A group of organs is known as a SYSTEM. This term is used to refer to a collection of organs that work together to perform a specific function in the body. For example, the digestive SYSTEM is made up of organs such as the stomach, small intestine, and large intestine, which all work together to break down food and absorb nutrients. Similarly, the respiratory SYSTEM consists of organs such as the lungs, trachea, and bronchi, which all work together to bring oxygen into the body and expel carbon dioxide.
