As the concentration of hydrogen ions (H+) increases, a solution becomes more acidic, and the pH value decreases. As the concentration of hydrogen ion acceptors (such as hydroxyl or bicarbonate ions) increases, a solution becomes more basic, and the pH value increases. Note the pH of some common substances.

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
