Animal anatomy resources are appropriate for middle school, high school and college level study. Because of the difficulty of anatomical vocabulary, we recommend using the simpler animal diagrams for elementary students found in the animal database (more than 500 available). Let us know if there is an animal you would like to see added to the collection.

LS1.A Structure and Function
K-2 All organisms have external parts that they use to perform daily functions.
3-5 Organisms have both internal and external macroscopic structures that allow for growth, survival, behavior, and reproduction.
6-8 All living things are made up of cells. In organisms, cells work together to form tissues and organs that are specialized for particular body functions.
9-12 Systems of specialized cells within organisms help perform essential functions of life. Any one system in an organism is made up of numerous parts. Feedback mechanisms maintain an organism’s internal conditions within certain limits and mediate behaviors.
