Epithelial Tissues Flashcards
(26 cards)
What are epithelial tissues?
Epithelial tissues are layers of cells that cover the body surfaces, line cavities and organs, and form glands.
True or False: Epithelial tissues are avascular.
True
What is the primary function of epithelial tissues?
The primary function is to protect, absorb, secrete, and sense.
Fill in the blank: Epithelial tissues are classified based on the number of layers and the shape of the cells. The two main types based on layers are ___ and ___ epithelium.
simple, stratified

What is the function of glandular epithelium?
To produce and secrete substances such as hormones, enzymes, and mucus.
Fill in the blank: Epithelial tissues are anchored to underlying tissues by a structure known as the ___ membrane.
basement

What is the function of microvilli in epithelial cells?
Microvilli increase the surface area for absorption.
True or False: Epithelial tissues are innervated and can sense stimuli.
True
What is the difference between exocrine and endocrine glands?
Exocrine glands secrete substances onto epithelial surfaces via ducts, while endocrine glands secrete hormones directly into the bloodstream.
