What Is Loose Connective Tissue?

Loose connective tissue refers to a soft and elastic connective tissue. It is mainly filled in the space between various organs or tissues. If the skin is pulled apart when the animal specimen is peeled, thin and transparent loose connective tissue can be seen. The fibers of loose connective tissue are mainly collagen fibers and elastic fibers. Among them, the collagen fibers are bundled, and the stars are arranged in a wave pattern to interweave into a net. The elastic fiber is single-stranded and traverses in various directions. There are many types of cells in loose connective tissue, and the main component is proteoglycan. It also contains a large amount of interstitial fluid. ^[1]

Loose connective tissue is composed of three components: cells, fibers, and matrix. The content of cells and fibers is less, and the content of matrix is more.

By a small number of multiple cells and a large number

Loose connective tissue is soft, elastic and tough. It is honeycomb when viewed with the naked eye, so it is also called areolar tissue. Such tissues are widely distributed in the body, and can be distributed between organs, such as skin and muscle, forming the outer membrane or tube wall of some organs; there is also loose connective tissue filling between tissues and cells; in addition, blood Also belongs to loose connective tissue. The functions of loose connective tissue are mainly support, connection, nutrition, defense, protection and repair of wounds.
