animal physiology


Animal physiology is a branch of physiology, which is responsible for studying the biological functioning of different animal species. These analyzes can be performed at the organ level or at the cellular level. In this way, after carrying out the physiological study, the person will be able to have a greater understanding of the behavior of an organ or tissue and, in general, understand the reason for animal behavior.

The word physiology comes from the Greek “physis” which means nature and “logos” which means “study”, so physiology is the study of nature, specifically the functioning of living beings, in this case how animals function.

Animal physiologists look at the structure and function of the various parts of an animal and how these different parts work together to enable animals to enhance their normal behavior and respond to their environment.

One of the most common factors within animal physiology is diversity. Millions of different animal species coexist on earth, and each one of them has adopted, through evolution, unique and innumerable characteristics. Every physiological process results from the hard-to-genetically regulate tissue activities of countless cells.

Despite this great diversity, many points in common can be found within physiology, which unite themes adaptable to all physiological processes, some of them are: they obey physical and chemical laws. They are regulated to keep internal conditions within reasonable limits. The physiological state of an animal is part of its phenotype, which is caused by the gene product or genotype and its interaction with the environment. The genotype is the result of evolutionary change in a set of organisms, populations or species, over many generations.

Mostly these studies investigate the effect of different processes on the physiological phenotype of an animal. Both the genotype of an organism and its environment interact during its development to create the phenotype of an adult organism. The phenotype represents the result of processes at many levels of biological structure (cellular, organ, biochemical, tissue), all these processes together interact to form behaviors, complexes and physiological responses. Similarly, the environment plays an important role since it can influence the adult phenotype.

An animal’s physiology can play a role in its reproductive success. The various lifestyles that different phenotypes lead can result in an evolutionary change in the physiology of a population over many generations.
