Respuesta :
The single most important factor influencing potassium ion secretion is potassium ion concentration in blood plasma.
Define renal secretion.
The renal tubule, where nutrients and water are reabsorbed into capillaries, receives the filtrate that the glomerulus absorbed. The renal tubule receives both waste and hydrogen ions at the same time from the capillaries. Secretion is the name for this procedure.
Processes for proper distribution of potassium between intracellular and extracellular fluid compartments as well as mechanisms for kidney excretion are all part of the regulation of potassium metabolism. The collecting duct and late distal collecting tubule (DCT) are the main sites where potassium is secreted. Long-term serum potassium level regulation is the aim of secretion.
The rate of secretion varies and can be accelerated or slowed down by a number of factors .The substantial secretion with a normal or high K+ diet ranges between 15-20%. However, very little secretion occurs with a low K+ diet or depletion.
