... peristaltically rear-to-front(`peristaltic heart'), followed by nearly synchronous front-to-rear constrictions in the contralateral heart segments (`synchronous heart'). Using optical recordings from intact leeches, we now characterize the hemodynamic properties of the cardiac cycle of individual heart segments...

... CVP induced in alligators prevented the collapse of abdominal veins that was apparent during exercise in varanid lizards. Hemodynamic responses to exercise were rapid with peak values attained within 20–40 s after the onset of exercise. Furthermore, hemodynamic responses to exercise were not graded...

... with a microclip. Clipping alters venous return and intracardiac laminar blood flow patterns,with secondary effects on the mechanical load of the embryonic myocardium. We investigated the instantaneous effects of clipping the right lateral vitelline vein on hemodynamics in the stage-17 chick embryo. 32 chick...
