  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. The tuft is structurally supported by the mesangium (the space between the blood vessels), composed of intraglomerular mesangial cells.

  3. Glomerulus - Wikipedia

    en.wikipedia.org/wiki/Glomerulus

    Glomerulus (/ ɡ l ə ˈ m ɛr (j) əl ə s, ɡ l oʊ-/; pl.: glomeruli) is a common term used in anatomy to describe globular structures of entwined vessels, fibers, or neurons. Glomerulus is the diminutive of the Latin glomus, meaning "ball of yarn". Glomerulus may refer to: Glomerulus (kidney), the filtering unit of the kidney

  4. Glomerulus (olfaction) - Wikipedia

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

    In mammals, glomeruli typically range between 50-120 μm in diameter and number between 1100 and 2400 depending on the species, with roughly between 1100 and 1200 in humans. [1] [2] The number of glomeruli in a human decreases with age; in humans that are over 80 they are nearly absent. [5]

  5. 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 ...

  6. Glomerular filtration rate - Wikipedia

    en.wikipedia.org/wiki/Glomerular_filtration_rate

    Glomerular filtration rate (GFR) is the volume of fluid filtered from the renal (kidney) glomerular capillaries into the Bowman's capsule per unit time. [4] Central to the physiologic maintenance of GFR is the differential basal tone of the afferent (input) and efferent (output) arterioles (see diagram).

  7. Mesangial cell - Wikipedia

    en.wikipedia.org/wiki/Mesangial_cell

    Mesangial cells (colored in purple) as seen within intraglomerular and extraglomerular mesangium. Mesangial cells have irregular shapes with flattened-cylinder-like cell bodies and processes at both ends containing actin, myosin and actinin, giving mesangial cells contractile properties. [5]

  8. Glomerulonephritis - Wikipedia

    en.wikipedia.org/wiki/Glomerulonephritis

    Glomerulonephritis (GN) is a term used to refer to several kidney diseases (usually affecting both kidneys). Many of the diseases are characterised by inflammation either of the glomeruli or of the small blood vessels in the kidneys, hence the name, [1] but not all diseases necessarily have an inflammatory component.

  9. Glomerulosclerosis - Wikipedia

    en.wikipedia.org/wiki/Glomerulosclerosis

    Glomerulosclerosis is the hardening of the glomeruli in the kidney. It is a general term to describe scarring of the kidneys' tiny blood vessels, the glomeruli, the functional units in the kidney that filter urea from the blood. Proteinuria (large amounts of protein in the urine) is one of the signs of glomerulosclerosis. Scarring disturbs the ...
