... in fishes; (2) suggest that IL-1β release at high temperatures may reduce systemic vascular resistance, and thus, the capacity of fish to maintain blood pressure; and (3) provide evidence that both NO and prostaglandins play a role in regulating coronary vascular tone, and thus, blood flow.

... to the fact that vascular resistance was pharmacologically manipulated in these closed-loop studies, conclusions about the vascular limb of the baroreflex response could not readily be made. Few studies have previously dealt with the baroreflex in fish, using open-loop techniques that include both vascular...

... to perfusion of that region. The total vascular resistance placed on the heart when each artery is perfused at a rate typical of in vivo flow rates is approximately 1.93 kPa s ml −1 . All vessels exhibit adluminal layers of fibrils and are relatively compliant at pressures at or below heart systolic pressure...
