Please match each description with the correct structure. Fingerlike extensions of the intestinal mucosa that increase the surface area for absorption. Large collections of lymphoid tissue found in the submucosa of the small intestine. Deep folds of the mucosa and submucosa that extend completely or partially around the circumference of the. Mobile organ that manipulates food in the mouth and initiates swallowing. Conduit (tube) for both air and food. Part of the digestive system superior to the stomach that has no absorptive, mechanical processing, or chemical. Folds of the gastric mucosa. Small bulges along the length of the large intestine.

The digestive system is the organ system that processes food, extracts nutrients, and eliminates the residue. Its function is accomplished in five stages. a. __________________________ b. __________________________ c. _________________________ d. __________________________ e. _________________________ The digestive phase has two facets, ______________________ and _________________________. a. The first one is achieved by the processes of __________________ and ______________________. b. ________________________ exposes food surface to the action of digestive enzymes. The digestive system has two anatomical subdivisions, the digestive tract and the accessory organs. 1. The digestive tract (alimentary canal) is a muscular tube extending from mouth to anus. 2. The accessory organs are _______________, ________________, ____________________. 3. Most of the digestive tract follows a basic structural plan, with a wall composed of the following tissue layers, in order from inner to outer surface: a. __________________________ b. _________________________ c. _________________________ d. _________________________ The esophagus, stomach, and intestines have a nervous network called the ____________________________. a. This system regulates digestive tract motility, secretion, and blood flow. b. It is composed of two networks of neurons: _______________ (Meissner) plexus, and the ____________________(Auerbach) plexus of parasympathetic ganglia and nerve fibers between the layers of the muscularis externa. The stomach and intestines must be free to move in the abdominal cavity and are not tightly bound to the abdominal wall, but are suspended from it by the ______________________. Two anterior mesenteries called omenta are associated with the stomach. a. The _____________________ extends from the right superior margin (lesser curvature) of the stomach to the liver. b. The ____________________ hangs from the left inferior margin (greater curvature) of the stomach and loosely covers the small intestine like an apron. The esophagus is a straight muscular tube. 1. It begins at a level between vertebra C6 and the cricoid cartilage, inferior to the larynx and posterior to the trachea. 2. After passing downward through the mediastinum, the esophagus penetrates the diaphragm at the _________________________ and continues another 3 to 4 cm to meet the stomach at the level of T7. 3. The opening into the stomach is called the ________________ (because of its proximity to the heart) or ____________________ 4. Swallowing occurs in three phases. a. The _______________ is under voluntary control. i. The tongue collects food, presses it against the palate to form a bolus, and pushes it posteriorly. b. The _____________________ is involuntary. i. The soft palate and root of the tongue prevent food and drink from reentering the mouth or entering the nasal cavity. c. The ___________________ is a wave of involuntary contractions called peristalsis, controlled by the swallowing centers and the myenteric plexus in the esophageal wall.
