Which type of epithelium lines the blood vessels and the heart chambers, and is also called the endothelium?
simple squamous epithelium

Which type of epithelium when viewed under a microscope appears to have cube-shaped cells organized into rings to form ducts and tubules?
simple cuboidal epithelia

What is the function of the basement membrane (also known as the basal lamina)?
A. Attaches skin to muscle below.
B. Provides an impenetrable barrier that protects the underlying tissues.
C. Adheres the superficial epithelial tissues onto underlying connective tissue.
D. Provides nutrients and other vital substances to the avascular epithelium.
C. Adheres the superficial epithelial tissues onto underlying connective tissue.

Which type of epithelial cell is flat and irregularly shaped and typically functions in protection, secretion, or diffusion?
Squamous

The lungs and blood vessels are areas in which rapid diffusion of gases and/or nutrients must occur. Based on anatomical structure, which type of tissue is most logically found in these areas?
Simple squamous epithelium

Which type of tissue lines most of the gastrointestinal tract and the gallbladder?
Simple columnar epithelium

Which type of tissue is located in the thyroid gland and renal tubules?
Simple cuboidal epithelium

Which type of epithelium is found in parts of mammary glands?

stratified columnar epithelium

Which type of epithelium is found in parts of mammary glands?
stratified columnar epithelium

While observing a tissue under the microscope, you notice two layers of cells that are more square shaped than round. How would you classify this tissue?
Stratified cuboidal epithelium

While observing a tissue under the microscope, you notice a few layers of column-shaped cells. The nuclei located within the cells are fairly evenly dispersed in the middle of the cell or closer to the basal surface. How would you classify this tissue?
Stratified columnar epithelium

Which type of tissue provides a physical barrier that functions to protect against abrasion and attacks by pathogens and chemicals?
Stratified squamous epithelium

Which type of epithelium is found lining the urinary bladder?
transitional epithelium

What lines the nasal cavity, trachea, and bronchi?
Pseudostratified ciliated columnar epithelium


Goblet cells are located in the pseudostratified ciliated columnar epithelium
lining the respiratory tract and in the simple columnar epithelium found in the stomach and small intestine. What is the function of goblet cells?
Goblet cells function as a unicellular mucus-secreting gland.

What is the advantage to having transitional epithelium lining the urinary bladder?
Transitional tissue allows the urinary bladder to stretch when filled with urine and then shrink back to its original shape when the bladder is emptied.

Epithelia are classified and identified by ________ and ____________.
A. function; general shape
B. number of cell layers; general shape
C. number of cell layers; function
D. none of the above
B. number of cell layers; general shape
