The objective of this website is to offer high-quality, inexpensive animations to educators and students for teaching physiology and biochemistry. 

Physiological and biochemical processes are the basis for life.  These processes occur in space and time and frequently involve a series of complicated events.  For these reasons, students often have difficulty conceptualizing how these complex processes occur.

Unlike books where diagrams are stationary and changes are indicated with arrows, animated computer models can dynamically demonstrate the sequence of events for physiological and biochemical processes.

Computer animations represent a significant, new, inexpensive tool to help students visualize and learn physiology and biochemistry.  Therefore, I have developed these animations based upon 37 years of experience in university teaching and research in the areas of comparative physiology and biochemistry. It is my goal to help my colleagues teach, and students to learn and understand, these complex and fascinating processes.

The name "PhysioViva" is derived from physiology and viva — Latin for “animated” or “lively”. The goal of the animations is to bring PHYSIOLOGY to LIFE for students.  The logo is based on insect instars (larva, pupa and adult).  It uses the insect physiologist's favorite “white rat”, the tobacco hornworm, as its example.  In the logo, each instar resides within its distinctive subsequent instar as a symbolic depiction of metamorphosis — the dramatic physiological transitions of insect growth and development.

“The animations are an excellent tool to summarize and integrate the knowledge acquired in each unit.  If a picture is worth a thousand words, these animations are worth a million.  I cannot imagine now teaching Insect Physiology without them. The students truly "get it"after watching them.  Dr. Keeley did a wonderful job for all of us teaching physiology, toxicology and molecular insect science.” - Dr. Patricia Pietrantonio, Professor of Insect Physiology, Texas A&M University

“As an undergraduate, I was an extremely visual learner.  Certain concepts are simply not easily explained using words alone.  Without these animations to explain physiological processes to me, I would have been completely in the dark.  Now as a graduate student, the material is more in depth and complicated.  These animations continue to help me visualize these complex processes.  They are also fantastic tools which allow teachers to cater to different learning styles.  I highly recommend them to all physiology teachers, regardless of grade level.”  -  S.M.B., undergraduate/graduate student, Department of Entomology, Texas A&M University

“I am an undergraduate student at UC Davis majoring in entomology.  In addition to textbooks and lectures, your animations are a wonderful tool for anyone.  I am a visual learner, and being able to see  "movement" is extremely helpful for me. The design, color and presentation of the animations, make the concepts very clear and easy to understand.  Thank you very much.” - A.C.L.

“I am not a teacher but a postgraduate seeking for such illustrative information such as your animations. They are really great and helpful. Thanks!” - S.B., University clinic Vuk Vrhovac, Dugi dol 4a, Zagreb, CROATIA
