... 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. * Author...

... lobster microfilament myosin vascular resistance Homarus americanus The circulatory system of decapod crustaceans consists of a single-chambered heart that pumps haemolymph (blood) into an array of seven arteries ( McLaughlin, 1980 ). Muscular cardioarterial valves are present at the origins...

... 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...
