Interrelated Body Systems


GRADE - 11

GOAL - The students will learn seven interrelated body systems and will be able to name one function of each.


  • Define what body system is
  • Name seven groups of organs
  • List one function for each group

LEARNING TASKS - As always - begin your lesson with DO NOW question on the board. "What makes your body move in your physical education class?" Give your students three to four minutes to write their thoughts down and give more time if needed. Have them share their ideas.

Accept your students' answers. Then - get to the point that all your groups of organs are interrelated. One group of organs depends on another. And if one group fails - it will cause problems for other group too.

Body systems are groups of organs that work together to support functions of the body. If functions are working properly - you are healthy and alive.

Present to your students seven systems.
