Question

Write the location and function of the
following epithelial tissue :
a.squamous epithelium
b. Stratifiedepithelium
C. columnar epithelium
d.Cubdolal epithelium
e. glandular epithelium​

Answer 1

Answer:

1.) Epithelial tissues are widespread throughout the body. 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.

2.)Stratified epithelia are more durable and protection is one their major functions. Since stratified epithelium consists of two or more layers, the basal cells divide and push towards the apex, and in the process flatten the apical cells.

3.)The main function of simple columnar epithelial cells are protection. For example, the epithelium in the stomach and digestive tract provides an impermeable barrier against any bacteria that could be ingested but is permeable to any necessary ions

4.) Simple cuboidal epithelium is found in glandular tissue and in the kidney tubules. Simple columnar epithelium lines the stomach and intestines. ... Transitional epithelium can be distended or stretched. Glandular epithelium is specialized to produce and secrete substances.

5.) Glandular epithelial cells make up any glands within the body. Examples include sebaceous glands of the skin and glands in the intestinal lining (exocrine glands), and many endocrine glands releasing hormones, such as the thyroid follicle.
