Classification of Tissue

Classification of Tissue

Cells, the basic units of structure and function within the human organism, are organized into groups and layers called tissues.
 

Each type of tissue is composed of similar cells that are specialized to carry on particular functions For example, epithelial tissues form protective coverings and function in secretion and absorption, connective tissues provide support for softer body parts and bind structures together, muscle tissue is responsible for producing body movements, and nerve tissue is specialized to conduct impulses that help to control and coordinate body activities.

In all complex organisms, cells are organized into layers or groups called tissues. Although the cells of different tissues vary in size, shape, arrangement, and function, those within a tissue are quite similar. 

Usually tissue cells are separated by nonliving, inter-cellular materials, which they secrete. These intercellular materials vary in composition from one tissue to another and may take the form
of solids, semi-solids, or liquids. For example, bone tissue cells are separated by a solid inter cellular substance, while blood tissue cells are separated by a liquid.
 

The tissues of the human body include four major types

These tissues are organized into organs that have specialized functions.
