  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. The renal tubule extends from the capsule.

  3. 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). The proximal tubule can be further ...

  4. Collecting duct system - Wikipedia

    en.wikipedia.org/wiki/Collecting_duct_system

    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.

  5. Loop of Henle - Wikipedia

    en.wikipedia.org/wiki/Loop_of_Henle

    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 ...

  6. Renal physiology - Wikipedia

    en.wikipedia.org/wiki/Renal_physiology

    Each nephron begins in a renal corpuscle, which is composed of a glomerulus enclosed in a Bowman's capsule. Cells, proteins, and other large molecules are filtered out of the glomerulus by a process of ultrafiltration , leaving an ultrafiltrate that resembles plasma (except that the ultrafiltrate has negligible plasma proteins ) to enter Bowman ...

  7. Kidney - Wikipedia

    en.wikipedia.org/wiki/Kidney

    The nephron is the structural and functional unit of the kidney. Each adult human kidney contains around 1 million nephrons, while a mouse kidney contains only about 12,500 nephrons. The kidneys also carry out functions independent of the nephrons.

  8. Reabsorption - Wikipedia

    en.wikipedia.org/wiki/Reabsorption

    Reabsorption. In renal physiology, reabsorption or tubular reabsorption is the process by which the nephron removes water and solutes from the tubular fluid (pre-urine) and returns them to the circulating blood. [1] It is called reabsorption (and not absorption) because these substances have already been absorbed once (particularly in the ...

  9. Ascending limb of loop of Henle - Wikipedia

    en.wikipedia.org/wiki/Ascending_limb_of_loop_of...

    Structure. The ascending limb of the loop of Henle is a direct continuation from the descending limb of loop of Henle, and one of the structures in the nephron of the kidney. The ascending limb has a thin and a thick segment. The ascending limb drains urine into the distal convoluted tubule. The thick ascending limb is found in the medulla of ...
