Which of the following descriptions of the tissue layers contains inaccurate information? O A. The muscularis externa layer in the stomach is unique because it contains 3 layers of smooth muscle instead of just 2. O B. The submucosa in the esophagus is unique because it has esophageal glands that secrete a lot of mucus. OC The mucosa layer in the stomach is unique because it contains complex gastric pits with chief cells (that produce enzymes), parietal cells (that secrete acid), and enteroendocrine cells (that secrete digestive hormones). O D. All the other choices have no inaccurate information. O E. The mucosa layer in the small intestine is unique because it is responsible for the majority of chemical digestion and nutrient absorption. It has a brush border, and multiple structures to increase surface area…arrow_forward
