Cells migrating inward along the [[archenteron]] form the inner layer of the [[gastrula]], which develops into the endoderm. The endoderm consists at first of flattened cells, which subsequently become columnar. It forms the epithelial lining of the whole of the [[digestive tube]] except part of the [[mouth]], [[pharynx]] and the terminal part of the [[rectum]] (which are lined by involutions of the [[ectoderm]]), the lining cells of all the glands which open into the digestive tube, including those of the [[liver]] and [[pancreas]], the [[epithelium]] of the [[auditory tube]] and [[tympanic cavity]], of the [[Vertebrate trachea|trachea]], [[bronchi]], and [[alveoli]] of the [[lungs]], of the [[urinary bladder]] and part of the [[urethra]], and that which lines the follicles of the [[thyroid gland]] and [[thymus]]. ==Production== The following graph represents the products produced by the endoderm. {| class="wikitable" !
