1. Which function of glandular epithelial cells involves producing and releasing substances?
A.
Secretion
B.
Movement
C.
Support
D.
Contraction
Correct Answer:
Secretion
Explanation:
Glandular epithelial cells are specialized to produce and release substances, so their main function is secretion.
2. Which type of epithelial tissue is mainly specialized for secretion?
A.
Glandular epithelium
B.
Ciliated epithelium
C.
Squamous epithelium
D.
Transitional epithelium
Correct Answer:
Glandular epithelium
Explanation:
Glandular epithelium consists of cells adapted to produce and secrete substances such as enzymes, hormones, or mucus.
3. Which substance may be secreted by glandular epithelial cells?
A.
Mucus
B.
Bone
C.
Muscle fibres
D.
Nerve impulses
Correct Answer:
Mucus
Explanation:
Some glandular epithelial cells secrete mucus, which helps protect and lubricate epithelial surfaces.
4. The epithelial cells of glands are primarily involved in which activity?
A.
Secretion of useful substances
B.
Transmission of nerve impulses
C.
Pumping blood
D.
Producing body movement
Correct Answer:
Secretion of useful substances
Explanation:
Glandular epithelial cells form glands and release substances needed for various body functions.
5. Which type of gland releases its secretion through a duct?
A.
Exocrine gland
B.
Endocrine gland
C.
Sensory gland
D.
Contractile gland
Correct Answer:
Exocrine gland
Explanation:
Exocrine glands secrete their products through ducts onto a surface or into a body cavity.
6. Which type of gland releases hormones directly into the blood?
A.
Endocrine gland
B.
Exocrine gland
C.
Digestive duct
D.
Sweat pore
Correct Answer:
Endocrine gland
Explanation:
Endocrine glands are ductless and release hormones directly into the bloodstream.
7. The secretion of digestive enzymes by epithelial cells is an example of which function?
A.
Secretion
B.
Protection
C.
Absorption
D.
Locomotion
Correct Answer:
Secretion
Explanation:
Digestive enzymes are produced and released by specialized glandular epithelial cells, making this a secretion function.
8. Which glandular epithelial secretion helps keep the lining of some organs moist?
A.
Mucus
B.
Keratin
C.
Calcium phosphate
D.
Hemoglobin
Correct Answer:
Mucus
Explanation:
Mucus secreted by glandular epithelial cells helps keep surfaces moist and may also protect them.
9. Salivary glands are examples of glands that perform which function?
A.
Secretion into ducts
B.
Direct nerve conduction
C.
Formation of bones
D.
Muscle contraction
Correct Answer:
Secretion into ducts
Explanation:
Salivary glands are exocrine glands that secrete saliva through ducts into the mouth.
10. Which statement best describes the secretion function of epithelial tissue?
A.
It produces and releases substances such as mucus, enzymes, or hormones.
B.
It carries oxygen through blood vessels.
C.
It joins bones together at joints.
D.
It generates voluntary body movements.
Correct Answer:
It produces and releases substances such as mucus, enzymes, or hormones.
Explanation:
Specialized epithelial cells perform secretion by producing and releasing substances required for protection, digestion, or regulation.
