#1
What is the primary function of epithelial tissues?
Secretion and absorption
ExplanationEpithelial tissues primarily function in secretion and absorption.
#2
What is the function of microvilli in epithelial cells?
Increase surface area for absorption
ExplanationMicrovilli in epithelial cells increase the surface area for enhanced absorption.
#3
Which epithelial tissue is found in the lining of the small intestine, aiding in nutrient absorption?
Simple columnar epithelium
ExplanationSimple columnar epithelium is found in the lining of the small intestine, aiding in nutrient absorption.
#4
Which of the following epithelial tissues is responsible for forming the epidermis of the skin?
Stratified squamous epithelium
ExplanationStratified squamous epithelium is responsible for forming the epidermis of the skin.
#5
Which type of epithelial tissue is specialized for stretching and recoiling, as seen in the urinary bladder?
Transitional epithelium
ExplanationTransitional epithelium is specialized for stretching and recoiling, as seen in the urinary bladder.
#6
Where is simple squamous epithelium primarily found?
Alveoli of the lungs
ExplanationSimple squamous epithelium is primarily found in the alveoli of the lungs for efficient gas exchange.
#7
Which of the following is a characteristic of stratified epithelium?
Multiple layers of cells
ExplanationStratified epithelium is characterized by having multiple layers of cells.
#8
Which of the following glands produces oily, sebaceous secretions?
Sebaceous glands
ExplanationSebaceous glands produce oily, sebaceous secretions.
#9
What is a characteristic feature of pseudostratified columnar epithelium?
Ciliated cells
ExplanationPseudostratified columnar epithelium is characterized by ciliated cells.
#10
What is the primary function of tight junctions in epithelial tissues?
Anchoring cells together
ExplanationTight junctions in epithelial tissues function in anchoring cells together, forming a barrier.
#11
What is the role of goblet cells in epithelial tissues?
Secrete mucus
ExplanationGoblet cells in epithelial tissues play the role of secreting mucus.
#12
Which type of epithelial tissue lines the urinary bladder?
Transitional epithelium
ExplanationThe urinary bladder is lined by transitional epithelium, allowing for expansion and contraction.
#13
Which type of epithelial tissue is best suited for areas with high friction and wear?
Stratified squamous epithelium
ExplanationStratified squamous epithelium is best suited for areas with high friction and wear, providing protection.
#14
What is the primary function of cilia in respiratory epithelium?
Movement of mucus
ExplanationCilia in respiratory epithelium primarily function in the movement of mucus.
#15
In stratified epithelium, where is the newest layer of cells located?
At the bottom surface
ExplanationIn stratified epithelium, the newest layer of cells is located at the bottom surface.
