  2. Nephron - Wikipedia

    en.wikipedia.org/wiki/Nephron

    The nephron is the minute or microscopic structural and functional unit of the kidney.It is composed of a renal corpuscle and a renal tubule.The renal corpuscle consists of a tuft of capillaries called a glomerulus and a cup-shaped structure called Bowman's capsule.

  3. Collecting duct system - Wikipedia

    en.wikipedia.org/wiki/Collecting_duct_system

    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. At times of ...

  4. Kidney - Wikipedia

    en.wikipedia.org/wiki/Kidney

    The last step in the processing of the ultrafiltrate is excretion: the ultrafiltrate passes out of the nephron and travels through a tube called the collecting duct, which is part of the collecting duct system, and then to the ureters where it is renamed urine. In addition to transporting the ultrafiltrate, the collecting duct also takes part ...

  5. Proximal tubule - Wikipedia

    en.wikipedia.org/wiki/Proximal_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).

  6. Mammalian kidney - Wikipedia

    en.wikipedia.org/wiki/Mammalian_kidney

    The nephron is composed of a renal corpuscle and a renal tubule. The renal corpuscle is a blood-filtering part of the nephron and is located in the cortex. The renal tubule extends from the renal corpuscle to the medulla into the loop of Henle and then returns back to the cortex. Finally, the renal tubule flows with its distal end into its ...

  7. Juxtaglomerular apparatus - Wikipedia

    en.wikipedia.org/wiki/Juxtaglomerular_apparatus

    The juxtaglomerular apparatus (also known as the juxtaglomerular complex) is a structure in the kidney that regulates the function of each nephron, the functional units of the kidney. The juxtaglomerular apparatus is named because it is next to (juxta-[1]) the glomerulus.

  8. Renal corpuscle - Wikipedia

    en.wikipedia.org/wiki/Renal_corpuscle

    Diagram of the circulation related to a single glomerulus, associated tubule, and collecting system The renal corpuscle in the cortex (outer layer) of the kidney. At the top, the renal corpuscle containing the glomerulus. The filtered blood exits into the renal tubule as filtrate, at right. At left, blood flows from the afferent arteriole (red ...

  9. Kidney (vertebrates) - Wikipedia

    en.wikipedia.org/wiki/Kidney_(vertebrates)

    Each nephron is located in both the cortex and the medulla. The most proximal part of the nephron is glomerulus, which is located in the cortex. [28] The nephrons of the mammalian kidneys have loops of Henle, which are the most efficient way to reabsorb water and produce concentrated urine to conserve water in the body. [12]
