Question

Number of uriniferous tubules in a kidney of Frog is

• A. Numerous
• B. 10,000
• C. 5,000
• D. 2,000

Answer 1

The correct option is D 2,000

Kidney of frog is made up of a large number of minute (microscopic) tubes about 2,000 in number are known as uriniferous tubules or nephrons bound together by connective tissue. Each uriniferous tubule is the structural and functional unit of the kidney.

Thin-walled expanded cup-shaped blind end of each tubule is called ‘Bowman’s capsule. The Bowman’s capsule leads into a long coiled ciliated urinary tubule.

So the correct answer is '2,000'.
