The morphology of hemolymph circulatory systems has been studied in many arthropod groups over the past decades. In most cases, however, the focus of these studies has been the vascular system, while its counterpart, the lacunar system, has often been neglected. To further understanding of the interrelationships between these two complementary subsystems, we investigated both, the hemolymph vascular system and the hemolymph lacunar system, of the decapod Penaeus vannamei using 3D‐imaging techniques (micro‐computed tomography and confocal laser scanning microscopy) in combination with 3D reconstruction. Major parts of the vascular and lacunar system are described. Our insights into their morphology are used to derive functional conclusions for a model illustrating the interrelationships between the two subsystems. The morphology of and the functional interaction between the vascular and lacunar systems are discussed in the context of the debate on “open vs. closed circulatory systems.”

南美白对虾的循环系统，1931-腔隙功能和对“开放系统与封闭系统”辩论的重新考虑

在过去的几十年里，已经在许多节肢动物群中研究了血淋巴循环系统的形态。然而，在大多数情况下，这些研究的重点是血管系统，而其对应物腔隙系统则经常被忽视。为了进一步了解这两个互补子系统之间的相互关系，我们使用 3D 成像技术（显微计算机断层扫描和共聚焦激光扫描显微镜）结合研究了十足目南美白对虾的血淋巴血管系统和血淋巴腔隙系统。 3D 重建。描述了血管和腔隙系统的主要部分。我们对其形态的洞察用于得出模型的功能结论，该模型说明两个子系统之间的相互关系。
