foregut

 [for´gut]
the endodermal canal of the embryo cephalic to the junction of the yolk stalk, giving rise to the pharynx, lung, esophagus, stomach, liver, and most of the small intestine.

fore·gut

(fōr'gŭt),
The cephalic portion of the primordial digestive tube in the embryo. From its endoderm arises the epithelial lining of the pharynx, trachea, lungs, esophagus, and stomach, the first part and cranial half of the second part of the duodenum, and the parenchyma of the liver, gallbladder, and pancreas.
Synonym(s): headgut

foregut

(fôr′gŭt′)
n.
1. The anterior part of the embryonic digestive tract of a vertebrate from which the pharynx, lungs, esophagus, stomach, liver, pancreas, and duodenum develop.
2. The first part of the digestive tract of an arthropod or annelid, which includes the buccal cavity, esophagus, crop, and gizzard.

foregut

[fôr′gut]
Etymology: AS, fore, in front, guttas
the cephalic portion of the embryonic alimentary canal. It consists of endodermal tissue and gives rise to the pharynx, esophagus, stomach, liver, pancreas, most of the small intestine, and respiratory ducts. Compare hindgut, midgut.

Using these cells--known as induced pluripotent stem cells, or iPS cells--the researchers were able to recreate embryonic lung development in the lab by activating a process known as gastrulation, in which the cells form distinct layers including the endoderm and then the foregut, from which the lung "grows," and then pushed these cells further to develop into distal airway tissue.
