1. Physiology=function Anatomy=structure structure aids function Pathology=disease=bad A&P

2. why study physiology ? because you have to the language of health care recognize disease goals of treatment this is the story of you

3. functions of living things obtain energy from environment –change to useful form(ATP) obtain and process building materials –digest, absorb, transport communication and control –coordinate functions between tissues make more living things –reproduction, genetics

4. Organ Systems Integumentary Skeletal Muscular Nervous Endocrine Cardiovascular Lymphatic ; Immune Respiratory Digestive Urinary Reproductive fig 1.3 p6-7

5. integrated functions movement nutrition fluid balance elimination regulation making more individuals

6. Homeostasis = similar condition optimum conditions –temperature –blood pressure –glucose levels normal range keep things optimum for survival

7. homeostasis variablebody function or amount –set point“normal” level receptornotices change –stimulusany change that excites a receptor integration centercompares change to set point effectorcauses response

8. homeostasis

13. negative feedback response is opposite to change brings variable back to normal body temp BP glucose

17. inhibition response shuts off response –low glucose shuts off insulin production end-product inhibition –insulin shuts off insulin production –products shut off chemical reactions antagonsistsopposite effectors

19. positive feedback response increases the change –labor contractions –blood clotting still has an end pointno stimulus –baby not presentno stretch –clot formedno rough edge

20. homeodynamics homeostasis is dynamic optimum function for current condition –25 o F. outside –no food for 4 days –lions –exercise dynamic dysequilibrium

21. physiologic reflexes Sensation  Integration  Response appropriate responses to changes

22. physiologic reflexes receptornotices change afferent pathwaysensory neurons integration centerbrain endocrine glands efferent pathwaymotor neurons blood effectormuscle, organ, gland

26. science vs nonscience sciencethings that can be tested nonsciencethings that can be believed

27. learning science of the earlearn what we are told science of the eyelearn what we can see (sense)

28. Scientific Method science = deductions from reproducible data we must trust our senses we must trust our methods we analyze what we observe, not what we expect

29. Scientific Method observation hypothesis experiment –data collection deductions

30. Scientific Method 2 groups : experimental group –independent variablewe control values –dependent variablechanges w/ independent –elimination of other variables control groupindependent variable doesn’t change used for comparison to experimental group

31. data analysis - graphing x-axisindependent variable y-axisdependent variable curve –positive correlation –negative correlation
