They are epithelial tissue muscular tissue connective tissue and nervous tissue. However this post will explain only the blood muscle and epithelial tissues in detail.
In the bodies of animals there are 4 major classifications of tissues.
Epithelial tissue in animals. In animals the structure of tissue depends on its function. An animal body is made of four different types of tissues. They have been classified based on the type of cell function and location in the body.
All layers and organs in the body are lined by a group of tissues called epithelial tissues which are commonly. The covering or protective tissues in the animal body are epithelial tissues. Epithelial tissue cells are tightly packed and form a continuous sheet with almost no intercellular spaces.
Permeability of the cells of various epithelia plays an important role in regulating the exchange of materials between the body and the external environment and. Epithelial Tissue Function. Epithelial tissue covers the outside of the body and lines organs vessels blood and lymph and cavities.
Epithelial cells form the thin layer of cells known as the endothelium which is contiguous with the inner tissue lining of organs such as the brain lungs skin and heart. The free surface of epithelial tissue is usually exposed to fluid or the air while the bottom. Animal tissues EPITHELIUM T ogether with connective muscle and nervous tissue epithelium is one of the four basic types of tissues in the animal body.
It accounts for more than 60 of the total cells of the human body. Epitehlium lines the internal cavities and external surfaces of the body. Epithelial Tissue definition.
Epithelial Tissue is one of the four types of tissue epithelial muscular connective and nervous in animals which consists of closely aggregated polyhedral cells adhering firmly to one another forming cellular sheets that line the. Types of Animal Tissue. The different types of animal tissues include.
Epithelial tissues form the protective covering and inner lining of the body and organs. These tissues were the first to evolve during evolution and were first formed during embryonic development. They develop from the ectoderm mesoderm and endoderm of the embryo.
Characteristics of Epithelial Tissues. Types of Animal Tissues. There are 4 main types of animal tissues.
Connective Tissues Muscle Tissues. Lets take a closer look at the functionality of each of the four animal tissues. Epithelial tissue is a thin layer of closely packed cells that cover many organs of our body.
Epithelial tissue or epithelium epi- upon. Thele- nipple is defined as one of the animal tissues that covers both external and internal surfaces of the animal body. It consists of a sheet of tightly packed cells with a minimum of intercellular material and rests upon a non-cellular basement membrane.
All contents of the body including structures and various organs are made of tissues. The animal body comprises of four basic types of tissues all of which vary in their origin and function. Epithelial Tissues - Made of tightly packed cells layer together epithelial tissues line the body surface.
Their functions include protection absorption and secretion. They are Blood Tissue. However this post will explain only the blood muscle and epithelial tissues in detail.
Here are few interesting facts about these 4 animal tissues. Your blood is a liquid tissue. 40 of an animals weight is coming from muscle tissue.
Epithelial tissues cover line protect and secrete. Epithelial tissues include the epidermis of the integument the lining of the digestive tract and trachea and make up the ducts of the liver and glands of advanced animals. The animal kingdom is divided into Parazoa sponges and Eumetazoa all.
Organs are composed of tissues which are in turn composed of cells. Plants have three tissue types. Ground dermal and vascular.
Epithelial connective muscle and bone. Epithelial Tissue Back to Top. Epithelial tissue covers body surfaces and lines body cavities.
Functions include lining protecting and forming glands. Epithelial tissues are animal tissues. These tissues show the characteristics of animal cells.
Here the cells are eukaryotic with a nucleus and have membrane-bound organelles. A cell wall is absent in animal cells. This lack of cell walls gives the animal cells flexibility.
In the bodies of animals there are 4 major classifications of tissues. Epithelial tissue connective tissue muscle tissue and nervous tissue. Epithelial tissue is comprised of layers of tightly packed cells that line the surfaces of the body for protection secretion and absorption.
Examples of epithelial tissue consist of the skin the lining of the mouth and nose and the lining of the. Animal tissues can be divided into four groups according to their functions. They are epithelial tissue muscular tissue connective tissue and nervous tissue.
These tissues are very closely packed and form a continuous protective layer over the surface of organs and inner lining of the body cavity. There are different types of epithelial tissues. Squamous epithelial tissue.
Consists of extremely thin cells that resemble the scales of a fish. Contains cells that appear square in cross-section but are marginally longer than they are wide. Consists of elongated cell involved in.
Epithelial tissue is derived from all three major embryonic layers. The epithelial tissue composing cutaneous membranes develops from the ectoderm. Epithelial tissue composing a majority of the mucous membranes originate in the endoderm.
Epithelial tissue that lines vessels and open spaces within the body are derived from mesoderm. The tissues of multicellular complex animals are four primary types. Epithelial connective muscle and nervous.
Recall that tissues are groups of similar cells group of similar cells carrying out related functions. These tissues combine to form organslike the skin or kidneythat have specific specialized functions within the body. The layer is called as Epidermis and the tissue forming the epidermis is called the Epithelia.

Digestive organs blood vessels kidney tubules and airways. Epithelial tissue usually consists of a single cell layer of cells however in certain cases there may be more than one layer.
