What does the study of anatomy focus on in animals?

The study of anatomy in animals primarily focuses on understanding the structure of animals. This includes examining the various systems within an organism, such as the skeletal, muscular, circulatory, and nervous systems, as well as the relationships between different organs and tissues. By exploring these structures, scientists and veterinarians can gain insights into how animals function, how they develop, and how they can be affected by diseases. It is a foundational aspect of biology that informs various fields, including veterinary medicine, comparative physiology, and evolutionary biology. The other options pertain to different aspects of animal science: behavior, nutrition, and ecology, which do not directly involve the structural study that anatomy encompasses.
