Distal convoluted tubule: Anatomy and function - Kenhub
2024年2月29日 · The distal convoluted tubule (DCT) is the tortuous, final segment of the renal tubule of the nephron, situated between the nephron loop (of Henle) and the connecting tubules. It is located within the cortex of the kidney, and is a direct continuation of the distal straight tubule (a.k.a. thick ascending limb of nephron loop). Numerous DCTs from ...
Distal convoluted tubule - Wikipedia
The distal convoluted tubule (DCT) is a portion of kidney nephron between the loop of Henle and the collecting tubule. It is partly responsible for the regulation of potassium, sodium, calcium, and pH. On its apical surface (lumen side), cells of the DCT have a thiazide-sensitive Na-Cl cotransporter and are permeable to Ca, via the TRPV5 channel.
Kidney histology: Nephron, loop of Henle, functions | Kenhub
2023年10月30日 · The straight distal tubule (thick ascending limb) continues on from the thin ascending limb of the nephron loop at the level between the inner and outer medulla. The convoluted distal tubule projects into the cortex. Both parts of the distal tubule are composed of simple cuboidal epithelium, similar in morphology to the proximal tubule.
Distal Convoluted Tubule and Collecting Duct
2023年8月22日 · The distal convoluted tubule (DCT) and collecting duct (CD) are the final two segments of the nephron. They have an important role in the absorption of many ions and in water reabsorption. The distal convoluted tubule can be subdivided into early and late sections, each with its own functions.
Distal Convoluted Tubule - PMC
The distal convoluted tubule is the nephron segment that lies immediately downstream of the macula densa. Although short in length, the distal convoluted tubule plays a critical role in sodium, potassium, and divalent cation homeostasis. Recent ...
Role of Distal Convoluted Tubule in Kidney Function - iCliniq
2023年3月6日 · The distal convoluted tubule is a short but crucially important kidney nephron segment. It is critical in sodium, potassium, magnesium, and divalent cation regulatory mechanisms. The two segments of the distal convoluted …
The Distal Convoluted Tubule - PMC - PubMed Central (PMC)
The distal tubule of the mammalian kidney can be defined as the nephron segment between the macula densa region and the cortical collecting tubule. It comprises several morphologically and functionally heterogeneous subsegments, reabsorbs 5–10% of the filtered sodium and chloride under normal conditions, and participates importantly in net K ...

2023年7月24日 · Three different sets of kidneys develop consecutively from the urogenital ridges, and the last set persists to become the adult kidney. The first renal tubular system is called the pronephros. Pronephros develop during the fourth week of embryonic development but quickly degenerates as mesonephros appears.
25.4 Microscopic Anatomy of the Kidney - OpenStax
At the juncture where the afferent and efferent arterioles enter and leave Bowman’s capsule, the initial part of the distal convoluted tubule (DCT) comes into direct contact with the arterioles. The wall of the DCT at that point forms a part of the JGA known as the macula densa.
