Body organization and structure

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.

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.

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.

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

27. 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.

28. 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.

29. 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.

30. 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.

31. Section4 The Integumentary System

32. 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.
