Overview of Animal Physiology
Animal physiology is the study of the functions and mechanisms in a living animal. It encompasses a wide range of topics, including cellular processes, organ systems, and the interactions between different biological systems. The third edition of "Principles of Animal Physiology" presents this information through a contemporary lens, highlighting the evolutionary adaptations that influence physiological functions.
Core Concepts and Themes
The book is structured around several core concepts that are crucial for understanding animal physiology:
1. Homeostasis: The ability of an organism to maintain stable internal conditions despite changes in the external environment.
2. Adaptation: How animals evolve physiological mechanisms to thrive in diverse habitats.
3. Integration: The interconnectedness of various organ systems and how they communicate and work together.
4. Comparative Physiology: Understanding physiological differences and similarities among various animal species to draw insights into evolutionary biology.
Structure of the Book
The third edition is organized into clear, coherent sections that facilitate learning and comprehension. Each chapter builds upon the last, providing a solid foundation from which students can explore more complex topics.
