Structure of kidney: The kidneys are paired retroperitoneal organs located

The kidneys are paired retroperitoneal organs located between the T12 and L3 vertebrae, positioned lateral to the spine and adjacent to multiple abdominal structures. Each kidney comprises the renal parenchyma—divided into cortex and medulla containing nephrons, the functional units—and the collecting system, which conveys urine to the ureter (see Image. Kidney Anatomy). The kidneys perform essential roles in excreting nitrogenous wastes, regulating electrolytes and acid-base balance ...
