Detailed explanation-1: -After reabsorption of K+ along the proximal tubule and loop of Henle, approximately 10% of filtered K+ reaches the DCT. As fluid travels down the DCT, the luminal potassium concentration increases, indicating that net K+ secretion occurs along the distal tubule.
Detailed explanation-2: -Passing through the DCT, the filtrate enters the collecting ducts. Further reabsorption of water takes place in the collecting ducts. 3. Tubular secretion-Secretion is the final step in the formation of urine.
Detailed explanation-3: -The distal convoluted tubule (DCT) is a short nephron segment, interposed between the macula densa and collecting duct. Even though it is short, it plays a key role in regulating extracellular fluid volume and electrolyte homeostasis.
