5. The Human Body – An Orientation
Anatomy - structure and shape of the body and its parts
Physiology –how the body and its parts function

6. Anatomy – Levels
1. Gross Anatomy
Large structures
Easily observable

7. Microscopic Anatomy Anatomy – Levels Very small structures
Can only be viewed
with a microscope
Chief cell
Parietal cell

8. Levels of Structural Organization

9. An Introduction to Body Systems
Integumentary
Skeletal
Muscular
Nervous
Edocrine
Cardiovascular
Lymphatic
Respiratory
Digestive
Urinary
Reproductive

10. Integumentary Forms the external body covering
Protects deeper tissue from injury
Synthesizes vitamin D
Location of
Cutaneous nerve receptors (pain-pressure)
Sweat and oil glands
Figure 1.2a

11. Skeletal Protects and supports body organs
Provides muscle attachment for movement
Site of blood cell formation
Stores minerals
Figure 1.2b

12. Muscular Allows: Maintains posture Produces heat locomotion
Manipulation of the environment
Facial expression
Maintains posture
Produces heat
Figure 1.2c

13. Nervous Fast-acting control system of the body
Responds to internal and external changes by:
Activating appropriate muscles and glands
Figure 1.2d

14. Endocrine Glands secrete hormones that regulate processes such as:
Growth
Reproduction
Metabolism (nutrient use by body cells)
Figure 1.2e

15. Cardiovascular The heart pumps the blood
Blood vessels transport blood which carries:
Oxygen
Carbon dioxide
Nutrients
Wastes
The heart pumps the blood
Figure 1.2f

16. Lymphatic
Picks up fluid leaked from blood vessels and returns to the blood
Disposes of debris
Houses WBC’s, involved in immunity
Figure 1.2g

17. Respiratory Keeps blood supplied with oxygen
Removes carbon dioxide from the blood
This exchange occurs through the walls of the air sacs (alveoli) of the lungs
Figure 1.2h

18. Digestive Breaks down food into absorbable units
The nutrients then enter the blood for distribution to body cells
Indigestible food is eliminated as feces
Figure 1.2i

19. Urinary Eliminates nitrogenous wastes
Maintains acid – base balance in the blood
Regulates water and electrolytes
Figure 1.2j
