Human Body



The human body is the most wonderful, complex machine in the world! Your body can walk, run, climb, and sit. It can see, hear, smell, taste, and feel. It can eat, talk, laugh, lift things, play games, think, and read.

While these things are going on, you're body is also breathing' circulating blood, and digesting food.  In fact, this marvelous machine is at work even when you are sleeping .

Background information:

A few systems of the human body include:

The nervous system:  the brain , spinal cord, and millions of nerve cells in the body make up the nervous system   

The circulatory system: The circulatory system is made up of your heart, arteries, veins, and very thin blood vessels called capillaries.

The digestive system: the mouth, esophagus, stomach, large and small intestines and other organs make up the  digestive system .

The excretory system: ammonia is carried by the blood to the liver,  it is changed to urea, urea is carried by the blood to the kidneys, ureters move urine into the bladder, when the bladder is full urine leaves the body through the urethra

The respiratory system: Oxygen enters your body through the nose or mouth, moves down the windpipe and into the lungs. The lungs are the most important part of your respiratory system .

  The Task    


The Plattekill Museum has selected you to be a member of a team of doctors that will create an exhibit of the nervous system, the circulatory system, the digestive system, the excretory system, and the respiratory system. Your task is to inform the public of the role of the organs within each system and the importance of each system to the function of a healthy human body .


Nervous System:

  • What are the sense organs? What function do they serve?
  • What is the difference between sensory nerves and motor nerves?
  • What is the function of the brain, nerves, and spinal cord?
  • What is the difference between the central nervous system and the peripheral nervous system?
  • Draw and label the organs of the nervous systems.

Circulatory System:

  • What is the function of the heart, the lungs, and blood vessels in the circulatory system?
  • Draw a diagram of a heart and label all parts showing how blood circulates through the chambers, lungs, and body.
  • Describe the differences between red blood cells, white blood cells, plasma, and platelets.

Links that will help you:









Digestive System:

  • What are the functions of the following organs in the digestive process: the mouth, esophagus, stomach, small intestine, large intestine, and rectum?
  • Describe the process that occurs within the digestive system when you eat and apple.
  • Draw a diagram showing the organs of the digestive system.

  Links that wwill help you:






Respiratory System:

  • What is the primary function of the respiratory system?
  • What is the function of the trachea, lungs, and diaphragm in respiration?
  • How does the exchange of oxygen and carbon dioxide occur in the lungs and tissues?
  • Draw and label the organs of the respiratory system.


 Excretory System

  • Draw and label the organs of the excretory system.
  • What is the main function of the excretory system?
  • Which organ filters waste from the blood?
  • When dos the skin take part in excretion?


  The Process     

  1. You need to research each system.
  2. Answer all the above questions in your science journal
  3. Record important facts and make diagrams or drawings of the systems
  4. Put together your final presentation. Presentations may include the following: oral report with posters, displays, art, games, multimedia presentations, songs, stories, multimedia projects, etc.
  5. Finally, present your project to the Science Club members.

1.You will receive a quiz grade for the work completed in your science journal.

2. You will also be graded according to your final product.

  • Is your work neat?
  • Are your posters well done and readable?
  • Have you been creative in your presentation?
  • Do you have accurate information?


You have explored and learned about some systems and the organs of your body. You have shown what you have learned by making models, charts, posters, creative books, etc. 

You might want to investigate the muscular system, the skeletal system , urinary system , endocrine system, or the reproductive system. Here are some interesting links:

How is our body similar to plant life? You may decide to look up some information on plant life to compare with what you have learned about your body . Here are some links that may interest you regarding plants:
