In biology

The human body and animal bodies are very organized. Specialized

groups of cells form tissues, tissues form organs, and organs form

body systems.

An organ is a specialized group of tissues that performs a

particular function, and often more than one function. Examples of

organs are the brain, heart, eyes, bones, intestines, pancreas,

rectum, lymph nodes, ears, stomach, liver, and gallbladder. We have

close to seventy-eight organs in our body.

Organs may work together to form a body system. This is the case

with the major organs of the digestive system (mouth, esophagus,

stomach, small & large intestines, rectum, anus) along with its

accessory organs (salivary glands, liver, pancreas,

gallbladder).

In music

In music, an organ is a very large piano-based instrument. They

date back to Ctesibius of Alexandria, who lived between 285 BC and

222 BC. Today they are commonly found in catholic churches.
