1. What are metabolic wastes?
2. Which are the main organs of the excretory system?

1. Metabolic wastes or excrements are substances left over from metabolic processes which cannot be used by the organism, and must therefore be excreted.

2. Organs of excretion include the skin, liver, large intestine, lungs, and kidneys.
