Anatomy textbooks aren't anything like real life. They're all colourful, clearly distinguished and clearly labelled, yet any autopsy will reveal a mess of reddish brown that tangles and squishes together. Also remember that human bodies aren't constructed, they're grown, so the idealised version of the textbook isn't what you end up seeing when you cut something open, and what you see when you do that changes each time you do that. It's why cadavers are still used to teach medical students.
