During its life cycle, Y. pestis colonizes the flea midgut and can form a biofilm in the proventricular valve in the foregut. |
Hence when the stomach develops from the foregut, as a specialized segment of the same, it is supplied by vagus branches. |
These novel morphological approaches to the study of the ommatidia and the foregut ossicles may have limited application in the fossil record. |
Then, to turn that foregut into stomach tissue, they worked out you need to add a dash of retinoic acid. |
The commencing heart, formed at this stage of two distinct tubes, is attached to the ventral side of the foregut. |
From the mouth, the esophagus leads to the foregut and then intestine, where digestion and absorption occur. |
