• Which characteristic does epithelial tissue have?

a Highly vascular .

• Slow cell regeneration
• Loose connections among most of its cells
• Anchored in place by a basement membrane

ANSWER: d

FEEDBACK: Incorrect. Epithelial tissue is avascular. See Epithelial Tissue.

• Incorrect. With sufficient nutrients, epithelial cells regenerate quickly. See Epithelial Tissue.
• Incorrect. With the exception of glandular epithelium, specialized cell membrane junctions

bind epithelial cells tightly together at many points. See Epithelial Tissue.

• Correct. Epithelium is anchored in place by a basement membrane thatissecreted by basal

epithelial cells and the underlying connective tissue cells. See Epithelial Tissue.

• Cora is playing with her cat who ends up scratching her. Cora thinks she might need to bandage her skin but notices

that she is not bleeding. Why is this the case?a The claws only scratched the epithelial layer, which is a vascular.

• The cells in the epithelial layer regenerated rapidly from the damage by the claws.
• Loose gaps between the epithelial layer allowed the cat’s claws to pass through without causing damage.
• Basement membrane of the epithelial layer prevented the cat’s claws from penetrating too deeply.

ANSWER: a

FEEDBACK: a Correct. Epithelial tissue is a vascular, which means that is has no blood supply of its own.See Epithelial Tissue.

• Incorrect. Epithelial cells regenerate rapidly but they would not have regenerated completely

within minutes of damage to the skin. See Epithelial Tissue.

• Incorrect. With the exception of glandular epithelium, specialized cell membrane junctions

bind epithelial cells tightly together at many points. See Epithelial Tissue.

• Incorrect. Epithelium is anchored in place by a basement membrane but it is a very thin layer

which would not provide resistance to cat claws.See Epithelial Tissue.

• Which function of epithelial tissue produces hormones, sweat, and enzymes?
• Filtration
• Absorption
• Secretion
• Protection

ANSWER: c

FEEDBACK: a Incorrect. Filtration involves the forcing of fluid through epithelial tissue. One place this occurs is in the kidneys. See Epithelial Tissue.

• Incorrect. Absorption involves the movement of substances through epithelial tissue. For

example, the digestive system is lined with epithelium that nutrients pass through to enter the bloodstream. See Epithelial Tissue.

• Correct. Secretion is a specialty of glandular epithelium which produces substances such as

hormones, sweat, mucus, and enzymes.See Epithelial Tissue.

• Incorrect. The epithelial layer of skin protects the body by being a barrier that keeps bacteria

and chemicals from entering the body. Hormones, sweat, and enzymes are not produced in this process. See Epithelial Tissue.

• A patient is seeing his healthcare professional because he has been losing weight and feeling fatigued. The healthcare

professional determines that malabsorption of nutrients in his small intestine is causing these symptoms. Which tissue layer is most directly involved in the patient’s disorder?

• Connective
• Epithelial
• Muscle
• Nervous

ANSWER: b 2 / 4

Chapter 01 - Tissues of the Human Body Page 3 Anatomy and Physiology for Health Professions 1st Edition Bubb Test Bank

FEEDBACK: a Incorrect. Functions of connective tissue do not influence absorption. They include support, storage, transport, binding, and protection. See Epithelial Tissue.

• Correct. Functions of epithelial tissue include absorption, protection, filtration, and

secretion. See Epithelial Tissue.

• Incorrect. The primary function of muscle tissue is to create body movements. See Epithelial

Tissue.

• Incorrect. The characteristic functions of nervous tissue are its ability to be stimulated

(receive impulses) and its ability to conduct (pass impulses on). See Epithelial Tissue.

5. Epithelial cells that are about as wide as they are tall are called:

• cuboidal.
• stratified.
• squamous.
• columnar.

ANSWER: a

FEEDBACK: a Correct. Cuboidal epithelial cells are cube-shaped, meaning they are about as wide as they are tall. See Classification of Epithelial Tissues.

• Incorrect. Stratified means having more than one layer of epithelial cells. See Classification

of Epithelial Tissues.

• Incorrect. Squamous epithelial cells are flat and hexagonal shaped. See Classification of

Epithelial Tissues.

• Incorrect. Columnar epithelial cells are shaped like columns, meaning they are taller than

they are wide. See Classification of Epithelial Tissues.

• Which type of epithelia is used to filter wastes out of the blood in the kidneys?
• Simple cuboidal 3 / 4

Chapter 01 - Tissues of the Human Body Page 4 Anatomy and Physiology for Health Professions 1st Edition Bubb Test Bank

• Simple squamous
• Stratified squamous
• Pseudostratified columnar

ANSWER: b

FEEDBACK: a Incorrect. Simple cuboidal epithelium is specialized for secretion and absorption, not filtration. Simple cuboidal epithelium does line kidney tubules, but it serves a different purpose. See Simple Epithelia.

• Correct. Simple squamous epithelium is one cell layer thick, making it specialized for

diffusion and filtration in the capillary walls, lungs, and kidneys.See Simple Epithelia.

• Incorrect. Stratified squamous epithelium has more than one layer of cells, andis specialized

to withstand large amounts of friction. The multiple layers of cells do not allow filtration.See Simple Epithelia.

• Incorrect. Pseudostratified columnar epithelium has tall cells. This shape does not allow

filtration. Instead, this type of epithelia is specialized for absorption and secretion. It is found in the male reproductive tract and the ducts of some large glands. See Simple Epithelia.

• Which feature allows epithelial cells to move mucous along the upper respiratory tract?
• Cilia
• Apical layer
• Desmosomes
• Basement membrane

ANSWER: a

FEEDBACK: a Correct. Cilia are projections on the surface some epithelial cells; they create movement that transports molecules. Ciliated pseudostratified columnar epithelium lines the upper respiratory tract. See Simple Epithelia.

• Incorrect. The apical layer of epithelia is the unattached or free side; it is the exposed surface

of the skin or cavity of an internal organ. It does not move substances along the epithelia.See Simple Epithelia.

• Incorrect. Desmosomes are junctions scattered throughout epithelial cell membranes that

prevent the cells from being pulled apart by mechanical stress. They do not move substances along the epithelia. See Simple Epithelia.

• Incorrect. Basement membrane anchors epithelium in place; it does not move substances

along the epithelia. See Simple Epithelia.
