Overview of the User Interface Development Process. This section outlines the three phases of user interface design and introduces the tasks that are typically associated with each phase. The Application User Interface and the User Experience. To begin, the terms user interface and user experience must be clarified.
The enterogastric reflex is one of the three extrinsic reflexes of the gastrointestinal tract, the other two being the gastrocolic reflex and the gastroileal reflex. The enterogastric reflex is stimulated in the duodenum by a pH of 3-4 and in the stomach by a pH of 1.5.Upon initiation of the reflex, the release of gastrin by G-cells in the antrum of the stomach is shut off.This in turn inhibits gastric motility and the secretion of gastric acid (HCl).he enterogastric reflex is stimulated in the duodenum by a pH of 3-4 and in the stomach by a pH of 1.5.

Nasogastric (NG) intubation is a procedure during which a thin, plastic tube is inserted through the nostril, down the esophagus, and into the stomach. Once an NG tube is in place, healthcare providers can deliver food and medicine directly to the stomach or remove substances from it. Nasogastric (NG) intubation is most often used to deliver food and medicine to a patient when they are unable to eat or swallow. Patients most likely to need an NG tube include: 1  comatose patients. 2  patients with neck or facial injuries, or recent surgeries. 3  patients breathing with the assistance of a mechanical ventilator.
