Animal dissections are used in school because they are a good hands-on experience for students.They teach a lot about where body parts are and what they could be used for. I don’t know of many students who would do this type of work at home, and I’m not suggesting anyone to; but this type of work is very vital if you wanted to be in a health career. It is good to know a little bit about functions and where stuff is before you get to college. These are just a few… good reasons why dissections are used in school.
