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
