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.
Is epithelial tissue a protective tissue?
Epithelial tissue covers and protects many organs and cavities within the body. … In skin, many layers of epithelial cells are present to prevent wear and tear. Hence, it acts as a protective tissue in the animal body.
How does epithelial tissue protect the body?
Epithelial tissues provide the body’s first line of protection from physical, chemical, and biological damage. The cells of an epithelium act as gatekeepers of the body, controlling permeability by allowing selective transfer of materials across its surface. All substances that enter the body must cross an epithelium.
What epithelial tissue protects?
Epithelial tissue also helps to protect against microorganisms. The skin is the body’s first line of defense against bacteria, viruses, and other microbes. Epithelial tissue functions to absorb, secrete, and excrete substances. In the intestines, this tissue absorbs nutrients during digestion.
Why is epithelial tissue considered as protective tissue?
Explanation: The epidermis is considered a protective tissue because its prime purpose is to form a physical barrier between the outside and inside of the body. On the top stratum (layer) of the epidermis, the cells are dead, and so have no physiological function besides to form a barricade against the outside.
Is it true that epithelial tissue is protective tissue in animal body?
a) yes epithelial tissue is protective tissue in animal body..
What are five general characteristics of epithelial tissue?
Despite there being many different types of epithelial tissue all epithelial tissue have just five characteristics, these are cellularity, polarity, attachment, vascularity, and regeneration.
What body part contains epithelial tissue?
Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. An example is the epidermis, the outermost layer of the skin.

What are the main characteristics of epithelial tissue?
Despite there being many different types of epithelial tissue all epithelial tissue have just five characteristics, these are cellularity, polarity, attachment, vascularity, and regeneration. Cellularity as the name suggests means that the epithelium is made up almost entirely of cells.
What are the classification of epithelial tissue?
Simple epithelial tissues are generally classified by the shape of their cells. The four major classes of simple epithelium are: 1) simple squamous; 2) simple cuboidal; 3) simple columnar; and 4) pseudostratified.
What are the three main components of connective tissue?
Components of connective tissue
All forms of connective tissue are composed of (1) extracellular fibres, (2) an amorphous matrix called ground substance, and (3) stationary and migrating cells. The proportions of these components vary from one part of the body to another depending on the local structural requirements.
What is false epithelium?
The nucleus is present at the base in the cells of simple columnar and ciliated columnar cells, except in the case of pseudostratified epithelium where the nuclei appear at different levels within the same layer of cells, giving it a false layered or stratified appearance.
Which tissue is known as protective tissue in human body?
epidermis tissue is also known as protective tissue .
Which animal epithelial tissue is called pavement epithelium where is it located?
Answer: Simple squamous epithelia are found in capillaries, alveoli, glomeruli, and other tissues where rapid diffusion is required. Cells are flat with flattened and oblong nuclei. It is also called pavement epithelium due to its tile-like appearance.
