What is the function of all the human organs To make a full human body?
Most organs in the human body serve a particular purpose, and
many organs have more than one purpose. Some organs, like wisdom
teeth and erector pili are essentially useless and are called
vestigial. Other organs like the gall bladder or tonsils are
useful, but not essential. Your question is a vague but just about
every organ in the human body is essential for life.
