  4. Mammalian kidney - Wikipedia

    en.wikipedia.org/wiki/Mammalian_kidney

    Mammalian kidneys are susceptible to ischemic injury because mammals lack a renal-portal system, and as a result, vascular vasoconstriction in the glomeruli can lead to decreased blood supply to the entire kidney. The kidneys are susceptible to toxic injury, since toxins are reabsorbed in the tubules along with most of the filtered substances. [47]

    The renal crest usually appears in animals larger than rabbits. [68] The kidneys of bovines are multilobar with external lobation. [72] Marine mammals, bears and otters have reniculate kidneys which are made of large amount of lobes called reniculi. [73] Each renculus can be compared to a simple unipapillary kidney as a whole.

  6. Collecting duct system - Wikipedia

    en.wikipedia.org/wiki/Collecting_duct_system

    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. At times of extreme dehydration, over 24% of the filtered water may be reabsorbed in the collecting ...

    The kidneys filter about 150 quarts (170 liters) of blood daily, but most of it is returned to the blood stream with only 1-2 quarts (1-2 liters) ending up as urine. [53] The urine is brought by the ureters from the kidneys down to the bladder .

  8. Renal pelvis - Wikipedia

    en.wikipedia.org/wiki/Renal_pelvis

    Like the bony pelvis, the renal pelvis (/ ˈ r iː n əl ˈ p ɛ l v ɪ s /) gets its English name via Neo-Latin from the older Latin word pelvis, "basin", as in "wash basin". [4] In both cases the name reflects the shape of the structure, and in the case of the renal pelvis, it also reflects the function.

  9. Renal circulation - Wikipedia

    en.wikipedia.org/wiki/Renal_circulation

    The renal circulation supplies the blood to the kidneys via the renal arteries, left and right, which branch directly from the abdominal aorta. Despite their relatively small size, the kidneys receive approximately 20% of the cardiac output .
