In other words, a juxtamedullary nephron is a nephron whose renal corpuscle is near the medulla, and whose proximal convoluted tubule and its associated loop of Henle occur deeper in the medulla than the other type of nephron, the cortical nephron. The juxtamedullary nephrons comprise only about 15% of the nephrons in the human kidney.
Loop of Henle. In the kidney, the loop of Henle (English: / ˈhɛnli /) (or Henle's loop, Henle loop, [1] nephron loop[2] or its Latin counterpart ansa nephroni) is the portion of a nephron that leads from the proximal convoluted tubule to the distal convoluted tubule. Named after its discoverer, the German anatomist Friedrich Gustav Jakob ...
Function. Diagram outlining movement of ions in nephron, with the collecting ducts on the right. The collecting duct system is the final component of the kidney to influence the body's electrolyte and fluid balance. In humans, the system accounts for 4–5% of the kidney's reabsorption of sodium and 5% of the kidney's reabsorption of water.
In the renal system, peritubular capillaries are tiny blood vessels, supplied by the efferent arteriole, that travel alongside nephrons allowing reabsorption and secretion between blood and the inner lumen of the nephron. Peritubular capillaries surround the cortical parts of the proximal and distal tubules, while the vasa recta go into the ...
Note 2: Also called the cortical radiate arteries. The interlobular artery also supplies to the stellate veins. Note 3: The efferent arterioles do not directly drain into the interlobular vein, but rather they go to the peritubular capillaries first. The efferent arterioles of the juxtamedullary nephron drain into the vasa recta.
Metanephrogenic blastema. Identifiers. Latin. tubulus contortus distalis. FMA. 17721. Anatomical terminology. [edit on Wikidata] The distal convoluted tubule (DCT) is a portion of kidney nephron between the loop of Henle and the collecting tubule.
The proximal tubule is the segment of the nephron in kidneys which begins from the renal pole of the Bowman's capsule to the beginning of loop of Henle. At this location, the glomerular parietal epithelial cells (PECs) lining bowman’s capsule abruptly transition to proximal tubule epithelial cells (PTECs). The proximal tubule can be further ...
Interlobular arteries. Scheme of renal tubule and its vascular supply. Cortical radial arteries, formerly known as interlobular arteries, [1] are renal blood vessels given off at right angles from the side of the arcuate arteries looking toward the cortical substance. The interlobular arteries pass directly outward between the medullary rays to ...
