An organ is a collection of tissues working together to perform a particular function. A body system consists of a group of organs that work together to perform a specific function. An organism is a life form made up of interdependent parts (cells, tissues, organs, and body systems), all of which work together to maintain life. Copyright Goodheart-Willcox Co., Inc.
