diffusion

Protection: It protects the body tissues from mechanical and physical injury, toxins, radiation and invasion by ______

microorganisms

Absorption: The microvilli found on the surfaces on columnar epithelium cells helps in absorption of nutrients and water through the length of the digestive ______

canal

Secretion: The columnar and cuboidal cells get specialised for secretion and are then referred to as glandular ______

epithelium

Sensation: The sensory cells of the nose, eye and ear that help us in smelling, hearing and seeing are all specialised ______ cells.

epithelial

Transitional Epithelium is thick, composed of several layers, and cell division happens at deeper layers where older cells get pushed up/out. This type of epithelium is found in the epidermis, lines mouth, throat, vagina, and ______.

anus

In the epidermis, keratin causes old cells to harden and die, forming a protective layer. This process known as keratinization causes cells to become tough and dry, keeping water in and chemicals, microbes ______.

out

Transitional Epithelium has 2-3 layers and lines larger ducts like those in mammary glands, sweat glands, salivary glands, and ______.

pancreas

Glandular epithelium is involved in the secretion of various secretory products such as sweat, saliva, breast milk, hormones, and digestive enzymes. It can be found in secretory portions of glands, sweat glands on the skin, and ______ glands.

endocrine

Superficial cells of Transitional Epithelium are elongated while deeper cells (basal layers) are cuboidal. This type of epithelium is found in the male urethra, vas deferens, and parts of the ______.

pharynx

Changes in response to tension, the inner lining of the bladder and urinary passages are stretchy and consist of several layers of cuboidal cells. These cells flatten when stretched and become cuboidal when ______.

relaxed

Learn about the characteristics and functions of transitional epithelium, a type of tissue that is thick and composed of several layers. This type of epithelium undergoes cell division at deeper layers, pushing older cells up and out. Transitional epithelium can be found in various parts of the body, such as the epidermis, mouth, throat, vagina, and anus.
