Anatomy
of the kidney
1) macroscopic
The kidneys are located on the back upper abdomen, behind the peritoneum, in front of the last two ribs and three large muscles (transversus abdominis, quadratus lumborum and psoas major). Kidney in adults penjangnya to 13 cm, 6 cm wide and weighing both kidneys is less than 1% by weight of the body or kidney weight between 120-150 grams.
Shaped like a pea, the numbers there are 2 pieces of the left and right, the left kidney is larger than the right kidney and the kidney in general men are longer than in female kidneys. Kidney retained in position by a thick fat pad. Longitudinal section of kidney shows two distinct regions of the cortex and medulla.
Medulla is divided into triangular wedges called the pyramid. Pyramids are surrounded by the cortex and is composed of segments of the nephron tubules and collecting ducts. Papillae or the apex of each pyramid form papillary ducts of Bellini which formed an integral part of many of the terminal collecting duct (Price, 1995: 773).
