3. What is it? Anatomy: the branch of science that deals with the structure of body parts Physiology: concerns the functions of body parts, what they do and how they do it

4. Levels of Organization Atoms: microscopic particles Molecules: made up of atoms Macromolecules: molecules combined in complex ways Cell: Basic unit of living thing Organelle: structures within a cell that perform a certain task Tissue: Group of cells Organs: Complex structures made up of tissues that perform a certain task Organism: Organs make up living things

6. Characteristics of Life Metabolism: process of chemical reactions in the body that break down substances and build them up for energy Maintenance of Life -Water, Foods, Oxygen, Heat, PressurePressure

7. Characteristics of Life Metabolsim: process of chemical reactions in the body that break down substances and build them up for energy Maintenance of Life -Water, Foods, Oxygen, Heat, PressurePressure Homeostasis: Maintaining a stable internal environment for survival (Temp, pH, water, etc.)

8. Homeostatic Mechanisms Receptors: provide information about specific conditions in the internal environment Set Point: tells what a particular value should be (body temp) Effectors: cause responses that alter conditions in the internal environment

9. Homeostatic Mechanisms Receptors Effectors Set Point

10. Homeostatic Mechanisms Receptors Effectors Set Point Stimulus

11. Homeostatic Mechanisms Receptors Effectors Set Point Stimulus Change is compared to the set point

12. Homeostatic Mechanisms Receptors Effectors Set Point Stimulus Change is compared to the set point

13. Homeostatic Mechanisms Receptors Effectors Set Point Stimulus Change is compared to the set point Response (Change is corrected)

15. Body Portions Axial Portion: Includes head, neck, and trunk

16. Body Portions Axial Portion: Includes head, neck, and trunk Appendicular Portion: Includes upper and lower limbs

17. Anatomical Positions Superior: Body part is above another part, or closer to the head Inferior: body part is lower than another, toward the feet Anterior: Towards the front (Eyes are anterior to the brain) Posterior: Towards the back Medial: Imaginary midline dividing the body into equal right and left halves.

18. Anatomical Positions Lateral: toward the side with respect to the midline (Ears are lateral to the eyes) Ipsilateral: structures on the same side (right kidney and right lung) Proximal: Body part that is closer to the trunk (elbows are proximal to wrist) Distal: Opposite of proximal, farther away from trunk Superficial: placed near the surface of the skin

19. Draw and label your own anatomical person. Use figure 1.13 on page 14 in your text
