The _________ omentum attaches to the greater curvature edge of the stomach, & the __________ omentum extends between the lesser curvature of the stomach & the liver. greater; lesser Gastric folds, which are observed only when the stomach is empty, allow the stomach to __________ greatly when it fills & then returns to its normal J-shape when it empties.expand The three phases of swallowing are the _________ phase, the __________ phase, and the ________ phase. - voluntary - pharyngeal - esophageal In which part of the GI tract does mechanical digestion begin?mouth What is the function of the esophagus?nutrient absorption In the large intestine, mass movements are powerful, peristaltic like contractions involving the teniae _________ that propel fecal material toward the rectum. coli Three pairs of multicellular salivary glands are located external to the oral cavity: the _______, ________ and _______ glands. - parotid - sublingual - submandibular Most of the bone of the hard palate exhibits prominent transverse _______ folds. palatine Identify the cranial nerves associated with gastrointestinal tract motor output. Select all that apply. - facial - vagus - glossopharyngeal The roots of the teeth fit tightly into dental _________, which are sockets within the alveolar process of both the maxillae and the mandible. alveoli The _________ is the dome-shaped region lateral & superior to the esophageal connection with the stomach.fundus the _____________ is the small, narrow, superior entryway into the stomach lumen from the esophagus cardia the descending colon originates at the left _______ flexure and descends vertically until it terminates at the sigmoid colon.colic What are the five types of secretory cells from the gastric epithelium? - parietal cell - surface mucous cell - mucous neck cell - enteroendocrine cell - chief cell identify the true statements regarding lipids. - cholesterol is a type of lipid - glycerol is a component of triglycerides The accessory digestive organs produce __________ that facilitate the chemical digestive activities of GI tract organs.secretions The accessory organs of the lower GI tract include the liver, gallbladder, and ________pancreas the stratified squamous epithelial lining of the oropharynx and the laryngopharynx provides protection against the _______ activities associated with swallowing ingested materials abrasive identify the essential nutrients - lipids - water - vitamins the muscularis of the stomach is composed of three smooth muscle layers instead of two: an inner ______ layer, a middle _______ layer, and an outer ______ layer oblique; circular; longitudinal True/False: Protein digestion begins in the small intestine.FALSE [Protein digestion begins in the stomach with the enzyme pepsin.] saliva moistens ingested food and helps it become a slick, semisolid bolus that is more easily swallowed. saliva also moistens, cleanses, and lubricates the ______ cavity structures. Oral What is the function of bile?break down fats to assist in their chemical digestion at the superior end of the esophagus, the superior esophageal sphincter is a thickened ring of _______ muscle marking the area where the esophagus and the pharynx meet. G-cells of the gastric glands in the stomach produce a hormone called __________ that stimulates stomach secretions and motility. gastrin The GI tract from the esophagus through the large intestine is a tube composed of four concentric layers, called tunics. TRUE All enzymes that digest protein are released as inactive enzymes and must be activated because the enzymes would destroy the proteins within the cells that produce them. TRUE When you swallow, the soft palate and the ________ elevate to close off the posterior entrance into the nasopharynx. uvula
