WebH+ secretion con tinues in the distal nephron but does not appear to be coupled with Na+ reabsorption. Distal nephron H+ secretion is primarily an active process and occurs in the intercalated cells of the collecting duct. Renal K+ transport is unique in that it is reabsorbed in some parts of the tubule and secreted in others. WebThe other segments have thicker cells with a brush border and are rich in mitochondria to facilitate active and passive mechanisms of tubular reabsorption and tubular secretion.

WebNov 11, 2024 · The majority of nephron secretion takes place in the medulla via the Henle loop, which is located there. This section of the nephron is responsible for producing creatinine and urea.
