Answer 2

Answer:

Carbon dioxide

Explanation:

• Excretion is the process by which products of metabolism are removed from the body. Several wastes and injurious substances are formed during metabolism which includes CO₂, excess water and salts, a number of nitrogenous waste products like ammonia, uric acid, and bile pigment. Removal of these waste products is essential for normal body function.

• The excretory organs include lungs, skin, liver, alimentary canal, and kidneys.

• Skin by forming sweat serves to eliminate water, urea, and salts that are actively secreted from blood capillaries of the skin, from which water also evaporates.

• Lungs help to eliminate CO₂ that is transported by the blood from tissues in exchange for Oxygen of the alveoli.

Hence Skin: Sweat:: Lungs: Carbon dioxide (CO₂).
