Question

Quizplus · Accepted Answer

The extracellular matrix of connective tissue is composed of three major components: protein fibers, ground substance, and fluid. Protein fibers provide structural support, while ground substance acts as a filler and helps to facilitate nutrient and waste exchange between cells and blood vessels. Fluid helps to maintain proper hydration and lubrication of the tissues. Carbohydrates, lipids, and phospholipids may be present in smaller amounts but are not major components of the extracellular matrix. Glycoproteins may be present in the ground substance but are not one of the three major components.
