Diagnostic Imaging is a Key Tool in the Early Diagnosis and Prevention of Disease. Of high importance in today's managed care environment, diagnostic imaging can also be used for the early identification of potential medical problems, to help prevent their occurrence. Thus expensive therapeutic treatment may be eliminated to create substantial savings for the patient and healthcare system.
Vomiting is a vital reflex controlled by the medulla oblongata LES relaxes-allowing stomach contents to move into the esophagus Diaphragm and abdominal muscles contract-squeezing the stomach & forcing contents upwards. î î î. Esophagus enters the abdominal cavity through an opening in the diaphragm.This opening becomes enlarged, stomach is pushed up into the thoracic cavity. Additional pressure causes the LES to relax.

Anatomically and functionally, the esophagus is the least complex section of the digestive tube. Its role in digestion is simple: to convey boluses of food from the pharynx to the stomach.The esophagus begins as an extension of the pharynx in the back of the oral cavity.bsorption in the esophagus is virtually nil. The mucosa does contain mucous glands that are expressed as foodstuffs distend the esophagus, allowing mucus to be secreted and aid in lubrication. The body of the esophagus is bounded by physiologic sphincters known as the upper and lower esophageal sphincters.
