B) Mesoderm forms most of the glands of the GIT
C) The buccopharyngeal membrane ruptures at the end of the 3rd week of development to open the GIT to the amniotic cavity.
D) During transverse folding of the embryo, the lateral parts of the intraembryonic coelom are brought together on the ventral aspect of the embryo. in the region of the future peritoneal cavity the ventral mesentry degenerates resulting in a large embryonic peritoneal cavity extending from below the heart to the pelvic region.
E) The foregut is supplied by the celiac artery.
