About This Quiz

The human body is everything that makes you human. It is composed of many systems that work together to perform a variety of functions and to keep the body at homeostasis. Apart from the parts we can see, which are the head, neck, legs and outer structures, there are also organs on the inside, mainly the brain, which runs everything from the release of hormones, to controlling voluntary actions, to turning on the flight-or-fight response.

The basic unit of which the human body is made is called the cell, and when cells are grouped, they become tissue, then organs including the heart, the kidneys, the liver, the stomach etc., and finally organ systems including the digestive system, the cardiovascular system, the reproductive system, and the respiratory system. 

How well do you know the human body, the same body you've been in from the time you were born? Are you a person who only knows its basic functions like the external organs, or are you an expert who should seriously consider going to medical school? If you would like to find out where on the scale of a novice to genius you would fall, then this is the quiz you need to take.
