Digestion Facts: How Well You Know? Quiz - Quiz


How well do you know about digestion? Do you think you can assimilate this quiz? Digestion is the breakdown of large insoluble food molecules into small soluble food molecules to be absorbed. In basic terms, digestion is how your body turns the food you eat into nutrients and uses it or energy. Taking this quiz will help you grasp facts about digestion.


Questions and Answers
  • 1. 

    The fatty acids and glycerol are then absorbed into the blood stream via the villi of the_________

    Correct Answer
    small intestine
    Explanation
    The fatty acids and glycerol are absorbed into the bloodstream via the villi of the small intestine. The small intestine is responsible for the majority of nutrient absorption in the body. The villi are small finger-like projections that line the inner surface of the small intestine and increase its surface area, allowing for efficient absorption of nutrients. As the fatty acids and glycerol pass through the small intestine, they are taken up by the villi and transported into the bloodstream to be used for energy or stored for later use.

    A high fiber diet will reduce damage to the?

    • A.

      Stomach

    • B.

      Heart

    • C.

      Colon

    Correct Answer
    C. Colon
    Explanation
    A high fiber diet will reduce damage to the colon because fiber adds bulk to the stool and helps it move through the digestive system more easily. This reduces the time that waste spends in the colon, decreasing the risk of constipation, hemorrhoids, and diverticulosis. Additionally, fiber helps to maintain a healthy balance of bacteria in the colon, which is important for overall digestive health.

    A low fibre diet along with dehydration and low activity levels, can lead to____________ disease.

    Correct Answer
    diverticular, diverticular disease
    Explanation
    A low fibre diet, dehydration, and low activity levels can contribute to the development of diverticular disease. Diverticular disease refers to the formation of small pouches (diverticula) in the lining of the colon. When there is a lack of dietary fibre, the stool becomes harder and more difficult to pass, leading to increased pressure in the colon. Dehydration can further exacerbate this by causing the stool to become even harder. Low activity levels can also contribute to constipation and decreased bowel movements, increasing the risk of diverticular disease.

    Dehydration occurs when we lose

    • A.

      1% fluid

    • B.

      3% fluid

    • C.

      2% fluid

    Correct Answer
    C. 2% fluid
    Explanation
    Dehydration occurs when we lose 2% fluid because our body needs a certain amount of water to function properly. When we lose more than 2% of our body's fluid, it can lead to symptoms such as thirst, dry mouth, fatigue, and dizziness. It is important to stay hydrated by drinking enough water throughout the day to prevent dehydration and maintain optimal health.

    Mastication occurs in the_________

    Correct Answer
    mouth
    Explanation
    Mastication refers to the process of chewing food, which is primarily done in the mouth. The mouth contains teeth and the tongue, which work together to break down food into smaller pieces, making it easier to swallow and digest. Therefore, it is logical to conclude that mastication occurs in the mouth.

    One function of the esophagus is?

    • A.

      Responsible for a large percentage of digestion

    • B.

      Delivering food to the stomach

    • C.

      Absorb water from the remains of food

    Correct Answer
    B. Delivering food to the stomach
    Explanation
    The esophagus is responsible for delivering food to the stomach. It is a muscular tube that connects the throat to the stomach, allowing food to pass through and enter the digestive system. Once food is chewed and swallowed, it travels down the esophagus through a series of muscular contractions called peristalsis, which pushes the food towards the stomach. Therefore, the esophagus plays a crucial role in the process of delivering food from the mouth to the stomach for further digestion.

  • 7. 

    Pepsin is produced to break down protein in which section of the digestive system?

    • A.

      Stomach

    • B.

      Large intestine

    • C.

      Small intestine

    Correct Answer
    A. Stomach
    Explanation
    Pepsin is an enzyme that is produced in the stomach. Its main function is to break down proteins into smaller peptides, which can then be further digested in the small intestine. The stomach is the first major site of protein digestion in the digestive system, where pepsin is secreted by the gastric glands. Therefore, the correct answer is the stomach.
