Anatomy is the study of form and structure of organisms, whilst physiology is the study of the function of an organism and the processes, physical, chemical and biological, occuring within it. All higher organisms are built from cells, starting as a single cell (in the form of fertilized egg or ovum) and developing into a more complicated multicellular organism. As cells divide and grow they differentiate into tissues with a variety of functions. The tissues normally found in an animal's body are: muscle, connective, nerve, epithelial and fluid. They are grouped together to form the organs, any given organ consisting of two or more kinds of tissue. Organs are organized into bodily organ systems that carry out some major function of the body. Although the systems are similar in structure and function among all species, there are differences in the detail of bodily systems among species. The greatest differences regarding farm common farm animals appear to be between mammals and poultry. This comprehensive book focuses on the gross anatomical structures of major farm animals. The book is aligned perfectly with the needs of a new generation of students.
