation with K+ and, to some extent, H+ secretion.
