Our Body Systems

1. Our Body Systems Mrs. Puckli Day 1

2. Bell Ringer! • Welcome to Quarter Three Health with Mrs. Puckli!!! • Take the Bell Ringer at the side table RESPIRATORY DIAGRAM and get started immediately upon entering!

3. Respiratory System • Organs that supply your blood with oxygen • Mouth • Nose • Cilia –tiny hair like particles that line your nose and trap dirt and particles • Trachea • Lungs • Diaphragm

4. Parts of the Respiratory System • Trachea- passageway in your throat that takes air into and out of your lungs • Epiglottis- flap of tissue in the back of your mouth that keeps food out of your trachea (activity) • Bronchi-two passageways that branch from the trachea, one to each lung

5. Parts of the Respiratory System • Lungs- two large organs that exchange oxygen and carbon dioxide • Diaphragm- large, dome shaped muscle below the lungs. Expands and compresses the lungs-enabling breathing.

6. Breathing Process

7. Taking Care of your Respiratory System • Avoid Tobacco use • Stay away from people who smoke • Take care of your body when you have the flu or respiratory illnesses • Drink plenty of fluids • Eat a healthful diet • Be physically active on a regular basis

9. Nervous System • Body's control center • Carries messages back and forth between your brain and all parts of your body • SMELL, TOUCH, HEAR, TASTE, SEE

10. Parts of the Nervous System 1. Central nervous system • Brain • Spinal Cord 2. Peripheral Nervous System • Nerves that connect the central nervous system to all parts of the body

11. Central Nervous System • Brain- MOST important part • Command center, coordinator, of the nervous system • Spinal Cord • Long bundle of neurons that sends messages to and from the brain and all parts of the body

12. Activity with partner

13. Taking Care of your Nervous System • Eat nutritious foods • Get enough rest • Vaccinate against harmful diseases • Protect yourself from physical injury • Helmet, protective eyewear • Lifting properly • Follow traffic laws, wear seat -belt

14. Journal Entry • What do you think happens to food once you take a bite of something? Name the sequence of organs in the digestive system?

15. Objective • Identify Digestive, Circulatory, Muscular, and Skeletal systems in the body and their primary function • List major components of these body systems • Explain actions necessary to keep the body systems healthy

16. Digestive System • Group of organs that work together to break down foods into substances that your cells can use

17. Where does it begin? • Mouthtear and grind food with your teethSaliva • Saliva-digestive juice produced by salivary glands in your mouth-moistens and softens food making it easier to swallow • Amylase- enzyme in saliva that breaks down carbohydrates in food changing it from starch to sugar • Enzyme-substance that aids in body's chemical reactions

18. Digestive Organs • Swallowesophogus • Esophogus-contracts and relaxes and repeatedly moves the food along to the stomach • Stomachchurn and mix the foodsmall intestine • Small intestine- coiled tube from 20-23 ft long in which about 90 % of digestion takes place • Food combines with enzymes and Villi, on the wall of the small intestine, take in nutrients from food

19. Digestive Organs • Small Intestinecolon (Large Intestine) • Colon- tube 5-6 ft in length that plays a part in both digestion and excretion • Last stop for solid food

20. Caring for your Digestive System • Eat balanced diet with low-fat, high fiber food • Fiber helps system work properly • Drink enough water-60-70% of your body weight is made up of water • Keep teeth healthy • Get regular physical activity-systems work better

21. Circulatory System(cardiovascular system) • A group of organs and tissues that act as a transfer station carrying needed material to cells and removing their waste products • Heart- center of circulatory system • Blood vessels • Blood • Cardio (heart)-vascular (blood vessels) system

22. Circulation Path • Pg 72

23. Caring for Circulatory System • Make aerobic activity a habit-improves cardiovascular endurance • Steps up the supply of oxygen and nutrients to your body • Moderate-vigorous activity-helps cut the amount of fatty material in your blood • Balanced food plan • Manage stress-stress can strain your heart and blood vessels • Avoid tobacco-nicotine narrows blood vessels-cutting down on oxygen supply

24. Skeletal and Muscular Systems • Skeletal- framework of bones and other tissues that supports the body • Protects internal organs • Helps us move • 206 bones in the body

25. Definitions • Joints- places where two or more bones meet 1. Allow bones to move 2. Protect organs • Tendons- type of connecting tissue that joins muscle to bones and muscle to muscle • Achilles- attaches your calf to your heel bone • Ligaments- type of connecting tissue that holds bones to other bones at the joint (knees and ankles) • Cartilage- strong, flexible tissue that allows joints to move easily, cushions bones, and supports soft tissue • Tip of your nose • Knee joint

26. Muscular System • Tissue that moves parts of the body and control the organs • Power and flexibility you need to move • Skeletal • Smooth • Cardiac

27. Skeletal Muscles • Voluntary-you can control them • Turning your head-brain sends the message to muscles in your neck • Moving your arm

28. Smooth Muscles • Body’s organs • Body’s blood vessels • Involuntary- move without you consciously controlling their movement • stomach

29. Cardiac Muscle • HEART • involuntary

30. Caring for your Bones and Muscles • Stay physically active • Flexibility exercises • Stand up straight-proper posture keeps bones, joints, and muscles in the right place • Lifting heavy objects-keep your back straight, bend your knees • Eat healthy-muscles and bones get the right nutrients and food provides fuel for energy • What nutrient can help build muscle?
