- 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_forwardFigure 34.19 Which of the following statements about digestive processes is true?

- Food comes into contact with several anatomical structures as it passes through the body. Which of the following is INCORRECT with respect to the approximate order of passage of food through the gut? Question 16 options: oropharynx > epiglottis > jejunum > ileocecal valve > anal sphincter esophagus > duodenum > ilium > ascending colon > anal sphincter oral cavity > cardiac sphincter > pyloric sphincter > ileocecal valve > anus epiglottis > stomach > jejunum > sigmoid colon > anus lips > cardiac sphincter > pyloric valve > ileocecal valve > anusarrow_forwardThe patient has a delayed outflow of bile from the gallbladder. What may this condition lead to? Emulsification would be correct. Chylomicrons wouldn't be able to function normally. Micelles would be formed correctly. Bile salts wouldn't be formed from cholesterol. Bile salts wouldn't be able to function normally.arrow_forwardWhere does final digestion of food and absorption of nutrients occur in the gastrointestinal tract?
