Answers and explanations

  1. Question: Which organ grinds food into tiny pieces with teeth?
    Answer: Mouth
    Explanation: The mouth starts digestion by chewing and mixing food with saliva to make swallowing easy. People sometimes say 'stomach' but chewing happens in the mouth.
  2. Question: What tube carries food from the throat to the stomach?
    Answer: Esophagus
    Explanation: The esophagus is a stretchy tube that pushes food down with muscle waves called peristalsis. It's not the windpipe (trachea), which carries air.
  3. Question: Which organ stores and churns food with acids and enzymes?
    Answer: Stomach
    Explanation: The stomach mixes food and breaks it down with acid and enzymes so nutrients can be freed later. It isn't where most nutrients are absorbed—that happens in the small intestine.
  4. Question: Where are most nutrients absorbed into the body?
    Answer: Small intestine
    Explanation: The small intestine has tiny finger-like villi that soak up nutrients into the blood. Despite its name, it's very long and the main place for absorption.
  5. Question: Which organ removes waste water and makes stool firmer?
    Answer: Large intestine
    Explanation: The large intestine soaks up water and forms stool before it leaves the body. Kids often mix it up with the small intestine, but the large one handles water and waste.
  6. Question: Which organ makes bile to help break down fats?
    Answer: Liver
    Explanation: The liver makes bile, which helps fat digestion and is stored in the gallbladder. The gallbladder stores bile but doesn't make it, which is a common mix-up.
  7. Question: Which tiny helper makes juices to digest food in the small intestine?
    Answer: Pancreas
    Explanation: The pancreas sends digestive juices and insulin to help process food and sugar; it works with the small intestine. People sometimes think it's only for sugar, but it aids digestion too.
