Digestive System Quizzes & Trivia

Questions and Answers
  • 1. 

    Your salivary glands are a mixture of secretions that help break down food.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Salivary glands are responsible for producing saliva, which contains enzymes that aid in the digestion of food. These enzymes help in breaking down complex molecules into simpler forms, making it easier for the body to absorb nutrients. Therefore, the statement that salivary glands are a mixture of secretions that help break down food is true.

  • 2. 

    Your esophagus is not synchronized to move food down to the stomach.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because the esophagus is indeed synchronized to move food down to the stomach. The esophagus uses a series of muscular contractions called peristalsis to push food from the throat to the stomach. This coordinated movement ensures that food is transported efficiently and effectively through the digestive system.

  • 3. 

    The pancreas makes enzymes that help break down proteins, carbohydrates and fats.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The pancreas is an important organ in the digestive system that produces enzymes. These enzymes play a crucial role in breaking down proteins, carbohydrates, and fats in the digestive process. Therefore, the statement that the pancreas makes enzymes that help break down proteins, carbohydrates, and fats is true.

    Rate this question:

  • 4. 

    The stomach has mucus that replaces itself every two weeks because of the harsh acid in the stomach.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The stomach lining is protected by a layer of mucus that helps to prevent the harsh stomach acid from damaging the stomach tissue. This mucus layer is constantly being replaced every two weeks to ensure its effectiveness in providing this protection. Therefore, the statement is true.

    Rate this question:

  • 5. 

    The Digestive System begins in the nose.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement that the Digestive System begins in the nose is false. The digestive system actually begins in the mouth, where the process of digestion starts with chewing and the release of saliva. From the mouth, food travels down the esophagus and into the stomach, where further digestion takes place. Therefore, the nose is not part of the digestive system.

    Rate this question:

  • 6. 

    What are the organs that work together to break down food called?

    • A.

      The lymphatic system

    • B.

      The digestive system

    • C.

      The alimentary system

    • D.

      The intestinal system

    Correct Answer
    B. The digestive system
    Explanation
    The correct answer is the digestive system. The digestive system is a group of organs that work together to break down food into smaller molecules that can be absorbed by the body. This system includes organs such as the mouth, esophagus, stomach, small intestine, and large intestine. These organs perform various functions like chewing, swallowing, digesting, and absorbing nutrients from food. The lymphatic system, alimentary system, and intestinal system are not correct as they do not specifically refer to the organs involved in breaking down food.

    Rate this question:

  • 7. 

    How does chewing help digestion?

    • A.

      Chewing makes food taste better.

    • B.

      Chewing makes food last longer.

    • C.

      Chewing makes food smaller.

    • D.

      Chewing makes it harder for bacteria to grow

    Correct Answer
    C. Chewing makes food smaller.
    Explanation
    Chewing helps digestion by making food smaller. When we chew our food, it breaks down into smaller pieces, which increases the surface area of the food particles. This allows digestive enzymes in our saliva and stomach to easily break down the food into smaller molecules, making it easier for our body to absorb and digest nutrients. Chewing also stimulates the production of saliva, which contains enzymes that start the digestion process. Additionally, chewing thoroughly can help prevent digestive issues like bloating and indigestion.

    Rate this question:

  • 8. 

    What has an enzyme that starts digesting carbohydrates as you chew?

    • A.

      Incisors

    • B.

      Saliva

    • C.

      Gums

    • D.

      Esophagus

    Correct Answer
    B. Saliva
    Explanation
    Saliva contains an enzyme called amylase, which is responsible for starting the digestion of carbohydrates. When you chew food, the saliva mixes with it and the amylase in saliva begins breaking down the complex carbohydrates into simpler sugars. This process is the first step in the digestion of carbohydrates and helps prepare the food for further digestion in the stomach and intestines.

    Rate this question:

  • 9. 

    Why is the small intestine called "small"?

    • A.

      It is short.

    • B.

      It is small in diameter/

    • C.

      It doesn't hold much.

    • D.

      It doesn't weigh much.

    Correct Answer
    B. It is small in diameter/
    Explanation
    The small intestine is called "small" because it has a relatively small diameter compared to other parts of the digestive system. This allows for efficient absorption of nutrients as the smaller diameter allows for a larger surface area for absorption.

    Rate this question:

  • 10. 

    What do the villi in the small intestine do?

    • A.

      Kill bacteria

    • B.

      Protect the small intestine

    • C.

      Absorb nutrients

    • D.

      It is small in diameter

    Correct Answer
    C. Absorb nutrients
    Explanation
    The villi in the small intestine are finger-like projections that increase the surface area for absorption of nutrients. They contain specialized cells that have microvilli on their surface, which further increase the surface area. This allows for efficient absorption of nutrients from digested food into the bloodstream. The villi play a crucial role in the digestive process by maximizing nutrient absorption and ensuring that the body receives the necessary nutrients for proper functioning.
