detailed presentation on basics of physiology

1. INTRODUCTION
TO PHYSIOLOGY

2. WHAT IS PHYSIOLOGY
PHYSIOLOGY is the science of studying the functional activities and its
mechanisms in human body
PHYSIOLOGY derived from two Greek works
PHYSIS = Nature
LOGOS = study

3. TOPICS
 GENERAL PHYSIOLOGY
RESPIRATORY SYSTEM
DIGESTIVE SYSTEM
CARDIOVASCULAR SYSTEM
BLOOD
ENDOCRINE SYSTEM
SENORY ORGANS
SKELETOMUSCULAR SYSTEM
RENAL SYSTEM
REPRODUCTIVE SYSTEM
NERVOUS SYSTEM

4. FUNDAMENTAL
OF PHYSIOLOGY

5. HOMEOSTASIS
Homeostasis is the self-regulating process by which
organisms maintain stability while adjusting to changing
conditions.
Homeostasis is a condition in which the internal environment
of the body remains relatively constant despite changes in
external environment
Examples mainatence of body temperature, levels of blood
glucose
milieu intérieur - internal environment
Claude Bernard used the French phrase milieu intérieur (internal
environment in English)

6. HOMEOSTATIC MECHANISMS
HEMOSTASIS is achieved through
NEGATIVE feedback mechanism
POSITIVE feedback mechanism

7. NEGATIVE FEEDBACK

10. EXAMPLES OF POSITIVE FEEDBACK
CLOTTING
LACTATION
ACTION POTENIAL
PARTURITION
