  2. Interstitial nephritis - Wikipedia

    en.wikipedia.org/wiki/Interstitial_nephritis

    There are a variety of known factors that can provoke the inflammatory process within the renal interstitium, including pharmacologic, environmental, infectious and systemic disease contributors. The spectrum of disease presentation can range from an acute process to a chronic condition with progressive tubular cell damage and renal dysfunction.

  3. Descending limb of loop of Henle - Wikipedia

    en.wikipedia.org/wiki/Descending_limb_of_loop_of...

    The presence of aquaporin-1 channels in the thin segment facilitates high water permeability, crucial for water reabsorption as part of the kidney's countercurrent exchange mechanism. [ 4 ] [ 5 ] They can be distinguished from the vasa recta by the absence of blood, and they can be distinguished from the thick ascending limb by the thickness of ...

  4. Loop of Henle - Wikipedia

    en.wikipedia.org/wiki/Loop_of_Henle

    The interstitium of the kidney increases in osmolarity outside as the loop of Henle descends from 600 mOsm/L in the outer medulla of the kidney to 1200 mOsm/L in the inner medulla. The descending portion of the loop of Henle is extremely permeable to water and is less permeable to ions, therefore water is easily reabsorbed here and solutes are ...

  5. Interstitium - Wikipedia

    en.wikipedia.org/wiki/Interstitium

    The renal interstitium facilitates solute and water transport between blood and urine in the vascular and tubular elements of the kidneys, and water reabsorption through changes in solute concentrations and hydrostatic gradients. [9] [10] The myocardial interstitium participates in ionic exchanges associated with the spread of electrical events ...

  6. Ascending limb of loop of Henle - Wikipedia

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

    Within the nephron of the kidney, the ascending limb of the loop of Henle is a segment of the heterogenous loop of Henle downstream of the descending limb, after the sharp bend of the loop. This part of the renal tubule is divided into a thin and thick ascending limb ; the thick portion is also known as the distal straight tubule , in contrast ...

  7. 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.

  8. Collecting duct system - Wikipedia

    en.wikipedia.org/wiki/Collecting_duct_system

    The collecting duct system of the kidney consists of a series of tubules and ducts that physically connect nephrons to a minor calyx or directly to the renal pelvis.The collecting duct participates in electrolyte and fluid balance through reabsorption and excretion, processes regulated by the hormones aldosterone and vasopressin (antidiuretic hormone).

  9. Juxtaglomerular apparatus - Wikipedia

    en.wikipedia.org/wiki/Juxtaglomerular_apparatus

    The juxtaglomerular apparatus is part of the kidney nephron, next to the glomerulus. It is found between afferent arteriole and the thick ascending limb of the loop of Henle (distal straight tubule) of the same nephron. This location is critical to its function in regulating renal blood flow and glomerular filtration rate. [2] [3]
