TermDefinition
Anatomy The Study of the structures of the body.
Physiology The study of how the body functions.
Organization of the body Ranges from simple to complex.
Epithelial Tissue Covers or lines body surfaces.
Connective tissue Connects and supports parts of the body; some transports and stores minerals
Muscle Tissue Contracts to produce movement.
Nerve Tissue Generates and transmits impulses to regulate body functions.
Integumentary system (Skin, Hair, Nails) Key Functions: Protection, Temperature regulation, Water retention, Sensations.
Skeletal System (Bones, Cartilage, Ligaments) Key Functions: Protection of body organs, Support, Movement, Blood formation.
Muscular System (Primarily skeletal muscles) Key Functions: Movement, Posture, Heat productions.
Lymphatic Systems (Lymph nodes,lymphatic vessels,lymph, thymus, spleen, and tonsils) Key Functions: Role in fluid balance, Production of immune cells, Defense against disease.
Respiratory System ( Nose, pharynx,larynx, trachea,bronci, and lungs) Key Functions: Absorption of oxygen, discharge of carbon dioxide, acid-base balance, speech)
Urinary System ( Kidneys, ureters,urinary bladder, and Urethra) Key Functions: Excretion of waste, regulation of blood volume and pressure, control of fluid, electrolyte, and acid-base balance.
Nervous System ( Brain, spinal cord, and sense organs) Key Functions: Control, regulation and coordination of other systems, Sensation, Memory.
Endocrine System ( Pituitary gland, adrenals, pancreas, thyroid, parathyroids, and other organs) Key Functions: Hormone Production, Control and regulation of other systems.
Circulatory System Key Functions: Distribution of oxygen, nutrients, wastes, hormones, immune cells,electrolytes,and antibodies, fluid, electrolyte, and acid- base balance
Digestive System Key Function: Breakdown and absorption of nutrients; elimination of waste
Female Reproductive System Key Functions: Production of eggs, birth, fetal site, lactation, secretion of sex hormones

Proximal Closest to the point of orgin
Distal Farthest from the point of orgin
Medial Towards the body midline
Superficial At or near the body's surface
Deep Away from the Body's surface
Negative Feedback When the effector opposes the stimulus and reverses the direction of change.
Kinetic Energy Energy in motion
Metabolism All of the chemical reactions in the body
Anabolism Building larger and more complex chemicals from smaller subunits
Factors that affect reaction rate Temperature, concentration, catalyst
Mixture 2 or more substances blend together rather than chemically combine
Compound 2 or more elements combine to create a new subsance
Soultion Consist of particles of matter dissolved in a more abundant substance, usually water.
Colloid Can change from liquid to gel
Suspension Contain large particles, making the suspension cloudy or opaque
The more hydrogen produced....... The stronger the acid
PH Scale The acidity or alkalinity of the substance. Scale ranges from 0-14.
Ph of Blood 7.35-7.45
Four major organic compound groups: Carbohydrates, lipid,proteins, nucleic acid
Organic Vast array pf compounds that contain carbon
Carbohydrates The body's main source of energy
Essential amino acids Eight amino acids must be obtained from food
Nucleic Acids DNA and RNA
In ATP when energy is released... Bonds are broken through chemical reactions
