Question
Chapter 25.2, Problem 8BYGO
Summary Introduction
Introduction:
Swallowing in other words deglutition is a difficult activity involving about 22 muscles in the pharynx, mouth, and esophagus that are synchronized by the swallowing center, a nuclei pair in the medulla oblongata. The swallowing center communicates with pharynx muscles and esophagus muscles by the way of cranial nerves.

A- Even if there isnt chyme in the duodenum, stomahc acid might leak into the duodenum. the trypsin in pancreatic juice neutralizes that B- We eat a lot, so we're always digesting food in the duodenum C - the process of fat breakdown is slow, so lipids could stay in the duodenum for over a day, so we need a steady supply of pancreatic lipase.

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).
