Chapter 1

2 What does Anatomy mean? Anatomy is the study of the structure and shape of the body and body parts and their relationships to one another. Gross Anatomy Large easily observable structures Microscopic Anatomy Very small structures that need a microscope

3 What does Physiology mean?
Physiology is the study of how the body and its parts work or function.

4 In your groups, discuss the relationship between Anatomy and Physiology.
Ask yourselves… How are the two different? Give examples How are they similar? Describe how they are closely related.

5 Levels of Structural Organization
Atoms Cells Tissues Organ Organ system Organism

6 In your groups, come up with as many organ systems as you can think of.
Nervous system Digestive system Skeletal system Muscular system Cardiovascular system Reproductive system Respiratory system Urinary system Integumentary system Endocrine system Lymphatic system

7 What are necessary life functions that an organism must have to survive?
Maintaining Boundaries Responsiveness Digestion Metabolism Excretion Movement Reproduction Growth

8 What factors must be available in order for an organism to survive?
Oxygen Nutrients (food) Water Appropriate body temperature Appropriate atmospheric pressure

9 What is homeostasis? Homeostasis describes the body’s ability to maintain relatively stable internal conditions even though the outside world is continously changing.

10 What is a homeostatic imbalance?
Homeostatic imbalance is a condition where there is a disturbance in homeostasis. Most disease can be regarded as a result Aging Body organs become less efficient Internal conditions become less stable

11 Anatomical Position Anatomical Position is the standard body position in Anatomy.
