,Excretion is the removal of metabolic wastes from
the living organism.
Metabolic wastes are waste substances that are
produced during metabolic reactions.
Some examples of the metabolic wastes are urea, uric
acid and carbon dioxide.
These substances can be very dangerous if allowed to
accumulate in the body.
For example if carbon dioxide is allowed to collect in the
body it combines with water to form carbonic acid.
This would change the pH of the tissue fluid and affect
the functioning of enzymes.
