"The Body Had A Head" is by Gustav Eckstein (photo from the back cover, complete with worn bookcover), and is basically an anatomy and physiology book in layman's terms. It was published in 1969, making the science it contains a little out of date, but Eckstein was a great writer. The first chapter is composed entirely of historical essays on the human body from the likes of Socrates and Aristotle. The rest of the book covers almost every major organ system and how everything is all interconnected. Eckstein used very colorful section headings, such as Skull: "Alas, Poor Yorick" and Stomach: More Than a Storage Bin. He also used weird extended metaphors such as Chapter IX. Digestion. It All Works Like a Hungry Dog.

The book is out-of-print, but I've seen many copies in other used bookstores, especially in Boston, MA.

From the back cover:
"Looking back, it seems all indirection. The earliest memories are scanter than other people's, only occasionally a clear one. Cheese -- ridiculous. There was an inborn love of cheese; on a half-dark wintery morning, because it was Christmas, I was permitted to walk what for my legs was miles and when the grocer had weighed the cheese he sliced off a slice from what was my mother's, gave it to me, because it was Christmas, and I could nibble it all the slow way home, and there was the tree.

"My first day of school I do not remember, but a ravine through snow higher than my head, I do. A year then or so, and a teacher, with a paunch, each recess leaned with his rattan from a low window-sill and indiscriminately beat the boys, and from him I learned how to keep out of touch.

"After that I traveled rapidly through high school and Hamlet, almost blocked by a father who believed in neither, assisted by a mother who believed in both. Then a professor of physiology with a glass eye and a long finger pointed to me after his lecture, and when I came down to where he had been standing in the amphitheatre, said severely I should be in the medical school, not in this dental school. So, I was in both. From the latter I earned the money that took me to Harvard briefly, to Europe extensively. Now I was a doctor and a teacher; taught bacteriology, then physiology, then neurophysiology, and after years had the privilege of sitting in seminars of psychiatry. Somewhere in the course of this I had found a pen, and that clarified everything."
