Ascidian inflammatory responses are characterized by an influx of blood cells into areas containing foreign material or injured tissue. The sequestering and removal of foreign substances is a function of their chemical nature and size. Small particulate materials are removed by phagocytosis; substances too large to be phagocytosed are encapsulated. Blood cells involved in inflammatory reactions are small undifFerentiated cells (hemoblasts, lymphocytes), hyaline and granular leucocytes and morula cells.
