foregut
First digestive section
The foregut is the front portion of the embryonic digestive tract, which develops into the esophagus, stomach, and upper small intestine.
In insects and other invertebrates, the foregut is the anterior section of the alimentary canal.
The term appears primarily in developmental biology and entomology.
