Connective tissue

Connective tissue - tissue internal environment of the body performing the trophic, metabolic, protective and support function. In addition, connective tissue performs plastic functions (regeneration, wound healing). Characterized by organosilicate and a high diversity of species (blood, subcutaneous tissue, ligaments, tendons, cartilage, bones, and so on). Despite the morphological differences, all kinds of connective tissue composed of cells and intermediate substances, including fiber and base material. Depending on the functions performed by different types of connective tissue, the number, the ratio of cellular structure and the degree of mobility of cells and texture, composition and organization of transitional substances are changed (see the Bone, Blood, Cartilage).
The most common type actually connective tissue is friable fibrous connective tissue that fills the gaps between all bodies and included in their composition. Its cellular elements (fibroblasts and fat cells) participate in the development of intermediate substances, provide protection function (histiocytes, white blood cells and plasma cells), and fat cells deposited neutral fats. A required component of loose connective tissue are the endothelial cells, as well as adventitious cells are a source of formation of different cellular forms of connective tissue. The main substance of loose connective tissue is an unstable gel, which consists of water, proteins and mucopolysaccharides. In the main substance are collagen and elastic fibers.
