An example of a system: The nervous system. This basic diagram shows that this system is made up of 4 different basic organs: the brain, the cerebellum, the spinal cord, and the nerves.

In biology, a system is a group of organs that together perform a certain task. Common systems, such as those present in mammals and other animals, seen in human anatomy, are those such as the circulatory system, the respiratory system, the nervous system, etc.

A group of systems composes an organism.

Human systems

Humans have a a variety of systems due to the complexity of the species' organism. These specefic systems are widely studies in Human anatomy. "Human" systems are also present in many animals.
