<h3>What does a biological system mean?</h3>

A biological system is a collection of organs that cooperate to carry out a certain task. For instance, the circulatory system transports nutrients and waste products to and from the body's cells, while the skeletal system protects and supports the body.

Cells, organelles, macromolecular complexes, and regulatory pathways are examples of biological systems that exist on the micro to nanoscopic scale. A living system, such as an organism, should not be confused with a biological system.

The aim of systems biology is to understand vastly complex biological systems in a way that enables us to model and predict how they will behave.
