From simplest to complex, an organism is made up of cells, tissues, organs, and organ systems. Cells make up the most basic level of organization; the cell is the building block of a living organism. This is followed by tissues. Tissu...

In the biology dictionary, an organ is a group of tissues that collectively form a functional unit that is specialized to carry out a certain function. The Latin organum phrase means an “instrument” or “tool”. The most common examples when people think about organs are the kidneys, brain, lungs, and heart.
The main tissues that make up an organ tend to have common embryologic origins, such as arising from the same germ layer. Organs exist in most multicellular organisms. In single-celled organisms such as members of the eukaryotes, the functional analogue of an organ is known as an organelle.
