This clear, readable, and student-friendly text delivers need to know disease content, along with the essential foundation in science that nursing, physician assistant, pharmacology, advanced health science, and medical students need to succeed in their future careers. Approaching the topic as an exploration of pathophysiology, the book relates normal body functioning to the physiologic changes that occur as a result of disease and provides concise yet complete coverage of how the body works. The Fourth Edition builds on the book's extremely successful art program and the Understanding feature and incorporates summary concept boxes after each section. Cover is slightly worn and curled at corners. This is NOT an ex-library book, and is free of annotations and inscriptions.
