The wonderful world of animals
Animals inhabit almost every part of the biosphere. Animal physiology is the study of animal functions and bodily processes.
Animals inhabit almost every part of the biosphere. Animal physiology is the study
of animal functions and bodily processes. The term anatomy refers to the science
that deals with the form and structure of animals.
Physiology deals with the study
of functions of the animal body or any of its parts. A thorough knowledge of the
structure of an animal imparts a lot of information about the various functions
it is capable of performing. This topic is intended to give an overview of both
the anatomy and physiology of some animals (earthworm, cockroach, frog and rat).
Knowledge of physiology is obtained by accurately observing the activities of the
organs, organ systems, tissues, and cells of living animals and plants. Experiments
are usually conducted upon an organ or other part in order to determine how altered
conditions affect its physiological activities. In addition, the activities of healthy
organs are often compared with those of diseased ones. Much knowledge of human physiology
has been obtained by studying animals. Many physiological processes (such as digestion,
assimilation, and respiration) are essentially chemical and physical in nature which
are very important for normal functioning of the body.
