Describe the structure of a human kidney with the help of a labelled diagram.
The human kidney is a reddish-brown bean-shaped structure situated between the last thoracic and third lumbar vertebra close to the dorsal inner wall of the abdominal cavity.
Each kidney of an adult human measures 10-12 cm in length 5-7 cm in width, 2-3 cm in thickness with an average weight of 120-170 gm.
The kidney is covered by fibrous connective tissue, the renal capsule, which protects the kidney Internally, It consists of the outer dark cortex and an inner light medulla, both containing nephron (structural and functional units of the kidney.
The renal cortex is granular in appearance and contains the loop of Henle, collecting ducts and tubules and ducts of Bellini.
The medulla is divided into conical masses, the medullary pyramids which further form papillae. The papillae from calyces, join to renal pelvis leading to the ureter. Between the medullary pyramids, the cortex extends into the medulla and forms renal columns which are called the column of Bertini.
