World kidney day is a global campaign which is celebrated on 2nd thursday in March, where March is also known as kidney month.

Let's gain some knowledge of Kidney on World Kidney Day..

• Gross Anatomy:

Shaped like limia beans; lie against posterior abdominal wall, behind peritoneum at level of last thoracic and first three lumbar vertebrae; right kidney slightly lower than left.

• External Structures: Hilum, renal capsule
• Internal structures: cortex, medulla, pyramids, columns, papillae, calyces, pelvis .
• Blood Flow in the kidney: Kidney receives 20% of cardiac output during rest; reduced to 2% to 4% during physical or emotional stress. Abdominal aorta gives rise renal arteries, which enter the hilum of each kidney; eventually branch into afferent arterioles, which enter glomerular capillary beds. Efferent arterioles leave the glomerular capillary bed.
• Nephron: Anatomic and functional unit of a kidney; approximately 1 million per kidney. Functions via principles of filteration, reabsorption, and secretion.
• Collecting tubules: Final osmotoic reabsorption of most of the remaining water in urine occurs; under antidiuretic hormone influence.
• Urine description/composition

1. Amount: 1.5L/day average (30ml/hr)
2. Color: light yellow to darker
3. Odor: aromatic; food and drugs alter odor and color
4. Specific gravity: 1.005 to 1.030 is average
5. Urine pH: Usually acidic (4.5 to 7.5 is average)
