Verified step by step guidance

Understand the role of the extracellular matrix (ECM) in connective tissues. The ECM provides structural and biochemical support to the surrounding cells.

Identify the common components of the ECM. Typically, the ECM is composed of fibers and ground substance.

Recognize the types of fibers found in the ECM. The most common fibers are collagen fibers, which provide strength and support, and elastic fibers, which allow for flexibility.

Define ground substance. It is the amorphous, gel-like component of the ECM that fills the space between cells and fibers, providing a medium through which nutrients and waste can diffuse.

Evaluate the options given in the problem. Collagen fibers and ground substance are the two components that are commonly found in the ECM of all connective tissues.
