Question

Which statement about the skin as an excretory organ is directly supported by the slides?
Options
A The skin excretes urea through bile production
B Capillaries close to the skin surface help eliminate or conserve heat, and sweat glands excrete urea and salts
Correct Answer
C The skin excretes carbon dioxide as its primary metabolic waste
D Sebaceous glands excrete nitrogenous waste
Correct Answer

Option B is the correct answer.

Detailed Explanation

The slides support that capillaries close to the skin surface help eliminate or conserve heat (thermoregulation), and sweat glands excrete urea and salts. This dual function makes the skin important for both excretion and temperature regulation.

Hint

This organ's excretory function is combined with thermoregulation through sweat production.
