D. diffusion

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

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

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.

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

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?

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

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

What protein does stratified epithelia cells produce?

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

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

What type of epithelium appears to be two layers thick and looks like a doughnut?

Nonkeratinized stratified squamous epithelium is found in all of the following areas of the body EXCEPT the _________.

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?

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?

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

Which type of epithelium is found lining the urinary bladder?

What lines the nasal cavity, trachea, and bronchi?

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?

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

Which of the following is NOT a major category of tissue in the body?
A. bone
B. muscle
B. connective
D. epithelial

This "category" of epithelia is found in areas exposed to abrasion and friction.
