Chapter 1 Flashcards
Organ systems: Integumentary
Forms the external body covering
Protects deeper tissue from injury
Helps regulate body temperature
Location of cutaneous nerve receptors
Organ Systems: Skeletal
Protects and supports body organs
Provides muscle attachment for movement
Site of blood cell formation Stores minerals
Organ Systems: Muscular
Produces movement
Maintains posture
Produces heat
Organ Systems: Nervous
Fast-acting control system
Responds to internal and external change
Activates muscles and glands
Organ Systems: Endocrine
Secretes regulatory hormones for Growth, Reproduction, Metabolism
Organ Systems: Cardiovascular
Transports materials in body via blood which is pumped by heart. Oxygen Carbon dioxide Nutrients Wastes
Organ Systems: Lymphatic
Returns fluids to blood vessels Cleanses the blood Involved in immunity
Organ Systems: Respiratory
Keeps blood supplied with oxygen Removes carbon dioxide
Organ Systems: Digestive
Breaks down food Allows for nutrient absorption into blood Eliminates indigestible material as feces
Organ Systems: Urinary
Eliminates nitrogenous wastes Maintains acid-base balance Regulates water and electrolytes
Organ Systems: Reproductive
Produces offspring Testes produce sperm and male hormone Ovaries produce eggs and female hormones
Maintaining Homeostasis: Receptor
Responds to changes in the environment (stimuli) Sends information to control center
Maintaining Homeostasis: Control center
Determines set point Analyzes information Determines appropriate response
Maintaining Homeostasis: Effector
Provides a means for response to the stimulus
Maintaining Homeostasis: Negative feedback
Includes most homeostatic control mechanisms Shuts off the original stimulus, or reduces its intensity Works like a household thermostat
