Ch. 36 Objectives

An introduction to Animal Structure and Function

1. Define tissue and explain where it falls in the hierarchy of structural organization.

2. From micrographs or diagrams, correctly identify the following animal tissue, explain how their structure relates to function and give examples of each.

a. Epithelial tissue

1. Cuboidal 2. Columnar 3. Squamous

b. Connective tissue

1. Adipose 2. Cartilage 3. Bone

c. Muscle

1. Skeletal (striated) 2. Cardiac 3. Visceral (smooth)

d. Nervous

3. Describe several body shapes that maximize external surface area in contact with the environment.

4. Explain how animals with complex internal organization and relatively small surface area to volume ratio can have adequate surface area for material exchange with the environment.

5. Describe the location and function of interstitial fluid.

6. Define homeostasis.

7. Distinguish between negative and positive feedback.
