1. HUMAN ORGAN SYSTEMS Revised by Jessie Moreau, 2015 Based upon the original 2008 PowerPoint by Mr. William Johnson Molly Strong, Zedna Malcolm Gwinnett County School System S7L2 - Students will describe the structure and function of cells, tissues, organs, and organ systems. e. Explain the purpose of the major organ systems in the human body (i.e., digestion, respiration, reproduction, circulation, excretion, movement, control, and coordination, and for protection from disease). Characteristic of Science: Organizes data into graphs, tables and charts.

2. Throughout this PowerPoint there will be songs via audio file links: These are hyperlinked to a CD called, The Human Body by Ron Brown. Due to copyright issues, you will need to have a copy of the CD inserted into your hard drive. Gwinnett County Teachers: You may borrow this CD from the Adapted Curriculum Lab. Science Standards: S7L2 - Students will describe the structure and function of cells, tissues, organs, and organ systems. e. Explain the purpose of the major organ systems in the human body (i.e., digestion, respiration, reproduction, circulation, excretion, movement (muscular), control, and coordination, and for protection from disease). ELA Standard: ELAGSE.7.W.2 - Write informative/explanatory texts to examine a topic and convey ideas, concepts, and information through the selection, organization, and analysis of relevant content. a. Introduce a topic clearly, previewing what is to follow; organize ideas, concepts, and information, using strategies such as definition, classification, comparison/contrast, and cause/effect; include formatting (e.g., headings), graphics (e.g., charts, tables), and multimedia when useful to aiding comprehension.

3. Digestive System Main Organs Mouth, Esophagus, Stomach Function Break down food to make energy for the body (eating). Mouth Stomach Esophagus

4. Digestive System Fun Facts: Your stomach, is a stretchy sack shaped like the letter J. You get a new stomach lining every 3-4 days J

5. Respiratory System Main Organs Nose and lungs Function Take in (inhale) oxygen and let out (exhale) carbon dioxide to breathe Nose Lungs

6. Respiratory System Fun Fact: You take more than 20,000 breaths when just sitting during a 24 hour day. Young children laugh an average of 300 times a day; adults average only 15-100 times a day.

7. Circulatory System Main Organs Heart and Blood Vessels Function Heart pumps blood through the body Blood vessels move oxygen and nutrients throughout the body Heart Blood Vessels

8. Circulatory System Fun Facts: It takes only 20 seconds for blood to circulate (travel) through the entire body! The heart makes enough energy each day to drive a truck 20 miles!

9. Skeletal System Bones Main Organ Bones throughout whole body Function Gives the body its shape

10. Skeletal System Fun Facts: At birth, babies have 300-350 bones, some of which fuse (join) together. An adult human has 206 bones. http://www.sciencephoto.com/media/290649/view

11. Muscular System Main Organs Muscles throughout whole body Function Help the body move muscles

12. Muscular System Skeletal Muscles You make them move (Legs, neck, hands, etc.) Involuntary Muscles They move by themselves (muscles to breathe; muscles to move blood, etc.) Cardiac Muscle Only found in the heart (helps heart beat) Cardiac Muscle Hand muscles Lung muscles

13. Muscular System Fun Facts: The most flexible muscle is the tongue, which can take many shapes and is always moving, even in sleep Human body has more than 600 muscles
