Using graphic animation, this video shows the step by step process for removing tonsils and adenoids, including these anatomical structures that are located in the throat.

This animation not only shows how the ear detects sound waves and converts those waves into nerve signals, but it also shows how cochlear implants work and allow patients with nerve deafness to hear.

This 3D animation describes why we need to respire oxygen and why that requirement is increased during exercise.

Mostly everyone has heard of tonsillectomy, that is, a surgery to remove the tonsils; but the location of the tonsils is often no more clear than "somewhere in the throat." This narrated animation shows where the tonsils are located and gives an approximation of what they look like when they are inflamed and headed for tonsillectomy.
