Pepsin digests proteins. What is the primary function of the large intestine?
The primary function of the large intestine is water absorption and waste excretion. What breaks up the fat in a fat-soluble vitamin in our bodies?
Bile breaks up the fat in a fat-soluble vitamin to aid in its digestion and absorption. Which of the following is not an accessory organ of digestion? a) Liver b) Pancreas c) Gallbladder d) Esophagus

c) Pancreas What are the three phases of gastric secretion?
The three phases of gastric secretion are the cephalic phase, gastric phase, and intestinal phase. Which two organs help to break food down mechanically?
The teeth and the stomach help to break food down mechanically. What is chyme?
Chyme is the partially digested food mixed with gastric juices found in the stomach and small intestine. What is the most popular meal-planning approach used by diabetics?
The carbohydrate counting method is the most popular meal-planning approach used by diabetics. Which organ(s) works with the digestive system to regulate blood sugar levels?
The pancreas works with the digestive system to regulate blood sugar levels by producing insulin and glucagon. When caring for a client with acute pancreatitis, what is the most important nursing intervention?
The most important nursing intervention is to ensure the client is NPO (nothing by mouth) to rest the pancreas. As wastes navigate the large intestine, what is primarily absorbed?
Water is primarily absorbed as wastes navigate the large intestine. How is chyme different from a bolus?
Chyme is partially digested food mixed with gastric juices in the stomach, while a bolus is chewed food mixed with saliva in the mouth and esophagus. Which large blood vessel transports nutrients from the small intestine directly to the liver?
The hepatic portal vein transports nutrients from the small intestine directly to the liver. Nutrition support is needed if burns cover what proportion of total body surface area?

c) Pancreas What is the function of the cecum?
The cecum is involved in the absorption of fluids and salts that remain after intestinal digestion and absorption. A client vomits postoperatively. What is the most important nursing intervention?
The most important nursing intervention is to ensure the client's airway is clear and to prevent aspiration. What is the estimated average intake (EAR)?
The Estimated Average Requirement (EAR) is the daily nutrient intake level estimated to meet the requirements of half the healthy individuals in a particular life stage and gender group. What statement does not pertain to the cephalic phase of gastric secretion?
The cephalic phase does not involve the direct presence of food in the stomach; it is triggered by the sight, smell, or thought of food. The teeth and tongue contribute to which function of the digestive system?
The teeth and tongue contribute to mechanical digestion by chewing and manipulating food. Which of the following best describes the role of the gut microbiome in human digestion?
