  1. The Human Body Life Sustaining Processes

  2. Let’s Take A Look … Inside the Human Body • Start at 2:50min.

  3. Overview … • Respiratory System • Circulatory System • Nervous System • Skeletal System • Muscular System • Integumentary System • Exocrine System • Endocrine System • Digestive System • Lymphatic System • Urinary System Life Sustaining Processes: • Support & Movement • Energy Flow • Regulation • Defense • Waste Management • Gas Exchange • Responds

  4. This weeks topics Homeostasis Comparative Anatomy Levels of Organization

  5. Comparative Anatomy • Your body is just like a machine.. Only BETTER..!! • Think about your body: How is the human body similar to non-living objects… ??

  6. Homeostasis • Staying healthy keeps our body in balance!! • Regulation of life sustaining conditions is called Homeostasis

  7. Internal Life Sustaining conditions: • Temperature

  8. Internal Life Sustaining conditions: • Blood Pressure • pH • Blood Sugar

  9. Levels of Organization • Cells • Basic unit of life • Tissues • Made of different cells working together • Organs • Made of different tissues working together • Organ Systems • Made of different organs working together Organisms

  10. BIG IDEA: Working together to achieve homeostasis …. Topic 2: • Support & Movement • Skeletal System • Muscular System • Nervous System

  11. Skeletal System Function: • Gives the body: • Support • Form • Protection

  12. Skeletal System Structure: • Bones • Ligaments • Cartilage

  13. Skeletal System Structure: • Bones • 206 bones • Store Minerals • Make Blood Cells • Protect Organs • Attachment for muscles

  14. Skeletal System Structure: 2. Ligaments • Hold bones together

  15. Skeletal System Structure: 3. Cartilage • Protects the ends of bones • Forms Ears & Nose

  16. So.. What are the 3 structures of the Skeletal System? • Bones • Ligaments • Cartilage

  17. We have 206 bones… We will learn 22 bones …

  18. Muscular System Function: • Attaches to bones (movement) • Allows movement inside the body (blood, food, urine) • Generate body heat

  19. Muscular System Structure: • Skeletal Muscles • 600 muscles attach to bones & move bones at joints • Smooth Muscle • Make tubed organs like intestines, blood vessels & bladder • Cardiac Muscle • Make the heart

  20. There are over 600 skeletal muscles … • We will learn 14 skeletal muscles …

  21. Nervous System Function: • Sends impulse to muscles & glands Structures: • Brain • Spinal cord • Nerve cells • Sense organs (Eyes, Nose, Tongue, Skin)

  22. How to the 3 Systems Work together? • Skeletal System • Muscular System • Nervous System • Nerves send an impulse to the Muscles • Muscles contract & pull on Bones • Bones then cause movement at joints • Nerves also send impulses to cardiac & all smooth muscles. • Those muscles contract and cause internal movement for urine, blood & food.
