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.

Section 1 Body Organization Objectives Describe how tissues, organs, and organ systems are related. List 11 major organ systems. Identify how organ systems work together to maintain homeostasis.

Cells, Tissues, and Organs Section 1 Body Organization Cells, Tissues, and Organs The maintenance of a constant internal state in a changing environment: homeostasis.

Cells, Tissues, and Organs, continued Section 1 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.

Section 1 Body Organization Cells, Tissues, and Organs, continued Tissues Form Organs Two or more tissues working together to carry out a specialized function form an organ.

Organs Form Systems Organs that work together make up an organ system. Section 1 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.

Objectives Identify the major organs of the skeletal system. Section 2 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.

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

Functions of Skeletal System:

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.

Section 2 The Skeletal System Joints place where two or more bones meet: joint which are held together by ligaments: connect bone to bone.

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.

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.

Muscles Work in Pairs Skeletal muscles often work in pairs. Section 3 The Muscular System Movement Muscles Attach to Bones Tendons: strands of tough connective tissue that connect your skeletal muscles to your bones. Muscles Work in Pairs Skeletal muscles often work in pairs.

Objectives List four functions of skin. Section 4 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.

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.

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.

Dermis: thicker layer of skin that lies beneath the epidermis. Section 4 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.

Section 4 The Integumentary System

A hair forms at the bottom of a tiny sac called a hair follicle. Section 4 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.
