Ingluvies - This word was used in the second round of the 2012 national spelling bee. It is the crop, or widened part of the esophagus in many mollusks, insects, and birds, which accumulates, stores, and sometimes begins chemically processing food. In flies, butterflies, and other insects that use liquid food, the ingluvies is a sac mounted on a stalk. In bees the fermentative processing of flower nectar into honey takes place in the ingluvies. The expanded portions of the esophagus in annelid worms, nematodes, and nemerteans are also called ingluvies (paraphrased from a free, open source, online dictionary).
