- Two basic approaches to the study of anatomy:
1. Systemic anatomy is the study of the body by systems and is the approach taken in this and most other introductory books.
- Structural and Functional Organization of the human body:
The body can be studied at six structural levels: the chemical, cell, tissue, organ, organ system, and organism.
As you can see, here is a picture of the Levels of Organization of the body.
- Characteristics of Life
1. Organization - is the condition in which the parts of an organism have specific relationships to each other and the parts interact to form specific functions.
2. Metabolism - is the sum of the chemical and physical changes taking place in an organism.
3. Responsiveness - is the ability of an organism to sense changes in its external or internal environment and make the adjustments that help maintain its life.
4. Growth - results in an increase in size of all or part of the organism.
5. Development - includes the changes an organism undergoes through time; it begins with fertilization and ends at death.
6. Reproduction - is the formation of new cells or new organisms.
- Homeostasis - is the existence and maintenance of a relatively constant environment within the body.
