Chapter 5 Study Guide Answer Key

1. What are the five most important functions of epithelial tissue. protection, sensory function, secretion, absorption, and excretion

2. Identify the four principal tissue types.
epithelial, connective, muscle, nervous

3. Explain how the shape of epithelial cells is used for classification purposes. What are the four types of epithelium described in this classification process? Epithelial cells can be flat and plate-like (squamous).

They can be cube-like (cuboidal).
The cells can be higher than wide (columnar).
They can also be higher than wide with some cells not reaching the membrane (pseudostratified columnar).

4. Classify epithelium according to the layers of cells present. Arrangement of epithelial cells in a single layer is called simple epithelium. If the epithelial cells are layered one on another, the tissue is called stratified epithelium. If the epithelial cells are layered in a relaxed state but can form a single layer when stretched, the tissue is called transitional epithelium.

5. List the types of simple and stratified epithelium and give examples of each. Simple squamous: alveoli, lining of blood and lymph vessels, pericardium, peritoneum Simple cuboidal: glands and ducts, ducts and tubules of the kidney Simple columnar: lining of stomach, intestine,...
