2017年11月24日 · PCT and DCT are the two convoluted parts of a nephron found in the renal cortex. PCT occurs after the Bowman’s capsule while DCT occurs after the loop of Henle. PCT is mainly involved in the reabsorption whereas secretion occurs in the DCT.

2024年1月22日 · The difference between PCT and DCT is that PCT performs reabsorption function in the nephron while DCT performs secretion function. We have further listed all of the vital distinctions and key points of PCT and DCT below:

2019年8月21日 · Proximal is permeable to many things, transports via diffusion. Not controlled by any major MCAT hormones. Distal is permeable to less things than proximal (no glucose or amino acids); usually varies the amount of water/urea reabsorbed.

The distal convoluted tubule (DCT) and proximal convoluted tubule (PCT) are both parts of the nephron, which is the functional unit of the kidney. However, they have distinct roles in the process of urine formation.

The DCT is lined with simple cuboidal cells, the distal convoluted tubule cells, that are shorter than those of the proximal convoluted tubule (PCT). The lumen appears larger in the PCT than the DCT lumen because the PCT has a brush border (microvilli).

2023年12月2日 · PCT (Proximal Convoluted Tubule) is the initial segment of the renal tubule; DCT (Distal Convoluted Tubule) is a later segment. Both play roles in urine formation and electrolyte balance.

2023年10月9日 · In this blog post, we will delve into the distinctive features of the PCT and DCT, exploring where electrolytes and salt are reabsorbed in the nephron. Furthermore, we will examine the reabsorption of glucose and other substances, as well as the reasons behind the coiled structure of the nephron.

Proximal convoluted tubule (PCT) refers to the convoluted segment of the nephron situated among Bowman’s capsule and the loop of Henle, whilst Distal convoluted tubule (DCT) refers to the convoluted portion of the nephron located seen …

2020年8月26日 · But to answer your question, yes the PCT is isotonic and the movement of solutes is through channels. The DCT, however, is hypotonic and this is a result of the extensive reabsorption that has occurred prior to urine reaching it. Hope this helped :) thank you.

Functions of DCT: 1. It maintains a proper concentration and pH of the urine. 2. Extra salts, ions of K +, Na +, Cl-and H + secrete from peritubular capillaries into DCT. 3. It secretes ammonium ions and hydrogen ions. 4. It is relatively impermeable to water but in …
