In a multicellular organism, an organ is a collection of tissues joined in a structural unit to serve a common function. [1] . In the hierarchy of life, an organ lies between tissue and an organ system. Tissues are formed from same type cells to act together in a function.
The human body has 78 different organs. The largest organ is the skin, while the smallest organ is the pineal gland, which produces the hormone melatonin.

Organ, in biology, a group of tissues in a living organism that have been adapted to perform a specific function. In higher animals, organs are grouped into organ systems; e.g., the esophagus, stomach, and liver are organs of the digestive system. Learn more about organs in this article.
There are ten major such systems in the human body; integumentary, musculoskeletal, nervous, endocrine, lymphatic, cardiovascular, respiratory, digestive, urinary and reproductive. A variety of organs are found in the body; they will be explored systematically through their anatomy and function (s).
