Abstract

Our knowledge on the physiologic evolution of the cardiovascular system is fragmentary. The reptiles and the snakes in particular represent a stage where our knowledge is especially poor. The present study deals with the circulatory dynamics of the snake heart. It may be suggested that the snake heart effectively prevents extensive mixing of arterial and venous blood. The durations of ventricular filling and contraction differ greatly from that in the mammalian heart.
