Final answer:
The mucosal layer does not form the peritoneum. The false statement about the GI tract wall is that the mucosal layer forms the peritoneum; the mucosa is actually the innermost layer and the peritoneum is associated with the serosa. The esophagus has an adventitia instead of a serous membrane.
Step-by-step explanation:
The false statement about layers of the wall of the GI tract is b. The mucosal layer forms the peritoneum.
The mucosal layer is the innermost layer surrounding the lumen of the GI tract and consists mainly of the epithelium with the capacity to secrete and absorb substances. The peritoneum, on the other hand, is a serous membrane that lines the abdominal cavity and covers some of the organs in the GI tract. It is not formed by the mucosal layer.
The false statement about the GI tract wall is that the mucosal layer forms the peritoneum; the mucosa is actually the innermost layer and the peritoneum is associated with the serosa. The esophagus has an adventitia instead of a serous membrane.
The false statement about layers of the wall of the GI tract is: The mucosal layer forms the peritoneum. The correct information is that the mucosa is the innermost layer that surrounds the lumen of the GI tract. The peritoneum is not formed by the mucosal layer; rather, it is associated with the serosa, which is the outermost layer of the GI tract organs in those parts where it is present. The esophagus, for example, is covered by an adventitia rather than a serous membrane.
The submucosa contains large blood and lymph vessels that transport absorbed nutrients. The muscularis layer, or muscularis externa, is responsible for movements such as segmentation and peristalsis. Each layer of the GI tract wall has a specific structure and function that adapt to the various functions of different parts of the GI tract.
