  2. Ultrafiltration (kidney) - Wikipedia

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

    In renal physiology, ultrafiltration occurs at the barrier between the blood and the filtrate in the glomerular capsule (Bowman's capsule) in the kidneys. As in nonbiological examples of ultrafiltration , pressure (in this case blood pressure ) and concentration gradients lead to a separation through a semipermeable membrane (provided by the ...

    The kidney is responsible for about half of the total gluconeogenesis in fasting humans. The regulation of glucose production in the kidney is achieved by action of insulin, catecholamines and other hormones. [14] Renal gluconeogenesis takes place in the renal cortex.

  4. Nephron - Wikipedia

    en.wikipedia.org/wiki/Nephron

    The nephron is the functional unit of the kidney. [3] This means that each separate nephron is where the main work of the kidney is performed. A nephron is made of two parts: a renal corpuscle, which is the initial filtering component, and; a renal tubule that processes and carries away the filtered fluid. [4]: 1024

    en.wikipedia.org/wiki/Kidney

    Filtration, which takes place at the renal corpuscle, is the process by which cells and large proteins are retained while materials of smaller molecular weights are [30] filtered from the blood to make an ultrafiltrate that eventually becomes urine.

  6. Mammalian kidney - Wikipedia

    en.wikipedia.org/wiki/Mammalian_kidney

    The kidneys in mammals are usually bean-shaped [4] or externally lobulated. [5] They are located behind the peritoneum (retroperitoneally) [6] on the back wall of the body. [7] The typical mammalian kidney consists of a renal capsule, a peripheral cortex, an internal medulla, one or more renal calyces, and a renal pelvis. [7]

  7. Tubular fluid - Wikipedia

    en.wikipedia.org/wiki/Tubular_fluid

    Tubular fluid is the fluid in the tubules of the kidney. It starts as a renal ultrafiltrate in the glomerulus , changes composition through the nephron , and ends up as urine leaving through the ureters .

    Micrograph of proteinaceous material in Bowman's space, which is unspecific. It is present in about 5% of people aged over 60 years, [2] but also in for example hypertensive kidney disease. Measuring the glomerular filtration rate (GFR) is a diagnostic test of kidney function. [3] A decreased GFR may be a sign of kidney failure. [citation needed]
