"Principles of Anatomy and Physiology" by Gerard J. Tortora, Bryan H. Derrickson - Ebook

The new edition of Principles of Anatomy and Physiology maintains the superb balance between structure and function. It continues to emphasize the correlations between normal physiology and pathophysiology, normal anatomy and pathology, and homeostasis and homeostatic imbalances. The simple redesign of the twelfth edition allows the illustrations to be the focal point on each page. Each page is carefully laid out to place related text, figures, and tables near one another, minimizing the need for page turning while reading a topic.

Merck Manual 17ed (Centennial Edition)

This is serious stuff. The most widely used medical text in the world and the hypochondriac's bible, the Merck has the lowdown on the vast expanse of human diseases, disorders and injuries, as well as their symptoms and recommended therapy. It's intended for physicians and medical students, but though the type is tiny and the language technical, the Merck's a valuable volume for anyone with more than a passing interest in bodily ills.
