Question

Quizplus · Accepted Answer

Epithelial tissue is primarily responsible for serving as a physical barrier that protects against harmful agents in the environment. This tissue covers exposed surfaces, lines organs and body cavities, and forms glands. It does not have the ability to support and strengthen other tissues, transport substances, or contract to regulate movement. While some sensory receptors are located within epithelial tissue, it is not primarily responsible for detecting changes in the body's environment and elicit an appropriate response.
