In biology, an organ (Latin: organum, "instrument, tool") is a group of tissues that perform a specific function or group of functions. Common animal organs include the heart, lungs, brain, eye, stomach, spleen, pancreas, kidneys, liver, intestines, skin, uterus, bladder, bone, etc. A group of related organs is an organ system.

Organelles are analogous sub-cellular structures.
