  2. Kidney - Wikipedia

    en.wikipedia.org/wiki/Kidney

    The kidney also receives input from the parasympathetic nervous system, [23] by way of the renal branches of the vagus nerve; the function of this is yet unclear. [ 22 ] [ 24 ] Sensory input from the kidney travels to the T10–11 levels of the spinal cord and is sensed in the corresponding dermatome . [ 22 ]

  3. Urinary system - Wikipedia

    en.wikipedia.org/wiki/Urinary_system

    The human urinary system, also known as the urinary tract or renal system, consists of the kidneys, ureters, bladder, and the urethra. The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites , and regulate blood pH .

  4. Renal physiology - Wikipedia

    en.wikipedia.org/wiki/Renal_physiology

    Renal physiology (Latin renes, "kidneys") is the study of the physiology of the kidney. This encompasses all functions of the kidney, including maintenance of acid-base balance; regulation of fluid balance; regulation of sodium, potassium, and other electrolytes; clearance of toxins; absorption of glucose, amino acids, and other small molecules ...

  5. Mammalian kidney - Wikipedia

    en.wikipedia.org/wiki/Mammalian_kidney

    The function of the kidneys is regulated by the autonomic nervous system and hormones. [36] The potential for regeneration in mature kidneys is limited [37] [38] because new nephrons cannot be formed. [39] But in cases of limited injury, renal function can be restored through compensatory mechanisms. [40]

  6. 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 .

  7. Kidney (vertebrates) - Wikipedia

    en.wikipedia.org/wiki/Kidney_(vertebrates)

    Blood enters the kidney through the renal artery, which in the multilobar kidney then branches in the region of the renal pelvis into large interlobar arteries that pass through the renal columns. [ 62 ] [ 63 ] The pyramids consist mainly of tubules that transport urine from the cortex, that produces it by blood filtration, to the tips of the ...

  8. Glomerular filtration rate - Wikipedia

    en.wikipedia.org/wiki/Glomerular_filtration_rate

    The kidney has many functions, which a well-functioning kidney realizes by filtering blood in a process known as glomerular filtration. A major measure of kidney function is the glomerular filtration rate (GFR). The glomerular filtration rate is the flow rate of filtered fluid through the kidney.

  9. Renal lobe - Wikipedia

    en.wikipedia.org/wiki/Renal_lobe

    The renal lobe is a portion of a kidney consisting of a renal pyramid and the renal cortex above it. [1] In humans, on average there are 7 to 18 renal lobes. [medical citation needed] It is visible without a microscope, though it is easier to see in humans than in other animals.
