Kidneys- Water to Water

“Water to Water, Dust to Dust – If you have to Pee, then you Must” is one of the captions that has been used to describe this image. 95% of urine is water and the” dust” is represented by organic and inorganic compounds.  These include urea, chloride, sodium, potassium, organic solutes including urea, creatinine, uric acid.  In addition there are trace amounts of enzymes, carbohydrates, hormones, fatty acids, pigments, and mucins.  The inorganic ions include sodium (Na+), potassium (K+), chloride (Cl–), magnesium (Mg2+), calcium (Ca2+), ammonium (NH4+), sulfates (SO42-), and phosphates (e.g., PO43-).

Description

“Kidneys – Water to Water” combines the histology of the kidney with its macroscopic image.  The nephron with the arteriole, glomerulus, Bowman’s capsule, proximal and distal convoluted tubules, loop of Henle, and collecting ducts are shown in the their distribution in the cortex and medulla of the kidney.  The collecting ducts enter the papilla, then the calyx and reach the ureters via the infundibulum and renal pelvis.
