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
Interpret a chart to explain the integrated relationships that exist among cells, tissues, organs, and organ systems.

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. Adult skeleton has 206 bones
Section 2 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.

20. Objectives List three kinds of muscle tissue.
Section 3 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. The muscular system is made up of the muscles that let you move.
Section 3 The Muscular System
Kinds of Muscle
The muscular system is 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. Muscles Work in Pairs Skeletal muscles often work in pairs.

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. Section 4 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. Nerve endings in your skin let you feel things around you.
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.

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.
