What does the epithelial cell do?

They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.

Do epithelial cells produce secretions?

Many epithelial cells are capable of secretion and release mucous and specific chemical compounds onto their apical surfaces. The epithelium of the small intestine releases digestive enzymes, for example.

What tissue do epithelial cells make?

Types of Epithelial Tissue

Epithelial Tissue Cells
Cells	Locations
Simple cuboidal epithelium	In ducts and secretory portions of small glands and in kidney tubules
Simple columnar epithelium	Ciliated tissues including the bronchi, uterine tubes, and uterus; smooth (nonciliated tissues) are in the digestive tract bladder

How do epithelial cells get nutrients?

Epithelial layers contain no blood vessels (avascular), so they must receive nourishment via diffusion of substances from the underlying connective tissue, through the basement membrane. Cell junctions are especially abundant in epithelial tissues.

Covers and lines body surfaces.
Cells are densely packed together with minimal amount of intercellular substance.
Cells are firmly attached by intercellular junctions.
Cells rest on a basement membrane partly derived from underlying connective tissue.

When referring to tissues What does the word simple mean?

The terms simple and stratified describe the number of cell layers in an epithelium (Figure 4.2a). t Simple epithelia contain a single layer of cells, with each. cell attached to the basement membrane. t Stratified epithelia contain more than one layer of. cells.

What is the main function of squamous epithelium?

The primary function of simple squamous epithelia is to facilitate diffusion of gases and small molecules.

What three statements describe epithelial tissue?

Which statements correctly describe epithelial tissue? It is richly innervated, it lacks blood vessels, it has a high regeneration capacity. Of the four types of the body membranes, the two principal types of internal membranes are ” ” and ” ” membranes.
