The intestinal phase triggers the release of mucus and bicarbonate to help protect the duodenum from arriving acid. The cephalic phase begins before food enters the stomach and includes sensory input from the sight, smell, and taste of food. The gastric phase can last for hours, not just minutes. The release of bile from the gallbladder is not part of the cephalic phase or the gastric phase. The intestinal phase inhibits the stimulation of the stomach's stretch receptors, rather than increasing it.
