Descriptions
In the top shell, Turbo cornutus, the effects of water temperature on the oxygen uptake at the gill and the oxygen transport with the blood were examined by measuring the amount of oxygen uptake, oxygen utilization (U), ventilation volume(Vg), oxygen partial pressure, oxygen concentration and oxygen saturation of aortic and venous blood, mean oxygen gradient across gill epitherium, oxygen transfer factor of the gill (To_2), volume of cardiac output (Vh), oxygen utilization of the tissues (Ut). The top shell probably coped with the increase in a oxygen demand by the increases of U, Vg, To_2, Vh Ut, when the metabolism increased by the rise of the water temperature.
