| Abstract |
The stroke volume of the heart of different sized specimens of a number of crustacean species was derived from the relation between the time constant for temperature equilibration and heart frequency. It appeared that an interspecific relation exists between stroke volume, V, in ml, and fresh weight, w, in grams, which could be represented by the equation: V = 14.73 10-3 W0.815 ml. beat -1. The minute volume in crustaceans is probably linearly related to the animal's body surface, just as the heat transfer constant. The rate of blood flow appears to be closely connected with oxygen consumption as expected from data in literature, though with increasing body weight the blood flow might be slightly lower for a certain oxygen consumption. |
