Tubular secretion occurs at Proximal Convoluted Tubule (PCT) and Distal Convoluted Tubule (D.C.T); for example, at proximal convoluted tubule, potassium is secreted by means of sodium-potassium pump, hydrogen ion is secreted by means of active transport and co-transport, i.e. anti-porter, and ammonia diffuses into renal tubule.
The proximal tubule efficiently regulates the pH of the filtrate by secreting hydrogen ions (acid) into the tubule and reabsorbing approximately 80% of the filtered bicarbonate. [6] Fluid in the filtrate entering the proximal convoluted tubule is reabsorbed into the peritubular capillaries.
Firstly, the glucose in the proximal tubule is co-transported with sodium ions into the proximal convoluted tubule walls via the SGLT2 cotransporter. Some (typically smaller) amino acids are also transported in this way. Once in the tubule wall, the glucose and amino acids diffuse directly into the blood capillaries along a concentration gradient.
Convoluted tubule is the compound of a metanephridium which is wrapped with capillaries. It is highly coiled so as to increase surface area for more effective reabsorption, which occurs in this part of the metanephridium. The distal tubule of the mammalian kidney is the portion of the nephron located between the macula densa region and the ...
Reabsorption of HCO 3 − occurs in the proximal tubule, in the ascending limb of the loop of Henle, and to a lesser extent in the distal convoluted tubule of the nephron. H + secretion is carried out mainly through Na + /H + exchangers in the tubules of the nephron. [150] The collecting ducts are involved in the energy-dependent secretion of H ...
The collecting duct system of the kidney consists of a series of tubules and ducts that physically connect nephrons to a minor calyx or directly to the renal pelvis.The collecting duct participates in electrolyte and fluid balance through reabsorption and excretion, processes regulated by the hormones aldosterone and vasopressin (antidiuretic hormone).
The distal convoluted tubule has a different structure and function to that of the proximal convoluted tubule. Cells lining the tubule have numerous mitochondria to produce enough energy for active transport to take place. Much of the ion transport taking place in the distal convoluted tubule is regulated by the endocrine system.
