    • 1. Ch. 13; Homeostasis, Bones, Muscles, Levers Organ Systems & Homeostasis The Skeletal System The Muscular System Machines and the Body Types of Levers
    • 2. Ch. 13; Homeostasis, Bones, Muscles, Levers Organ Systems & Homeostasis The Skeletal System The Muscular System Machines and the Body Types of Levers
    • 3. Main IdeasPlants & animals have levels of organization; cells,tissues, organs, organ systems.Bones & muscles work together for movement.Joints in the bones can be found in machines.Hinge, ball-and-socket, sliding.Levers convey mechanical advantage.
    • 4. Organ Systems & HomeostatisHomeostasis; The ability of an organism to keepa stable internal environment regardless of theweather, etc. ie sweating & shivering.
    • 5. Cells
    • 6. Tissues
    • 7. Eleven Organ Systems Crime NerdsiCirculatory system; Blood & carrying oxygen.Respiratory system; Breathing & burning food.Integumentary system; Skin & protection.Muscular system; Muscles & movement.Endocrine system; Hormones & communication.Nervous system; Nerves, sensing & responding.Excretory; Kidneys & taking out the trash.Reproductive system; Eggs & sperm & making copies.Digestive system; Intestines & food processingSkeletal system; Bones & supportImmune system; White cells antibodies & protection.
    • 8. Digestive & Excretory
    • 9. Integumentary system
    • 10. Nervous system
    • 11. Circulatory system
    • 12. Immune system
    • 13. Skeletal systemMovementProtectionCalcium & phosphorous storageBlood cell production
    • 14. Bone connections; jointsImmovable joints; sutures ie skullMovable joints;Ligaments; hold bones togetherCartilage; keeps bones in a joint from rubbing.Tendon; attaches muscle to bone.Compact, spongy, marrow; a living system.
    • 15. Hinge, ball-&-socket
    • 16. Sliding & Pivot Joints
    • 17. Bone Internal Structure
    • 18. Muscular SystemInvoluntary; digestive tract, pupils“auto pilot”.Voluntary; bone muscles; “think &move”.Skeletal; voluntary, moves body.Cardiac; Involuntary, heart.Smooth; Involuntary, digestive,blood vessels.
    • 19. Muscle pairsMuscles only work when they contract.So, they have to work in pairs.Start... stop. Return... stop.
    • 20. Machines & the BodyForce; A push or pull.Work; A force exerted over distance. W = F X DForce is measured in Newtons.Work = lift 50N X 3m = 150N-m of work is done.What if the object weighs more than you can lift?A machine allows you to do more work using Levers.Math practice; pg. 535.
    • 21. Levers, work, & force...
    • 22. Calculating Mechanical Advantage
    • 23. Three Classes ofInsert diagram from pg. 537 of text
    • 24. Bone-Muscle Levers and Fulcrums
