There are dissections in school for us to be able to see a real life picture of the different systems. If we didn’t have dissections, all of our visions of the different systems would be in 2-D. Dissection helps us understand how different animals are compared to each other, and dissections show how different their bodies are. It could also help us students with any future job that we want. If somebody was a veternarian, they couldn’t just walk in and give an animal a surgery without training. That would would most likely kill animal. These are my reasons that dissections are needed.
