Blood pooled in the pericardial sinus is drawn into the heart through three pairs of ostia (pores) when the heart relaxes ( Figure 32.17 ).

WebIn the case of moderate hypoxia, scallops increase their respiratory and heart rates to maintain aerobic metabolism, which leads to an acceleration of hemolymph circulation [27,120]. However, in severe hypoxia, although the heart rate (HR) is largely increased, the blood flow volume (FV) in tissues drops, which causes the constriction of blood vessels.
