  1. Body organization and structure • The Big Idea: The human body is composed of major systems that have differing functions, but all of the systems work together to maintain homeostasis. • SPI’s 0707.1.2 Interpret a chart to explain the integrated relationships that exist among cells, tissues, organs, and organ systems. 0707.1.3 Explain the basic functions of a major organ system.

  2. Body Organization and Structure Preview Section 1 Body Organization Section 2 The Skeletal System Section 3The Muscular System Section 4The Integumentary System Concept Mapping

  3. Bellringer # 1 List the four main types of plants. Turn Ch 7 NB in. Clear desk except for a piece of Notebook paper and a pencil.

  4. Section1 Body Organization Bellringer # 2 List 11 organ systems. Open text to pg 206. Set up notes for 8.1. CRA Due tom.

  5. Section1 Body Organization Objectives • Describehow tissues, organs, and organ systems are related. • List 11 major organ systems. • Identify how organ systems work together to maintain homeostasis.

  6. Section1 Body Organization Cells, Tissues, and Organs The maintenance of a constant internal state in a changing environment: homeostasis.

  7. Section1 Body Organization Cells, Tissues, and Organs, continued • Cells Form Tissues A group of similar cells working together forms a tissue. Your body has four main kinds of tissue.

  8. Section1 Body Organization Cells, Tissues, and Organs, continued • Tissues Form OrgansTwo or more tissues working together to carry out a specialized function form an organ.

  9. Section1 Body Organization Working Together • Organs Form Systems Organs that work together make up an organ system. • Organ systems work together make up the organism. • Organ systems work together to maintain homeostasis. • Your body has 11 major organ systems.

  10. Section1 Body Organization

  11. 8.1 Vocab • Cell • Homeostasis • Tissue • Organ • Organ system • Organism

  12. Section1 Body Organization Bellringer #3 Match the body system in the first column with the correct function in the second column: 1. respiratory system a. regulates body functions 2. muscular system b. breaks down food 3. digestive system c. pumps blood 4. circulatory system d. absorbs oxygen 5. endocrine system e. moves bones Clear desk. CRA due

  13. Bellringer # 4 List three kinds of muscle tissue. Open text to pg 210. Set up Notes for 8.2.

  14. Section2 The Skeletal System Objectives • Identify the major organs of the skeletal system. • Describe four functions of bones. • Describe three types of joints. • List three injuries and two diseases that affect bones and joints.

  15. Section2 The Skeletal System Bones • Bones, cartilage, and connective tissue that holds bones together make up the skeletal system. • Adult skeleton has 206 bones

  16. Functions of Skeletal System:

  17. Bone Structure Bone tissue without any visible open spaces: compact bone. Bone tissue that has many open spaces: spongy bone. Bones contain a soft tissue called marrow. • Bone Growth Most bones start out as a flexible tissue called cartilage. Eventually, most cartilage is replaced by bone.

  18. Section2 The Skeletal System Joints • place where two or more bones meet: joint which are held together byligaments: connect bone to bone.

  19. 8.2 vocab • Skeletal system • Joint • Bones • Cartilage • Marrow • Ligaments

  20. Section3 The Muscular System Objectives • List three kinds of muscle tissue. • Describe how skeletal muscles move bones. • Compare aerobic exercise with resistance exercise. • Describe two muscular system injuries.

  21. Section3 The Muscular System Kinds of Muscle • The muscular systemis made up of the muscles that let you move. • Involuntary muscle found in the digestive tract and the walls of the blood vessels: smooth muscle. Involuntary muscle found in your heart: cardiac muscle. • Muscle attached to your skeleton for movement: skeletal muscle which can be voluntary or involuntary.

  22. Section3 The Muscular System Movement • Muscles Attach to BonesTendons: strands of tough connective tissue that connect your skeletal muscles to your bones. • Muscles Work in Pairs Skeletal muscles often work in pairs.

  24. 8.3 Vocab • Voluntary • Involuntary • Smooth muscle • Cardiac muscle • Skeletal muscle • Tendon

  25. Section4 The Integumentary System Bellringer # 5 Describe the functions of the skeletal system. Open text to pg 218. Set up notes for 8.4

  26. Section4 The Integumentary System Objectives • List four functions of skin. • Describe the two layers of skin. • Describe the structure and function of hair and nails. • Describe two kinds of damage that can affect skin.

  27. Section4 The Integumentary System Functions of Skin • Your skin, hair, and nails make up your integumentary system. • Skin protects you by keeping water in your body and foreign particles out of your body.

  28. Functions of Skin cont. • Nerve endings in your skin let you feel things around you. • Skin helps regulate your body temperature and get rid of waste chemicals.

  29. Section4 The Integumentary System Layers of Skin • Epidermis: outermost layer of skin in which most cells are dead. • Dermis: thicker layer of skin that lies beneath the epidermis.

  30. Section4 The Integumentary System

  31. Section4 The Integumentary System Hair and Nails • A hair forms at the bottom of a tiny sac called a hair follicle. • Hair protects skin from ultraviolet light and helps regulate body temperature. • A nail grows from living cells in the nail root at the base of the nail. Nails protect the tips of your fingers and toes.

  32. 8.4 Vocab • Integumentary system • Epidermis • Dermis • Hair follicle • Sweat gland • Nerve endings
