Medicine:List of organs of the human body

Short description: none

This article contains a list of organs of the human body. A general consensus is widely believed to be 78 organs; however, there is no universally standard definition of what constitutes an organ, and some tissue groups' status as one is debated. Since there is no single standard definition of what an organ is, the number of organs varies depending on how one defines an organ. For example, this list contains much more than 78 different organs.
