What is one of the main functions of the extracellular matrix?

1. To generate electrical impulses

2. To hold cells and tissues together and regulate transport

3. To facilitate nutrient absorption

4. To produce hormones

The correct answer is: To hold cells and tissues together and regulate transport

The extracellular matrix (ECM) primarily serves to hold cells and tissues together and to regulate transport between cells. It is a complex network of proteins and carbohydrates that provides structural and biochemical support to surrounding cells. The ECM plays a crucial role in the organization of tissues, influencing cell behavior, providing mechanical properties, and facilitating communication between cells. This supportive framework helps maintain the shape and integrity of tissues and organs while also serving as a medium for the movement of nutrients, waste products, and signaling molecules. By regulating these interactions and creating an environment conducive to cellular activities, the extracellular matrix is vital for tissue development, repair, and overall health.
