The visceral peritoneum is a collagenous membrane made of bands consisting of collagen and meshed fibres that provide support for two of import splenic parenchyma structures, the make unclouded pulp and the red p ulp. Long protrusions called trabeculae of ! the capsule extend interiorly into the organ. The stroma of the spleen consists of the capsule and its protruding trabeculae, reticular fibres, and fibroblasts.
