                    INTRODUCTION TO THE HUMAN BODY

ANATOMY – The study of the structure of the body and the relationships between
its parts

PHYSIOLOGY – The study of function


                              PLAN OF THE BODY

1. The Anatomical Position – standard reference position for description of the
   body




2. Planes of Reference –

      Sagittal
      Frontal (Coronal)
      Transverse (Horizontal)

3. Body Cavities – The human body has two main cavities:

      Dorsal (posterior): subdivisions


      Ventral (anterior): subdivisions



Each cavity is lined with a double-layered serous membrane. Between the two
layers is a thin sheet of watery (serous) lubricating fluid.

      Parietal Layer –
      Visceral Layer –

4. Membranes and Fluids

      Dorsal:       membranes –
                    fluid –

      Ventral:      thorax                    abdominopelvic
                    Membranes -               membranes -
                    fluid –                   fluid –
                                                      INTRODUCTION TO THE HUMAN BODY

LEVELS OF ORGANISATION


1. Chemical Level –        atoms and molecules




2. Cellular Level – smallest living things in the body; chemicals combine to form
   cells and their subunits (organelles)

3. Tissue Level –
       4 Types:




4. Organ Level –


5. Systems Level –


6. Organismic Level – whole organism

BODY SYSTEMS

1. INTEGUMENTARY SYSTEM

2. SKELETAL SYSTEM

3. MUSCULAR SYSTEM

4. NERVOUS SYSTEM

5. ENDOCRINE SYSTEM

6. CARDIO-VASCULAR SYSTEM

7. LYPHATIC SYSTEM

8. RESPIRATORY SYSTEM

9. DIGESTIVE SYSTEM

10. URINARY SYSTEM

11. REPRODUCTIVE SYSTEM
                                                     INTRODUCTION TO THE HUMAN BODY

SURVIVAL NEEDS

1. Nutrients


2. Oxygen


3. Water


4. Body Temperature


5. Atmospheric Pressure



HOMEOSTASIS

   The body attempts to maintain a relatively constant internal environment by
    minimising changes that do occur.
