Ingestion, which occurs in the mouth, is the first step of the digestive process. After food enters the mouth, the teeth chew it. Saliva, which is produced by the salivary glands, plays a major role in breaking down the food into smaller pieces. These small pieces travel to the stomach through the esophagus.
That PETA has an impossible agenda and that someone probably tried to make money by making my film look bad, does not excuse the mistakes made 65 months ago, irrespective of the fact that the dog in question was unharmed.
Although unnecessary exposure to radiation should be avoided, the low levels of radiation one is exposed to during an x ray does not cause harm with a few exceptions. Pregnant women should not have x rays unless in emergencies the benefits highly outweigh the risks. Exposure of the fetus to x rays, especially during early pregnancy can increase the risk of the child later developing leukemia. Body parts not being x rayed should be shielded with a lead apron, especially the testes, ovaries, and thyroid.

Little aftercare is needed following an x ray. In complicated x rays where contrast material is injected into a blood vessel, the individual may need to remain under medical care for a short while to assure that there is no allergic reaction to the contrast material and recovery is complete.
Fluoroscopy is a special x-ray technique that produces real-time images on a television monitor. With fluoroscopy, contrast material is injected into a blood vessel. The physician can then watch the real-time movement of the contrast material to determine if there are blockages in circulation. Fluoroscopy is also used to help guide catheters into place in the heart during cardiac catheterization or to guide an endoscope during endoscopic surgery.
American antifoundationalist Richard Rorty makes a similar point: "Nothing grounds our practices, nothing legitimizes them, nothing shows them to be in touch with the way things are" ("From Logic to Language to Play," 6986). This epistemological cul-de-sac, Rorty concludes, leads inevitably to nihilism. "Faced with the nonhuman, the nonlinguistic, we no longer have the ability to overcome contingency and pain by appropriation and transformation, but only the ability to recognize contingency and pain" ( Contingency, Irony, and Solidarity, 6989 ). In contrast to Nietzsche's fears and the angst of the existentialists, nihilism becomes for the antifoundationalists just another aspect of our contemporary milieu, one best endured with sang-froid.
Endoscope x7569 A medical instrument that can be passed into an area of the body (the bladder or intestine, for example) to allow visual examination of that area. The endoscope usually has a fiberoptic camera that allows a greatly magnified image to be shown on a television screen viewed by the operator. Many endoscopes also allow the operator to retrieve a small sample (biopsy) of the area being examined, to more closely view the tissue under a microscope.
