| Research Abstract |
Biogenic functions of heat and mass exchange have extremely high efficiencies from the view point of mechanical engineering. Therefore, their bio-mechanisms are needed to be clarified, and useful engineering applications are also expected to be derived from the explanations. This project was carried out for the above purpose, and begun by making a survay of heat and mass exchange configurations in mammals, birds, and fishes. The biogenic heat and mass exchanges are performed mainly in invibo perpheral tissures through the boundary cell menberanes. Blood plays an important role as a heat medium in the case of heat exchange. The blood enters the vessel warm, flows to the extremity of the vasculature where it loses heat to the cold environment corresponding to a significant temperature drop, and then return in a vein that is in close thermal contact with the supply artery. With this countercurrent exchange process functioning, the burden on the metabolism is considerably reduced. Such heat exchange processes are characterized by the micro-circulation system of blood. Various kinds of mass exchanges are also performed in a similar way to the above heat exchange. However, they are able to be functioned through heterogeneous structures of organ issures, together with many chenical reactions and enzyme actions. In addition to these facts, there are so many interesting things to be solved in biogenic heat and mass exchange functions.
