Answer 2

The Assertion is incorrect but the Reason is correct.

Assertion: The purpose of urine formation is to filter out undigested food from the intestine.

• This statement is incorrect.
• The purpose of urine formation is to filter out the nitrogenous wastes from the body.
• The nitrogenous waste is removed from humans in the form of urea. Urine is filtered multiple times by the kidney to concentrate it.
• Undigested food from the intestine is expelled from the body in the form of feces by the rectum.
• Thus, the Assertion is incorrect.

Reason: Kidneys filter the waste and produce urine.

• This statement is correct.

• Urine formation follows 3 main steps:

1. Glomerular Filtration: When blood is allowed to move through the fine pores of the glomerulus, it gets filtered.
2. Reabsorption: In the nephron's tubules, water, glucose, ions like Na⁺, Cl⁻, are reabsorbed into the blood.
3. Secretion: The filtrate is concentrated more by active absorption of wastes such as urea from the blood.

• Thus, the kidney's function is to filter the blood and produce urine.
• So, the Reason is correct.

Therefore, the Assertion is incorrect but the Reason is correct.
