Overview: The purpose of this lesson is to teach students about the basic structures and functions of the human body and how they relate to personal health.

Rational: The student will benefit from this activity because they will learn about the human body and how it relates to personal health.

Duration: 30 minutes

Instructional Objectives:

  • Students will learn the major organs in the body and their function.
  • Students will learn the major systems of the body.
  • Students will learn behaviors that will help protect the body structure.

Procedure: Use the following questions to guide discussion with your students.

What are the major organs in our body and what do they do?

side view of brain Brain--enables us to think, speak, and feel. The brain puts all of our senses together and allows us to respond. For example, if we touch a hot stove, our senses send a message to our brain, our brain says "ouch that is hot, remove hand" then sends a message to our hand to remove it. This reaction is very quick.

drawing of human heart Heart--pumps oxygenated blood throughout our body.

What are our major body systems and what do they do?

picture of the digestive systemThe Digestive System includes our mouth, esophagus (tube from mouth to stomach), stomach, and anus. Our stomach breaks down the food that we eat and absorbs vitamins and minerals from the food. The remaining part of the food exits our body through the anus.

picture of nervous system The Nervous System involves the brain and nerve cells. The nervous system controls activities in our body. It makes sure that our heart beats and that we breath. It allows us to think and move our body.

picture of circulatory system The Circulatory System includes our heart, and blood vessels. It pumps blood throughout our body.

picture of human skullThe Skeletal System includes all the bones that make up our body. The skeletal system gives our body structure. What do you think our body would look like without bones? Without bones we wouldn't be able to stand upright.

picture of repiratory system The Respiratory System includes the nose, which leads to the trachea (or wind pipe), and then to the lungs. The respiratory system is important because it provides oxygen to our body's cells. Without oxygen, we would not be able to survive.

How do we protect our body from injury?

  • Wear a helmet when riding your bike.
  • When roller skating/blading or when skate boarding, wear a helmet, shin guards, and wrist guards.
