Anatomy Physiology

Remember cells with similar functions combined to make tissues

4 types of tissue: • 1. Epithelial tissue • 2. Connective tissue • 3. Muscular tissue • 4. Nervous tissue

Epithelial tissue covers the body surface, lines the body cavities and forms glands

Connective tissue binds and supports the body (including bones, adipose, blood, lymph)

Muscular tissue moves the body and its parts (skeletal, smooth, and cardiac)

Nervous Tissue receives stimuli and transports signals (Central and peripheral)

Two or more tissues working together to perform a particular function make an organ

Groups of organs that cooperate to carry out a process make an organ system

The human body has 11 organ systems

2 protect the body from disease: Integumentary and Lymphatic (Including immune)

Integumentary System-- Barrier from disease

Integumentary System • Skin, Hair, Nails, Sweat and Oil Glands

Lymphatic System (immune system) Fights disease once foreign objects enter the body

Lymphatic System • Structures: White blood cells, Thymus, Spleen, Lymph nodes

2 for structure, support, movement: Skeletal and Muscular

Skeletal System • Supports body, Provides protection

Skeletal System Cont • Structures: Bones, Teeth, Cartilage, Ligaments, Tendons

Muscular System • Provides structure, Responsible for voluntary movement, circulates blood, moves food through digestive system

Muscular System Cont. • Structures: Skeletal muscle, Smooth muscle, cardiac muscle

4 for acquiring materials and energy: Skeletal, Muscular, Digestive and Respiratory

Digestive System-Converts food to usable materials

Digestive System Continued • Structures: Mouth, Pharynx, Esophagus, Stomach, Intestines

Respiratory System responsible for gas exchange (take in Oxygen put out Carbon dioxide)

Respiratory System Continued • Structures: Lungs, Pharynx, Larynx, Trachea

3 Excrete Waste: Integumentary, Respiratory, Excretory

Excretory System eliminates waste from body through the production of urine

Excretory System Cont. • Structures: Kidneys, Ureters, Bladder, Urethra

1 transport materials through the body: Circulatory

Circulatory System • Distributes materials throughout the body

Circulatory System Cont. • Structures: Heart, Blood vessels, Blood

2 Respond and Coordinate body Activities: Nervous and Endocrine

Nervous System coordinates the body’s response to environment through electrical impulse and short range chemical signals

Nervous System Continued • Structures: Brain, Spinal Cord, Nerves

Endocrine System coordinates the body’s response to environment through long range chemical signals called hormones

Endocrine System Continued • Structures: All glands (Hypothalamus, Pituitary, Thyroid, Pancreas, Ovaries, Testes)

2 Systems produce offspring: Endocrine and Reproductive

Reproductive System produces sex cells, fertilizes, nurtures and protects embryo and developing fetus

Reproductive System Cont. • Structures: – Male: Testes, Epididymis, Vas Deferens, Urethra, Penis – Female: Ovaries, Fallopian tubes, uterus, Vagina

All body systems work together to maintain homeostasis

Homeostasis is the maintenance and control of a stable internal environment

Examples: Body Temperature, Blood sugar levels, Oxygen levels, many more functions
