Answer 1

Answer:

The kidneys are two bean-shaped organs in the renal system. They help the body pass waste as urine. They also help filter blood before sending it back to the heart. Creating hormones that help produce red blood cells, promote bone health, and regulate blood pressure.

Answer 2

Kidneys:-

Location: Between levels of the last thoracic and the third lumbar vertebra

Measurement: 10−12 cm (length) × 5−7 cm (width) × 2−3 cm (thickness)

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 nerves enter 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)

Medulla (inner)

Medulla divides into medullary pyramids (cone-shaped). These medullary pyramids project into the calyces.

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

Each kidney consists of about 1 million nephrons. These are the structural and functional units of the kidneys.
