This article contains a list of organs of the human body. It is widely believed that there are 79 organs (this number goes up if you count each bone and muscle as an organ on their own, which is becoming more common practice to do[1][2]); however, there is no universal standard definition of what constitutes an organ, and some tissue groups' status as one is debated.[3] 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 more than 79 organs (about ~103).[vague]

The list below is not comprehensive, as it is still not clear which definition of an organ is used for all the organs in the list.

Organ related tables

Explanation of the levels in the human body; defines the column labels in the next table.
Level Definition
Organ systems A biological system consisting of a group of organs that work together to perform one or more functions.
Organ sub-systems A biological system consisting of a group of organs that work together to perform just one function.
Body parts Somewhat arbitrarily defined sections on the body based on what humans have historically thought was one thing with a primary function.
Organs A collection of tissues that structurally form a functional unit specialized to perform a particular function (some of the organs in this list perform multiple functions).
Organ parts The different sections that we tend to split a given organ into for medical purposes.
Tissue Consists of a group of structurally and functionally similar cells as well as their intercellular material.
Cells Organells enclosed in a membrane.
