EXERCISE 2-B
Classification of Tissues
Tissue Structure and Function: General Review
1. Define tissue: group of cells with similar structure and function
2. Use the key choices to identify the major tissue types described below.
Key: connective epithelium muscular nervous
epithelium 1. lines body cavities and covers the body’s external surface
muscle 2. pumps blood, flushes urine out of the body, allows one to
swing a bat
nervous 3. transmits waves of excitation
connective 4. anchors and packages body organs
epithelium 5. cells may absorb, protect, or form a filtering membrane
nervous 6. most involved in regulating body functions quickly
muscle 7. major function is to contract
connective 8. the most durable tissue type
connective 9. abundant nonliving extracellular matrix
nervous 10. forms nerves
Epithelial Tissue
3. On what bases are epithelial tissues classified? according to the shape of the cells and
number of the cell layers formed.
4. How is the function of an epithelium reflected in its arrangement?
- They are reflected in the arrangement of fitting closely together to form intact sheets
of cells since the epithelium cells function to form linings or covering membranes.

, 5. Where is ciliated epithelium found? What role does it play?
- the ciliated epithelium is found in the airways, the uterus, and the fallopian tube. It
performs the function of moving particles or fluid over the epithelial surface. It also
functions in absorption or secretion.
6. Transitional epithelium is actually stratified squamous epithelium, but there is something
special about it.
- The shape of cells of the transitional epithelium depends upon the amount of
stretching and it has the ability to stretch and return to its normal shape.
7.Using the key, choose the type of epithelial tissue that best fits each description. Some
responses may be used more than once.
Key: pseudostratified ciliated columnar simple cuboidal stratified squamous
simple columnar simple squamoustransitional
pseudostratified ciliated columnar 1. lines much of the respiratory tract
pseudostratified ciliated columnar 2. stretches
simple cuboidal epithelium 3. lines the small and large intestines
stratified squamous epithelium 4. best suited for areas subject to friction
simple cuboidal epithelium 5. propels substances across its surface
squamous epithelial cells 6. most suited for rapid diffusion
simple cuboidal epithelium 7. tubules of the kidney
Connective Tissue
8. What is the makeup of the matrix in connective tissues?
- The matrix in the connective tissue is made up of living cells and non-living
substances called the ground substance. The cell, fibers and ground substance make
up the extracellular matrix.
