Answer 2

The initial filtrate such as glucose, amino acids, salts and water are selectively reabsorbed in nephrone.

Nephrone is functional unit of kidney.

In each kidney, there are approximately 1 million nephrones are present.

Each nephrone has 2 components

- vascular component

- tubular component

Arrangement of nephrones within kidney gives rise to 2 distinct regions.

- outer cortex : renal cortex (granular in appearance)

- inner medulla : renal medulla, made up of striated triangles called renal pyramids.
