Answer:
The extra cellular matrix (ECM) of connective tissue consists of various organic and inorganic compounds. The organic component of the ECM includes collagen fibers, elastin fibers, proteoglycans, and other proteins. The ECM also contains various inorganic electrolytes, such as calcium and magnesium ions, and water. Together, these components play a crucial role in the structure, function, and mechanics of connective tissue, providing support, elasticity, and strength to the tissue.
