This is a reticular type of connective tissue that is found on the spleen. The mesh-like structure is formed when thin branching fibers from this tissue network together. The spleen receives its support from reticular fibers that represent a collagen fiber network. Reticular fibers exist in the spleen to organize the lymphocytes and macrophages that also take part in immune functions. These transparent fibers maintain a fine spider-web structure which performs as blood filtration to capture blood-borne foreign materials as well as dead cells and pathogens. This structural network functions as the spleen’s vital basis to perform blood filtration functions and immune reactions. The photo illustrates how reticular fibers create a sturdy yet adaptable structure which maintains essential spleen body function.

A particular kind of reticular connective tissue found in the spleen provides its cells with a supporting structure. Reticular fibers, which are thin, branching collagen fibers, form a network within this tissue that resembles a mesh. This structure supports immune cells that fight infections and aids in blood filtering by capturing aging or damaged red blood cells. The spleen's function in blood filtration and immunological defense depends on the reticular connective tissue.

Reticular connective tissue in the spleen forms a delicate, mesh-like stroma that provides structural support for blood cells and immune cells, facilitating their organization and function within the organ. This network enables the spleen to effectively filter blood, remove old or damaged red blood cells, and support immune responses by hosting lymphocytes and macrophages.
