Human Organs

• The human body is made up of many organs that
  work together to accomplish all of the tasks
  required in a healthy functioning organism. To
  understand the function of organs, you need to
  know where they are found in the human body.

Procedure

• On a large piece of paper (obtained from you
  teacher), trace an outline of your torso.
• Brainstorm with your partner(s) about the
  location, relative size, and shape of the
  following organs of the human body lungs, heart,
  liver, stomach, intestines, and kidneys.
• Using separate pieces of paper, sketch the organs
  to actual size, cut them out, and place them on
  the appropriate locations on the outline on the
  large piece of paper.

• E.g. the respiratory system, which works to
  exchange oxygen and carbon dioxide gases
