We know about the parts inside our body. The inside organs of our body are known as internal organs.

Some internal organs function in groups. They constitute various systems that perform many crucial functions in the body. Most prominent among those are respiration, blood - circulation, food-digestion etc. Thus, a group some of our bodily organs, performing a specific function in the body is known as a system.
