App Description

Discover what happens when physiology fails. Work through interactive lessons that explain the step-by-step breakdown of common cardiovascular, renal, respiratory, gastrointestinal, and musculoskeletal processes. Physiology & Pathology covers 48 physiology topics and 57 conditions, with 50 lessons, more than 5,800 3D models, 38 animations, 16 illustrations, and 26 quizzes.

-Compare 3D models of normal anatomy to models of common diseases and conditions
-Set the heart rate and visualize conduction in a dissectable, beating 3D heart, and follow along on an ECG
-Watch animations that present to the physiological processes of gas exchange, pulmonary ventilation, fluid balance, peristalsis, and more
-Walk through interactive lessons to understand the progression of atherosclerosis, kidney stones, lung cancer, and other common conditions
-Test your knowledge of various physiological processes and pathologies with quizzes

"I can’t wait to teach with this—it is the first time I have seen heart conduction, blood flow, ecg, and heart contractions all together!"
