Lung-Kidney Dual Functions of Fish Gill - Abstract
Substantial published evidence supports the notion that besides the O2/CO2 exchange, gill is also a dominant site of ammonia excretion of fish. Therefore, fish gill plays lung-kidney dual functions of human beings. Comparison of traditional Chinese medicine and fish medicine shows that fish gill occupies “ Metal” and “Water” elements which are generating interaction relationship in the “Wu-xing ring”, indicating that the dual functions are closely related. The dual functions are also supported by the observations that many diseases associated with gill normally cause pulmonary-renal syndromes of fish.
