comparative anatomy: the study of relationships between the anatomies of different species developmental anatomy: the study of the anatomical changes an animal undergoes in the process of growth

One common approach to the study of anatomy is from the viewpoint of a classification system that is based on the type of organisms studied, generally plant anatomy and animal anatomy. Animal anatomy can be further subdivided into human anatomy and comparative anatomy. Other anatomy subdivisions are developmental, pathological, and surgical anatomy and anatomical art. An example of developmental is the study of embryos, and an example of pathological is the study of diseased organs. Examples of applied anatomy are surgical anatomy and anatomical art. Anatomy encompasses the following systems: musculoskeletal, nervous, circulatory, immune, respiratory, digestive and excretory, endocrine, reproductive, and integumentary. These systems differ widely among animals, but most animals need to fulfill the functions of these anatomical structures in one way or another. For simplicity's sake, anatomy of warm-blooded vertebrate creatures will be discussed here.
