Question

Skin is also considered as an excretory organ. Give reason if you agree. [HOTS]

Answer 1

Skin is also considered as an excretory organ because it secretes sweat.

• Skin is an excretory organ because it removes water, salts and urea from the body of an organism.
• The excess water, salts and urea are removed by producing sweat through the skin.
• Toxic substances are removed through skin.
• Hence, as skin is also involved in removing of excretory products, it is an excretory organ.
