The three main phases of digestion are the cephalic phase (triggered by sight, smell, etc.), gastric phase (in the stomach), and intestinal phase (in the small intestine). The other options either mention incorrect body parts (oral, esophageal, rectal, buccal, pharyngeal), or processes not representing main phases (excretion, secretion, mastication, churning).
