Title: Serge Francois | Human Anatomy and Physiology


1
Human Anatomy and Physiology
  • Introduction

Serge Francois
2
Topics
  • Autonomic nervous system
  • Endocrinology
  • Cardiovascular physiology
  • Immunology
  • Respiratory physiology
  • Renal physiology
  • Digestion
  • Reproductive physiology

Homeostasis
4
Homeostasis
  • All organs interact
  • All cells of organs bathed in internal fluid
  • Cells exist if fluid remains constant in quantity
    and quality (osmosis)
  • Fluctuations occur within narrow limits

Feedback mechanisms
Disturbance
Negative feedback
-
Control system
Sensor
Error signal
Inverted amplifier
Set point adjustment
6
Negative feedback
  • Beneficiale.g. perspiration
  • Disturbance (increase in body temp.)
  • Sensor (nervous system)
  • Inverted amplifier (decrease in temp.)
  • Doesnt prevent displacement
  • Restores stability close to operating parameters
    (set point adjustment)

Feedback mechanisms
Disturbance
Positive feedback

Signal
Control system
Sensor
Amplifier
Output
8
Positive Feedback
  • Rare
  • Mostly destructivee.g. congestive heart failure
  • Disturbance (inability of heart to pump blood)
  • Sensor (nervous system)
  • Amplifier (increase in heart muscle contraction,
    further impeding pumping ability)
