Animal Anatomy and Physiology links


Animations are often essential for understanding the flow and interactions of physiological processes. Most animations are one to two minutes and include audio instruction.  The animation links given below can assist USA Biology Olympiad participants and instructors as they prepare for the competition.
Biology:  7th edition, Campbell and Reese
Students can have access to:  or www.campbellbiology.comif teachers will provide the access code for the book.  This site contains  animations, links, activities and primarily quizzes.  Registration is required.  The links below do not require registration.
Anatomy and Physiology Study Partner from McGraw Hill.
This site contains excellent animations for the basics of animal physiology.
The level is AP or first year undergraduate.  Supplements the Campbell disk.
The site is divided into 6 sections.  You must click on the heading and then topics to return to the main menu.
Levels of Organization
Support and Movement
Integration and Coordination
Absorption and Secretion
Reproduction and Development
The animations are highly recommended.  Most include voice over for explanation.  Recommended animations are any that are needed to help the student move from static charts to dynamic, visual perception.  A student can review the heart beating next to the graph of the cardiac cycle, inspiration and expiration showing changes in pressure in conjunction with muscle movements, urine concentration with the countercurrent mechanism, sound waves being transduced into neuronal activity in the ear and so forth. A student can review any animation that will help them integrate the physiological pathway.  
The Virtual Body offers very introductory information.
Cell Cyclin Game
Fun for the end of the day!!!!
Gastrointestinal and nutritional
McGraw Hill:  Three Phases of Gastric Secretion from chapter 43
This is hosted by the Johns Hopkins Gastroenterology and Hepatology Resource Center. To the left is the Digestive Disease Library with numerous animations.  Knowledge of diseases are NOT required for USABO, however, the animations contrasting normal with abnormal may interest may biology students.
