Biology 106: Pathophysiology

About the Course

Biology 106: Pathophysiology is designed to be used to prepare you to earn college credit by passing the Pathophysiology Excelsior exam. This course covers topics that are included on the exam, such as cell injury, the cardiovascular system and clinical applications. Use it to help you learn what you need to know about pathophysiology topics so you can succeed on the exam.

The pathophysiology instructors are experienced and knowledgeable educators, who have put together comprehensive video lessons in categories ranging from issues with the immune system to nervous system disorders and from skin pathologies to reproductive system disorders. Each category is broken down into smaller chapters that cover topics more in-depth. These video lessons make learning fun and interesting. You get to utilize self-graded quizzes and practice tests that allow you to gauge how much you have learned.

CategoryObjectives
