Six levels of organization of the human body
chemical, cellular, tissue, organ, body system, total organism
Integumentary System
Covers and protects body; regulates temperature
Skeletal System
Provides body framework and support; protects; attaches muscles to bones; provides calcium storage
Muscular System
Produces movement; maintains posture; provides heat
Nervous System
Coordinates body activities; receive and transmits stimuli
Endocrine System
Regulates metabolic activities and body chemistry
Cardiovascular System
Transports material from one part of the body to another; defends against disease
Lymphatic System
Returns tissue fluid to the blood; defends against disease
Digestive System
Ingests and digests food; absorbs nutrients into blood
Respiratory System
Exchanges gases between blood and external environment
Urinary System
Excretes metabolic wastes; regulates fluid balance and acid-base balance
Reproductive System
Forms new individuals to provide continuation of the human species
Homeostasis
The constant internal environment that must be maintained for the cells of the body
Stressor
Any condition or stimulus that disrupts the homeostatic balance in the body
Negative Feedback
A type of regulation that responds to a change in conditions by initiating responses that will counteract the change. Maintains a steady state.
Positive Feedback
A type of regulation that responds to a change in conditions by initiating responses that will amplify the change. Takes organism away from a steady state.
Anatomical Position
erect, feet forward, arms at side with palms facing forward, head facing forward
Superior
Above or higher on the body, nearer to the head
