Animal anatomy is also a specific field of general anatomy, which is interested in the anatomy of animals, different from the human one. It is the study of various factors that influence and determine the form, structure, and function of different body parts. Physiology is the study of how the components of the body function, and biochemistry is the study of the chemistry of living structures. The advances in clinical medicine show us that our bodies still hold many secrets. This is because the knowledge of ones own body and the body of other living beings is the basis of many forms of their manipulation or our interaction with them. Ocular examination findings vary depending on degree and area of vessel persistence. Since Darwins time, the study of comparative anatomy has centred largely on body structures that are homologousi.e., ones in different species that have the same evolutionary origin regardless of their present-day function.
