Animal physiology is the scientific study of animals' or their components' life-sustaining qualities, functions, and processes. Temperature, blood flow, and hormone regulation are just a few of the main homeostatic mechanisms covered by this discipline. Animal physiology and biology (often known as zoology) is a broad field of study in the biological sciences that deals with the structure and function of animals as well as how they interact with their surroundings. Animal physiology is the study of how animals’ function and the basic processes that allow animals to live. From membranes to organelles, cells, organs, organ systems, and the entire animal, these processes can be investigated at various levels of organisation. Animal physiology is the study of how biological processes work, how they operate in different environments, and how they are regulated and integrated. Animal physiology is intertwined with anatomy (the relationship between function and structure) and the fundamental physical and chemical laws that govern both living and non-living systems.
