Connective tissue: important functions in the human body

Which is

Connective tissue is one of four major types of body tissue (epithelial, connective, muscular, and nervous). This tissue is found in large quantity in the human body.

Main features

The connective tissue has few cells and matrix in larger volume. The matrix is ​​composed of fundamental substance and fibers. It is richly vascularized, except for ligaments, cartilage and tendons.

Functions

Some of its functions: Provide strength, elasticity and lift; remove worn blood cells (spleen) and microbes (lymph nodes); allow the distension of organs; contribute to joint movement and flexibility and support; etc.

Types

Loose connective tissue, dense connective tissue, cartilage, bone tissue, blood and lymph.

Composition

Connective tissue cells contain fibroblasts, macrophages, mast cells and adipocytes.

The matrix is ​​formed by fundamental substance and fibers. The fundamental substance has the function of holding cells together, and provides a means that actively contributes to cell exchange. The fibers (collagen, elastic and reticular) provide strength and support.
