Summary Introduction
Introduction:
The lumen of the digestive tract is on the apical or mucosal side of the intestinal epithelium. The mucosa forms the outer layer of the GI tract that faces the lumen. The epithelial cells are present in most of the tissues of the body. These cells are kept in place with the help of tight junctions, adhering junction, and desmosomes.

- Figure 34.11 Which of the following statements about the digestive system is false? Chyme is a mixture of food and digestive juices that is produced in the stomach. Food enters the large intestine before the small intestine. In the small intestine, chyme mixes with bile, which emulsifies fats. The stomach is separated from the small intestine by the pylloric sphincter.arrow_forwardWhich of the following is NOT true regarding the absorption of fat-soluble vitamins? Absorption occurs in the small intestine. Fat-soluble vitamins are incorporated into chylomicrons and transported into the lymph. A low-fat meal has no effect on fat-soluble vitamin absorption. Bile is necessary.arrow_forwardWhich of the following statements is not correct: stomach cells are protected from the acid by mucus digestive enzymes arrive into the duodenum through a duct coming from the accessory organs sphincters allow food to quickly travel through the digestive tract.. lipids are absorbed into the lymphatic capillaries known as lactealsarrow_forward
- Which of the following statements regarding digestive systems are correct? Glucose monomers are linked together by alpha 1-4 glycosidic bonds in both starch and cellulose. Gastrin is produced by exocrine cells of the gastric glands. Pepsinogen and gastric acid (HCl) are both secreted into the lumen of the stomach.arrow_forwardWhich of the following statements is TRUE? Hydrochloric acid makes an acidic environment in the stomach that promotes promotes polysaccharide digestion. Lipase, produced by the pancreas, digests the emulsified fats into fatty acids. Bile, synthesized by the liver and stored in the gall bladder, digests fats which will then be absorbed in the small intestine The acidic environment converts the inactive pepsin into its active form: pepsinogen. Pepsinogen digests proteins in the stomach.arrow_forwardWhich of the following is not true about bile?arrow_forward
- Which of the following is not true? bile is made in the liver bile is stored in the gall bladder bile helps digest fats by acting like detergents bile is released from the gall bladder into the small intestine none of thesearrow_forwardWhich one of the following features does NOT make HDL a 'good' lipoprotein. It acts as an apolipoprotein reservoir. It transfers cholesterol from VLDL and LDL into the liver. It picks up cholesterol from extra-hepatic tissues and brings it back to the liver. It acts as a cholesterol store for tissues that need cholesterol to function.arrow_forwardThe ingestion of a meal high in fat would cause which of the following to occur? bile would be released to emulsify the fat severe indigestion caused by lack of sufficient digestive enzymes the acidic secretions of the stomach would be sufficient to completely digest the foodarrow_forward
- Which of the following about bile is INCORRECT? (select multiple) o It contains enzymes for digestion It is released into the small intestines It functions to emulsify fats It is synthesized in the gall bladder It contains bilirubin and biliverdin ооarrow_forwardWhich of the following is NOT true about bile? It acrs as an emulsifier ,ie, it separates large fat droplet into small fat droplets It contains bilirubin, which is a breakdown product of hemoglobin it contains bile salts It is produced by hepatocyte in the gallbladder Its removal will not affect pepsinogen secretion.arrow_forwardThe chief cells near the base of a gastric gland secrete ________, which is converted by the acids in the gastric lumen to an active proteolytic enzyme.
