LEVEL 3!ORGANS■ Tissues that work together to perform a specific
activity
■ Most organs work within a single organ system -Stomach is part of the digestive system
■ Some organs work within more than one system
eg. Pancreas is part of the digestive and endocrine system

LEVEL 4!SYSTEMS■ Groups of two or more organs that work together
to perform a specific function for the organism
