The extracellular matrix of connective tissue consists of ______

The extracellular matrix (ECM) of connective tissue consists of several key components that provide structural and biochemical support to surrounding cells.

1. Fibers: Collagen, elastin, and reticular fibers are the primary types. Collagen provides tensile strength, elastin offers elasticity, and reticular fibers support the framework of organs.

2. Ground Substance: This is a gel-like material that fills the space between cells and fibers. It consists of water, glycoproteins, proteoglycans, and other substances that facilitate the exchange of nutrients and waste between blood and cells.

3. Cells: While the ECM mainly refers to the non-cellular components, it also includes various resident cells such as fibroblasts (which produce collagen and other fibers), macrophages (which provide immune responses), and adipocytes (fat cells).

Together, these components enable the extracellular matrix to play essential roles in tissue integrity, strength, flexibility, and biological functions such as cell signaling and growth.
