Whether the following statements are true or false. False statements are to be corrected.
a. The crown of a tooth is surrounded by an outer layer of pulp, which is the hardest substance in the body.
b. The filiform papillae of the tongue are keratinized, which make them rough and able to assist in mechanical digestion.
c. The three pairs of salivary glands are the parotid, submandibular, and sublingual glands.

- Explain the differences between the digestion roles of the small and large intestines. Does the appendix also have a digestive function?arrow_forwardMatch the structures to the correct descriptions. Some answers may be used more than once, and some may not be used at a Most nutrient absorption occurs here. A. submandibular This structure has 3 layers of smooth muscle rather than 2. B. pancreas Involuntary movement of this structure prevents the bolus from entering C. gall bladder the trachea. D. parotids V These are the largest salivary glands. E. large intestine V This structure receives bile and pancreatic juice. F. small intestine v During digestion, most water is absorbed here. G. liver V This structure is important in mechanical digestion. H. epiglottis V This structure produces digestive juice and enzymes that breakdown all types of maeromolecules. 1. glottis J. stomach This structure compacts the indigestible remains of digestion. V This structure produces bile. v This structure creates chyme.arrow_forwardWrite the functions of the following in the digestive process:i. Bileii. Bicarbonate secreted by the duodenal wall.iii. Pancreatic amylase.arrow_forward
- a. Give the different groups of pharmaceutical products used to treat gastrointestinal disorders. (Gastrointestinal Agents) b. Name the different kinds of ulcers and their common symptoms. (Gastrointestinal Agents) c. Define antacids and cite some criteria on what makes an ideal antacid. (Gastrointestinal Agents)arrow_forwardHistological evaluation of a portion of gastrointestinal tract shows ramified, tubular glands located in submucosal layer. The glands contain secretions with pH close to 9.0. Which of the following portions of the gastrointestinal tract is most likely inspected? A. Stomach B. Duodenum C. Jejunum D. lleum E. Ascending colonarrow_forwardThe principal function for intestinal goblet cells is: Select one: t of a. secreting digestive enzyme. b. absorbing nutrients. C. secreting one of several various hormones. d. secreting mucus.arrow_forward
- While there are numerous structural similarities among the major histological tissues of alimentary canal organs, there are also unique characteristics in specific organs. 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_forwardSelect the letter of the choice that best completes the statement. The involuntary muscle action of the alimentary canal is calleda. pushing.b. peristalsis.c. stenosis.d. contraction.arrow_forwarda person who has gingivitis can lose their teeth if the inflammation and erosion destroy which of the following? A. enamel B. pulp C. dentin D. perodontal ligamentarrow_forward
