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.

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

Even though we are constantly breathing, we do not often think about what is happening when we do so. This narrated animation describes respiration of the lungs and oxygenation of the blood.

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.

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.

The lungs are comprised of thousands of alveoli or air sacs. These structures are only one or two cells thick at places but they are able to separate blood and inhaled air. Oxygen and carbon dioxide are exchanged across this thin membrane, as the narrated animation explains.

Dental implants are artificial teeth that are anchored to bone; however if the bone is too thin, the dental implant cannot be implanted. The animation describes the bone grafting procedure that is sometimes necessary to build up the bone show that it can support a dental implant.

The human ear requires a number of highly specialized anatomical structures in order to transform sound wave energy into actually sounds recognized by the brain. This animation shows the various structures of the outer, middle and inner ear and how they work together to detect sound.

Periodontal disease is disease which occurs in the gums around the teeth. Left untreated, disease of this area can lead to pain and tooth loss among other problems. One way to treat periodontal disease is through laser treatment of the gums. The narrated animation shows how concentrated light energy (lasers) can be used to treat these diseases.

A physician explains some of the most common sleep disorders like insomnia, narcolepsy, and restless legs syndrome. The video begins by explaining the process of sleep and what occurs in the brain as we sleep. Video and graphic animations are used as teaching tools throughout.

In this video, a physician describes both Type 1 and Type 2 Diabetes Mellitus and the problems that can occur when diabetes is not properly controlled.

This narrated 3D animation shows how the brain drives the specialized nerve cells of the pituitary gland and, in turn, how the pituitary gland effects other endocrine glands. The feedback regulation of the endocrine system is also described.

It is not uncommon for fluid to accumulate behind the eardrum (tympanic membrane). In this animation, we see the surgery used to open the tympanic membrane (myringotomy) and the placement of a drainage tube. This procedure is known colloquially as a patient "getting tubes in his ears."
