This type of tissue covers most exposed areas of the body and lines the body cavities such as blood and lymph vessels, the digestive tract, and glands. These cells function in:
Protection - they form a barrier that is special for their need (like keeping in liquids or allowing the passage of certain materials). Skin cells protect against foreign invasion and permit homeostasis (keeping the internal environment at a certain desired level). This includes keeping certain substances in their proper place in the body, such as blood in vessels and gastric juice in the digestion system.
Structure / support - they line cavities keeping everything in order.
Secretion - certain cells have the task of secretion, these are found scattered in the appropriate epithelial layers (often times in ducts which are in glands).
Epithelial tissue is a major category of animal tissue. It covers the surface of the body, lines body cavities, and forms various glands. Epithelial tissue serves functions such as protection, absorption, secretion, and sensation.

Epithelial tissue: Forms linings and coverings in the body. Connective tissue: Provides support and structure to the body. Muscle tissue: Responsible for movement. Nervous tissue: Enables communication within the body. Adipose tissue: Stores energy in the form of fat.
Epithilial Tissue Lines animal's body Cavity, they can be further subdivided into different types of Epithelial Tissue, depending on what they line
How is the function of nerve tissue different from that of epithelial tissue?
----
No, epithelial tissue does not conduct impulses. Epithelial tissue functions primarily in protection, secretion, absorption, and sensation. Nerve cells, or neurons, are responsible for conducting impulses in the body.
Non-epithelial tissue refers to any type of tissue in the body that is not classified as epithelial tissue. This can include connective tissue (such as bone, cartilage, and blood), muscle tissue (skeletal, smooth, and cardiac), nervous tissue (in the brain and spinal cord), and others. Non-epithelial tissues have various functions in the body, such as supporting, connecting, and transmitting impulses.
The pancreas is an organ. It is one of the unique organs that have both endocrine and exocrine functions.
Epithelial cells are found in epithelial tissue, which is a type of tissue that lines the surfaces and cavities of the body. Epithelial tissue is present in various organs throughout the body, such as the skin, lungs, stomach, and intestines. Epithelial cells play a role in protecting underlying tissues, regulating the passage of molecules, and providing sensory functions.
No, epithelial tissue does not store energy. Epithelial tissue functions mainly in protection, secretion, absorption, and sensation. Energy storage is typically handled by adipose (fat) tissue in the body.
Epithelial tissue exhibits polarity, with distinct apical and basal surfaces. This polarity allows epithelial cells to carry out specialized functions such as absorption, secretion, and barrier formation.
Epithelial tissue forms the lining of various organs in the body. This tissue provides protection, secretion, and absorption functions depending on its location and structure.
Epithelial tissue has the best regenerative ability due to its high turnover rate and constant cell division. Skin and mucous membranes are examples of epithelial tissues that regenerate quickly to maintain barrier functions.
The digestive system is primarily made up of muscular tissue, connective tissue, epithelial tissue, and nervous tissue. Muscular tissue helps with movement of food along the digestive tract, connective tissue provides support and structure, epithelial tissue lines the inner surface for absorption and secretion, and nervous tissue controls and coordinates its functions.
Epithelial tissue always has a "top" (apical surface facing the outside or a body cavity) and a "bottom" (basal surface attached to underlying connective tissue). This arrangement allows epithelial cells to perform functions such as protection, secretion, and absorption efficiently.
