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 how health behaviors affect body systems.
  • Students will learn the basic function of major body systems.

Resources: Posters of Human Anatomy.

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

What are the 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.

What health behaviors affect body systems?

 

  • Exercise is very good for our body systems. It exercises our heart, which strengthens it. Exercise is also very good for reducing stress. Stress can cause many digestive, heart, and nervous problems.
  • Eating good foods is very important to our body systems. In order for our body systems to work properly, they need nutrients. We need to follow the food pyramid to fulfill our body's nutrient requirements.
  • Getting the proper amount of sleep is very important to our body systems. This allows our brain, heart, and other systems the chance to rejuvenate.
  • Smoking is bad for our respiratory system. It can cause many life threatening diseases, including: lung cancer and emphysema.
  • Alcohol is also bad for the body. It can damage our liver which is needed to filter toxins out of our body.
  • Drugs can have devastating effects on all of our body systems. Drugs affect the nervous system and can damage the heart and lungs.
