A&P CHAPTER 1: INTRO Flashcards
ANATOMY
STUDY OF STRUCTURE OF BODY PARTS AND HOW THEY ARE ORGANIZED
PHYSIOLOGY
STUDY OF HOW BODY PARTS WORK
PATHOPHYSIOLOGY
STUDY OF CHANGES ASSOCIATED WITH DISEASE/INJURY
SUBDIVISIONS OF AANATOMY
GROSS (MACROSCOPIC)
MICROSCOPIC
DEVELOPMENTAL
ORGANIZATION LEVELS OF THE BODY IN ORDER
ATOM -> MOLECULE -> MACROMOLECULE -> ORGANELLE
-> CELL -> TISSUE -> ORGAN -> ORGAN SYSTEM -> ORGANSIM
CYTOLOGY
SUBDIVISION OF MICROSCOPIC ANATOMY THAT FOCUSES ON BODY CELLS
HISTOLOGY
SUBDIVISION OF MICROSCOPIC ANATOMY THAT FOCUSES ON BODY TISSUES
TISSUE LEVEL
TISSUES WORK TOGETHER AND PERFORM ONE OR MORE SPECIFIC FUNCTIONS
ORGAN LEVEL
TISSUES OF AN ORGAN WORK TOGETHER PERFORMING SEVERAL FUNCTIONS
ORGAN SYSTEM LEVEL
GROUPS OF ORGANS INTERACT AND PERFORM PARTICULAR FUNCTIONS
CHARACTERISTICS OF HUMAN LIFE (9)
MOVEMENT
RESPONSIVENESS
DIGESTION
EXCRETION
GROWTH
RESPIRATION
ABSORPTION
CIRCULATION
ASSIMILATION
ELEMENTS OF SURVIVAL FOR HUMANS (5)
NUTRIENTS
WATER
OXYGEN
ATMOSPHERIC PRESSURE
BODY TEMPERATURE
HOMEOSTASIS
STABLE INTERNAL BODY ENVIRONMENT NEEDED FOR HUMAN BODY TO SURVIVE
2 MAIN SYSTEMS FOR MAINTAINING HOMEOSTASIS
NERVOUS AND ENDOCRINE
HOW NERVOUS AND ENDOCRINE SYSTEMS MAINTAIN HOMEOSTASIS
NERVOUS: FAST SHORT TERM ELECTRICAL IMPULSES
ENDOCRINE: SLOW BUT LONGER TERM
AUTOREGULATION
AKA INTRINSIC
BODY STRUCTURE OR SYSTEM ADJUSTS ITS ACTIVITIES BECAUSE OF CHANGE IN ENVIRONMENT
EXTRINSIC REGULATION
NERVOUS OR ENDOCRINE SYSTEM ACTIVITY WHERE THESE SYSTEMS INFLUENCE OTHER BODY SYSTEMS ACTIVITIES SIMULTANEOUSLY
THREE COMPONENTS OF HOMEOSTATIC CONTROL AND HOW THEY WORK
RECEPTORS
CONTROL CENTER
EFFECTORS
RECEPTORS “SENSORS” MONTOR THE ENVIRONMENT AND SEND INFO TO THE CONTROL CENTER
THE CONTROL CENTER HAS A DETERMINED SET POINT AND ANALYZES THE INPUT FROM THE RECEPTORS TO DETERMINE RESPONSES
EFFECTORS THEN CARRY OUT THE CONTROL CENTER’S DECISION OF RESPONSE
NEGATIVE FEEDBACK
PREVENTS THE CORRECTION OF DEVIATIONS FROM DOING TOO MUCH
MAIN CONTROLLER OF HOMEOSTASIS
POSITIVE FEEDBACK
MAKES CONDITIONS MOVE AWAY FROM THE NORMAL STATE TO STIMULATE FURTHER CHANGES
PRODUCE EXTREME RESPONSES
EXAMPLES OF POSITIVE FEEDBACK
CONTRACTIONS FOR CHILD BIRTH, BLOOD CLOTTING
MOST DISEASES OCCUR BECAUSE OF _____
HOMEOSTATIC IMBALANCE
