    d) Dairy products
  • Which organ is not an accessory organ of the digestive system?
    Esophagus
  • How does the muscular system interact with the digestive system?
    The muscular system aids in the movement of food through the digestive tract via peristalsis and segmentation.
  • What sphincter separates the small intestine from the large intestine?
    The ileocecal sphincter separates the small intestine from the large intestine.
  • Which of these enzymes is not produced in the pancreas? a) Amylase b) Lipase c) Pepsin d) Trypsin
    c) Pepsin
  • Which muscles help us in the initial breakdown of food?
    The muscles of the jaw and tongue help in the initial breakdown of food through chewing.
  • Which information is most significant when assessing a client suspected of having a peptic ulcer?
    The most significant information is the presence of Helicobacter pylori infection or the use of NSAIDs.
  • How do the nutrients from food get to the body's cells?
    Nutrients from food are absorbed into the bloodstream in the small intestine and transported to the body's cells.
  • Why is “fingerlike” a good description for the villi in the small intestine?
    “Fingerlike” describes the villi because they are small, finger-shaped projections that increase the surface area for absorption.
  • What is responsible for the emulsification of lipids in the duodenum?
    Bile is responsible for the emulsification of lipids in the duodenum.
  • What is a digestive function of the liver?
    Producing bile
  • What is chyme?
    Chyme is the partially digested food mixed with gastric juices found in the stomach and small intestine.
  • What role do bacteria in the large intestine play?
    Bacteria in the large intestine help in the fermentation of undigested carbohydrates and the production of certain vitamins.
  • In which organ does almost all enzymatic digestion of food occur?
    Almost all enzymatic digestion of food occurs in the small intestine.
  • Which of these structures contain digestive enzymes? a) Salivary glands b) Liver c) Gallbladder d) Esophagus
    a) Salivary glands
  • Which accessory organ is responsible for storing sugar in the form of glycogen?
    Liver
  • What is pepsin's role when digesting protein?
    Pepsin breaks down proteins into smaller peptides in the stomach.
  • What is true regarding the digestive system in mammals?
    Mammals have a complete digestive system with a mouth, esophagus, stomach, intestines, and accessory organs.
  • In which organ does protein digestion begin?
    Protein digestion begins in the stomach.
  • Which body system converts food into simpler substances for the body to absorb as nutrients?
    The digestive system converts food into simpler substances for the body to absorb as nutrients.
  • How does the muscular system support the digestive system?
    The muscular system supports the digestive system by facilitating the movement of food through peristalsis and segmentation.
  • Where does the process of segmentation occur?
    The process of segmentation occurs in the small intestine.
  • Which substance inhibits the secretion of the gastric glands?
    Secretin
  • Which organ is responsible for creating digestive enzymes?
    Pancreas
  • What structures are used by both the respiratory and digestive systems?
    The pharynx is used by both the respiratory and digestive systems.
  • What occurs during the gastric phase of gastric secretion?
    During the gastric phase, the presence of food in the stomach stimulates the secretion of gastric juices.
  • Which organ is not an accessory digestive organ?
    Esophagus
  • Which pancreatic enzyme is responsible for the breakdown of carbohydrates?
    Amylase is the pancreatic enzyme responsible for the breakdown of carbohydrates.
  • What structure prevents food and liquids from entering the trachea?
    The epiglottis prevents food and liquids from entering the trachea.
  • How does the digestive system support the muscular system?
    The digestive system provides nutrients absorbed from food that are essential for muscle function and repair.
  • What might stimulate the cephalic phase of gastric secretion?
    Smelling food
  • What is the cephalic phase?
    The cephalic phase is the initial phase of gastric secretion triggered by the sight, smell, or thought of food.
