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. Stomach contents enter the esophagus Causes Heartburn Condition called GERD (gastro-esophageal reflux disease).omiting 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.

Next, the tongue pushes the food from the mouth to the throat (pharynx). The voice box (larynx) closes so no food can enter the breathing passages or lungs. Finally, a special muscle called a sphincter, located where the throat and esophagus join, opens so the food can move into the esophagus. Esophageal phase of swallowing. The esophagus is a tube-like organ that connects the mouth and throat with the stomach. At each end, the tube is closed by the contraction of special muscles called sphincters. The esophagus and sphincter muscles are designed to move what is swallowed to the stomach. They also prevent stomach contents from moving back up into the esophagus and breathing passages. Food that enters the esophagus is squeezed down to the stomach by a special muscle contraction called peristalsis.
