An organ system is made of a few organs that perform multiple functions.

Here's why:

* Organ systems are groups of organs that work together to perform a complex function. For example, the digestive system includes organs like the stomach, intestines, and liver, all working together to break down food and absorb nutrients.

* Organ systems are not made of a single type of tissue. Each organ within a system is made of multiple tissues, and those tissues work together to carry out the specific function of the organ.

* Organ systems are not simply multiple organs working independently. The organs in a system are interconnected and rely on each other to function effectively.
