Question 1 5 / 5 pts Explain why a patient with liver disease would have intolerance to fatty foods. Your Answer: One of the liver functions is to produce bile. Bile breaks down fatsand if the fat cannot not be broken down then the patient would have an issue tolerating fatty foods The liver produces bile which breaks down fats. If it is not producing bile (or less bile), fats will not be broken down effectively. Question 2 5 / 5 pts Fill in the four blanks: Food enters the stomach from the ____A_______ via the ____B______ sphincter. Food exits the stomach via the ______C______ sphincter into the____D_______. Your Answer: a. esophagus b. cardiac sphincter c. pyloric sphincter d. small intestine - Food enters the stomach from the ______A_____ : esophagus - via the _____B_____ sphincter. cardioesophageal sphincter (or lower esophageal sphincter/ LES) - Food exits the stomach via the ____C________ : pyloric - sphincter into the_____D______. small intestine (or duodenum) Question 3 8 / 10 pts Look carefully at the diagram below. Label the following 5 organs of the digestive system. To receive credit for the intestines you must label the specific region. 1: ___________ 2: ___________ 5: ___________ 6: ___________ 8: ___________ Your Answer: 1. Liver 2. pancreas 5. duodenum 6. ileum 8. large intestine 1: Liver 2: Pancreas 5: Duodenum (not small intestine) 6: Ileum (not small intestine) 8: Ascending colon (not large intestine) Question 4 5 / 5 pts A patient is experiencing vitamin toxicity.

Question 5 2.5 / 5 pts Explain which digestive system functions are carried out by the small intestine. Your Answer: the small intestine produces ezymes itself and the duodenum is where enzymes from the pancreas and bile from the liver enter the small intestine. It specializes in absorption Digestion: Chemical and mechanical: In the small intestine chemical digestion continues as enzymes from the pancreatic juices break down starches and proteins, and begin digestion of fat. Mechanical digestion continues as bile breaks down fat into smaller pieces. Absorption: begins as digested food molecules, water and fat are absorbed into the bloodstream. you didn't really discuss the idea of digestion, both chemical and mechanical Question 6 5 / 10 pts Note: Essay answers must clearly be in your own words. Answer the following essay question: Name and explain the four main functions performed by the digestive system. Your Answer: ingestion happens when the food enters your mouth digestion happens when the food breaks down inside the mouth and is mixed with saliva absorption happens when broken down food moves within the body system defecation happens when the broken down food is processed and ready to be excreted fron the rectum The digestive system has four main roles that it performs: ingestion, digestion, absorption, and defecation. Ingestion is when food enters the mouth. Digestion or food breakdown occurs when food is moved, mixed, and exposed to enzymes along the gastrointestinal tract. Digestion can be divided into two parts: mechanical and chemical digestion. Mechanical digestion occurs when food is broken down into smaller pieces. This occurs when the teeth chew food, when the stomach mixes food, and as food is moved along the gastrointestinal tract. Chemical digestion is the breakdown of food by enzymes. Absorption is the process of moving digested food into the blood stream. Defecation is the excretion of indigestible food from the anus. needed to discuss more about role of digestions, including that it takes place in other areas than the mouth; both mechanical and chemical digestion, what is happening in digestion: namely digested food is being processed in the blood stream and defecation is elimination of indigestible foods Question 7 4 / 4 pts Match the digestive organ with the one substance it produces: Correct! Pancreas Correct! Liver Correct! Mouth Other Incorrect Match Options:  Chyme  Vitamin E  Pepsinogen Question 8 3 / 3 pts What is the purpose of the hormone Leptin?
