Reticular connective tissue is associated with hematopoietic organs such as bone marrow, lymph nodes, and spleen.

• A. Cartilage
• B. Liver
• C. Bone
• D. Hematopoietic organs (bone marrow, lymph nodes, spleen)

Answer: (D)

Reticular connective tissue provides a delicate, three-dimensional scaffold (stroma) made of reticular fibers that supports cells in certain organs. The fibers, largely type III collagen, form a network that holds developing blood cells and lymphocytes in place, allows movement and interactions between cells, and helps create spaces for immune and hematopoietic activity. This reticular framework is the defining feature of hematopoietic organs such as bone marrow, lymph nodes, and spleen, where it supports the organization and function of blood-forming and immune cells. Other tissues don’t rely on this reticular scaffold as their main structural framework. Cartilage, for example, is built around a cartilage matrix with chondrocytes; bone is mineralized tissue with a rigid matrix; the liver is composed mainly of hepatocytes with a different connective-tissue organization. Thus, the reticular network is most characteristic of hematopoietic organs.
