Kidneys
The kidneys are organs gland, which bears the important function of producing urine, on both sides of the spinal column. They are on the outside of the cavity perioneal, occupying the posterior region of the abdomen, at the height of the last two dorsal vertebrae and the first three lumbanres. The kidneys are never equal, in general being left something larger. The difference in level is typically 2 cm on the left being higher. Each kidney (including some which glandular formations are located in the upper pole, adrenal glands) is housed in a capsule called fibroadipose cell, with walls formed by a fibrous tissue. These walls leave an opening at the bottom surrounding the ureter to the bladder, so the kidney can sometimes descend (nefroptosis) in particular tissues of the capsule fibroadipose fibroadipose is lower than normal.
Kidney bean-shaped, with two sides, front and rear, a convex outer edge, an inner edge, concave in its center, and two rounded poles, top and bottom. In the hilar blood vessels entering and leaving the ureter and is immediately followed by a deep cavity, called within the kidney.
Contained within the kidney, surrounded by a fatty mass, the many divisions of renal vessels and ducts of the home appliance excretorio. The breast has a more or less rectangular, flat front and back is surrounded on all sides by the least hilar renal parenchyma by
