Hello there! I have been looking for the cartoon for a while, so it would be a miracle to finally get the name of it. There is a family each member of which explains one thing or another of a particular field. I remember the mother talking about anatomy, so that she took her children and explore the body’s inner world like an adventure. It was on more than fifteen years ago when I was a schoolboy and watched it before the Adventures of Oliver Twist in which the story was told from a dog’s point of view, but I do not know whether it was on the same channel or not.
