Epithelial Tissue Types and Functions

Epithelial tissues are classified based on cell shape and the number of layers. Which of the following correctly pairs a description of epithelial tissue with its likely function?

An investigator is examining a tissue sample under a microscope. They observe a single layer of flattened cells lining a blood vessel. Which type of epithelial tissue are they most likely observing?

Which of the following properties of epithelial tissues contributes most directly to its ability to act as a protective barrier?

A scientist is studying a new drug that they believe will stimulate saliva production. To test this hypothesis in vitro, which type of epithelial tissue should the scientist culture?

Epithelial cells in the trachea have cilia that sweep mucus containing debris toward the throat. This is an example of which primary function of epithelial tissue?

Simple Squamous Epithelium

Pseudostratified Ciliated Columnar Epithelium

An organized group of cells working together forms tissue
An organized group of the latter work together to form organs
Tissue that covers a body surface, lines a body cavity, and forms parts of most glands is known as epithelium
Three features that are used to classify epithelia need to be determined
Shapes of epithelial cells found on the surface of epithelia need identification
Specializations found on the apical surface of epithelial cells and their function need specifying
Two specialized forms of epithelia need determination
What separates an epithelium from the underlying connective tissue needs determining
Epithelial cells arranged in a single layer, tall and narrow, with the nucleus located close to the basal side of the cell, are columnar epithelial tissue
Simple squamous epithelial tissue lines the interior of blood vessels
Pseudostratified ciliated columnar epithelial tissue specializes in moving particles across its surface and is found in airways and lining of the oviduct
The epithelium has five identified functions
The epithelium has five identified characteristics
Specifically identify what epithelium lines the Oral Cavity?
Determine what epithelium covers the hard palate and the tongue and the external surface of the gingiva
Identify the epithelium found within salivary glands
A membrane is found inside the oral cavity and where its lubricant formed needs identifying
The difference between an endocrine gland and an exocrine gland needs determining, along with examples of each
Types of epithelium pictured need description

Explore the structure and function of epithelial tissues, including columnar, squamous, and pseudostratified types. Learn about the classification of epithelia and their specializations. Understand how these tissues line body surfaces and cavities.
