ELI5: Why is trans-fat bad for our body, but not saturated fats?

I had been reading the book, "The Great Cholesterol Myth" and came across this. But I can't find any scientific reason online why this is so. Thanks.

Trans fats have two double bonds in their carbon chain. essentially, this means that they are more rigid. In your blood, a build up of trans fats would be similar to tossing a bunch of ladders into a pile randomly: they can't maneuver past one another and will form a large buildup. This blocks the passage of blood, which can be dangerous. Saturated fats don't have these rigid double bonds and by contrast would be similar to throwing a bunch of rope into a pile.
