Fluorescence Spectroscopy: An Introduction for Biology and Medicine

ment. An introductory section of this chapter deals with criteria of endocrine function and methods and difficulties encountered in studying endocrine problems. This is a useful part of the book and should be of value to the student. Whereas the first two chapters deal at a general level with the topics of osmoregulation and endocrine control, the following chapters cover the function of these two organ systems in the individual vertebrate classes. These chapters provide an excellent, broad, and up-to-date coverage of the comparative aspects of fluid and electrolyte exchange. They are particularly useful in that they not only emphasize the role of endocrine glands in relation to the animal's adjustment to its environment but also cover very adequately what is known about the transport mechanism of fluid and electrolytes at the cellular level of various organ systems.
