Even we are animals, although we are far more intelligent than most, if not all. Because of their essential relationship with biology, veterinary science is also closely related. A veterinarian, as I said earlier, is someone who cares for an animal. This relationship makes veterinary science a key aspect of the relationship between animal biology. Without veterinarians, we wouldn't know as much about how animals function, even though they function very similarly to us humans based on their place in the animal kingdom.

The word is now widely used in North America and other countries using North America...... middle of paper ...... if all applicants are ever accepted. In these programs, students are required to take courses on animals. anatomy and physiology, as well as the prevention, diagnosis and treatment of diseases. You need to take these subjects and memorize them because students will need them more than anything in their future careers. These programs include 3 years of classroom, laboratory and clinical work. Students typically spend the final year of the 4-year program completing clinical rotations at a veterinary medical center or hospital. They must get used to their future profession and follow a form of apprenticeship with an approved veterinary doctor. Some will even complete internships to continue their studies and gain experience in the field.
