Human Body Organ Systems Worksheet

This NGSS human body organ systems worksheet corresponds nicely to our Human Body Test (middle school level) but it works equally as well as a straightforward middle school level practice worksheet or homework. All information is appropriate for an NGSS-based middle school unit, not high school anatomy.

Topics Include:

  • Organization within living things (cell, tissue, organ, organ system)
  • Basic structures and functions of organ systems (digestive, respiratory, circulatory, nervous, skeletal, muscular, endocrine, reproductive, immune, integumentary, excretory)
  • Path air takes in the body and that gases exchange in the lungs
  • Systems that are necessary for cellular energy (respiratory for oxygen, digestive for food)
  • General understanding of mechanical vs. chemical digestion
  • Understanding that systems work together to maintain homeostasis

Teacher Notes:

  • INCLUDES ANSWER KEY.
  • Please note that this organ systems worksheet is not editable.
  • Includes a Google Slides version for distance learning or a paperless review.
