1. HBS 1.1.1 Amazing Facts - 2 days
STEVE HARRIS
SPASH – BIOMEDICAL

2. PROCEDURE
Form a table team of four. Each team will be assigned one of 11 human body systems. Your assigned system is now referred to as your “primary system”.
1. Cardiovascular system, 2. Respiratory system, 3. Endocrine system, 4. Nervous system, 5. Digestive system, 6. Urinary system, 7. Reproductive system, 8. Skeletal system, 9. Muscular system, 10. Integumentary system, and 11. Lymphatic and Immune system.
Obtain a blank copy of the body system graphic organizer from your teacher. Set this handout aside temporarily.
Divide your team into two pairs. Each pair should use the Internet to find 10 unusual, interesting, and/or amazing facts about your primary system. Write them in your notebooks.
These facts must be things you would not expect your classmates to know. Choose facts that are fun and interesting!
As a pair, share your 10 facts with the entire team.
As a team, select the “Top 5” amazing facts for your primary system.
Share the five facts with your teacher and get approval before you go to the next step.
Label the body system graphic organizer with the name of your primary system.
Determine what specific organs from the primary system are involved in each of your five facts. Research the function of these organs and their locations in the body.

3. Procedure
Draw and label these organs on the human body diagram using colored pencils. Draw only the most important organs, and be sure you know how large the organs should be and where they should be located.
Obtain one piece of chart paper and one colored marker for your team. Each team should have a different color marker. In large print, neatly write the name of the primary system you were assigned as a heading on the chart paper. List your five facts, leaving space between each one. Use the same color marker for the heading and the facts.
When your group is called to the front of the classroom, use tape to post your chart paper on the board. You may also display one complete body system graphic organizer for your primary system on the overhead projector. Present and explain each of your amazing facts.
As each team presents their facts, decide if your primary system plays a role in any of the facts being discussed. A secondary system is a system that has cells, tissues, and/or organs that are impacted by or work with the primary system. Does your primary system act as a secondary system here?
Raise your hand and explain your connection to the presenting group. If the class decides that a relationship exists between these two systems, add the name of the secondary system under the appropriate fact on the chart paper. Your group can add the connection or a member of the other system group can come up and write on the chart paper. Write one sentence explaining the importance of this secondary system to the function or processes described in that fact. Include important secondary organs in this description or list them below the sentence.

4. Procedure Use the following example fact and scenario as a guide.
Scenario: Your primary system is the respiratory system. You look at the poster for the cardiovascular system and see the Fact below listed on the chart.
You know that the respiratory system plays a role in this fact, so you raise your hand and suggest that this system be added to the chart paper as shown below.
The skeletal system team also feels their system plays a role in the fact, and their information is added to the chart as well.
Fact: Red blood cells make about 250,000 trips around the human body before returning to the bone marrow (where they were created) to die.
Assigned (primary) system: Cardiovascular
Most important organs: heart, blood vessels (drawn on body system handout)
Secondary systems to include on the chart paper:
Respiratory: Red blood cells carry oxygen throughout the body. Organs – lungs, diaphragm muscle
Skeletal: Bone marrow, located in the center of bones, creates red blood cells. Organ - bones

5. Procedure
Continue to share ideas and make connections between systems as each group presents.
When all teams have presented, make sure you have at least five examples of how secondary systems are involved with primary systems.
Return to your body system graphic organizer. In the space next to the human body outline, neatly write the facts associated with your primary system and draw a line to the organs identified as important to each fact?. List associated secondary systems under each fact. Using information from the activity, draw in any secondary organs that play a role in the facts. Label each secondary organ with an asterisk (*).
Add an additional title at the top of the organizer that says, “Amazing Facts – A Relationship between Body Systems.”
Keep your graphic organizer in the front of your binder. You will complete organizers for many other body systems over the course of the year. For now, your team is the class expert in your primary system. You will get extra copies of the blank organizer from the teacher as needed. Be sure each one has the title of the system it represents. You may have more than one for each system by the end of the course.

6. CONCLUSION Questions
Without looking back in your notes, list as many of the eleven body systems as possible. If you missed any of the eleven, look back in your notes, add them to your list with an asterisk after them.
Cardiovascular system, Respiratory system, Endocrine system, Nervous system, Digestive system, Urinary system, Reproductive system, skeletal system, Muscular system, Integumentary system, and Lymphatic
Describe an example that demonstrates how one human body system impacts the effectiveness of another.
EXAMPLE: The respiratory system effects the circulatory system because red blood cells have to carry oxygen to other organs.

7. Conclusion Questions
Describe three body processes or functions that all humans have in common.
Respiration- breathing
Involuntary nervous activity- heartbeat
Digestive System-getting nutrition
Provide an example of an individual difference that may impact the functioning of one of the human body systems.
EXAMPLE: A genetic difference in the respiratory system. If a person has allergies or asthma it can affect breathing.

8. Conclusion Question
Diseases and/or medical conditions often involve more than one system. In fact, the effects on a secondary system may be as serious as the primary system most associated with the problem. For example, heart disease can often cause fluid buildup in the lungs. The primary system in this example is the cardiovascular system; the secondary system is the respiratory system. Fluid in the lungs will prevent the lungs from functioning properly causing the respiratory system to fail, yet the problem started with the cardiovascular system. Describe another medical condition or disease where the primary system causes a serious problem with a secondary system.
Example: If your cardiovascular system fails the lack of blood flow will affect the kidneys and affect renal filtering
