These videos are provided for open education to illustrate biochemical and physiological processes of animals. Also, some of the vidoes focus on physiological processes specific to insects since I am professor emeritus of insect physiology and biochemistry in the Department of Entomology at Texas A&M University. These videos were designed as tutorials for educators and students to use for teaching and presentations. The tutorials can be obtained as downloads from my business site (link below).
