Answer 2

Internal structural features of Kidneys

Location – Between levels of the last thoracic and the 3rd lumbar vertebra

Measurement (L × B × Thickness) – 10 – 12 cm × 5 -7 cm × 2-3 cm

Weight – 120-170 g

Hilum – A notch present towards the centre of the inner concave surface of the kidney

Through the hilum, the ureter, blood vessels and the nerves enters the kidney.

On the inside of the hilum, the renal pelvis is present. Renal pelvis has projections called calyces.

2 zones in the kidney: Cortex (outer) and Medulla (inner)

Medulla divides into medullary pyramids. These medullary pyramids project into the calyces.

Cortex is present in between the medullary pyramids as renal columns called as the columns of Bertini.

Each kidney consists of 1 million nephrons.
