  2. Glomerulus (kidney) - Wikipedia

    en.wikipedia.org/wiki/Glomerulus_(kidney)

    The glomerulus (pl.: glomeruli) is a network of small blood vessels (capillaries) known as a tuft, located at the beginning of a nephron in the kidney. Each of the two kidneys contains about one million nephrons.

  3. 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.

  4. Renal corpuscle - Wikipedia

    en.wikipedia.org/wiki/Renal_corpuscle

    A renal corpuscle (or Malpighian body [1]) is the blood-filtering component of the nephron of the kidney. It consists of a glomerulus - a tuft of capillaries composed of endothelial cells - and a glomerular capsule known as Bowman's capsule. [2]

  5. 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. The juxtaglomerular apparatus consists of three types of cells:

  6. Glomerular basement membrane - Wikipedia

    en.wikipedia.org/wiki/Glomerular_basement_membrane

    The glomerular basement membrane of the kidney is the basal lamina layer of the glomerulus.The glomerular endothelial cells, the glomerular basement membrane, and the filtration slits between the podocytes perform the filtration function of the glomerulus, separating the blood in the capillaries from the filtrate that forms in Bowman's capsule. [1]

  7. Bowman's capsule - Wikipedia

    en.wikipedia.org/wiki/Bowman's_capsule

    Bowman's capsule (or the Bowman capsule, capsula glomeruli, or glomerular capsule) is a cup-like sac at the beginning of the tubular component of a nephron in the mammalian kidney that performs the first step in the filtration of blood to form urine. A glomerulus is enclosed in the sac. Fluids from blood in the glomerulus are collected in the ...

  8. 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).

  9. Kidney - Wikipedia

    en.wikipedia.org/wiki/Kidney

    Filtration occurs in the glomerulus: one-fifth of the blood volume that enters the kidneys is filtered. Examples of substances reabsorbed are solute-free water, sodium, bicarbonate, glucose, and amino acids. Examples of substances secreted are hydrogen, ammonium, potassium and uric acid. The nephron is the structural and functional unit of the ...
