About this worksheet

Digestion and getting rid of waste. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

  • I can name the organs food passes through, in order, and say what each one does.
  • I can tell the food tube from its helpers (liver, pancreas, gallbladder), which send juices in through ducts.
  • I can match each waste to its exit: carbon dioxide to the lungs, urine to the kidneys, food leftovers to the large intestine.

Standard: MS-LS1-3

Words to know

esophagus: The muscle tube from the mouth to the stomach

small intestine: Where digestion finishes and most nutrients pass into the blood

large intestine: Takes in water from leftovers; the waste then leaves the body

bile: A juice from the liver that helps digest fats

duct: A small tube that carries a juice into the intestine

villi: Tiny finger-like bumps that add surface to the small intestine

kidney: Organ that filters blood and makes urine from wastes and extra water

ureter / bladder: Tube from each kidney / the pouch that stores urine

Common mistakes

Your child thought food passes through the liver, pancreas or gallbladder. They are helpers beside the food tube: their juices flow in through small tubes called ducts.

Your child mixed up the two intestines. The small intestine comes first and absorbs most nutrients; the large intestine comes last and takes in water from what is left.

Your child thought the stomach finishes digestion and absorbs the food. The stomach starts breaking food down; the small intestine finishes the job and absorbs most nutrients.
