Which organs are included in the Digestive System?

• B. Nose, pharynx, larynx, trachea, bronchi, lungs
• C. Mouth, pharynx, esophagus, stomach, intestines, liver, gallbladder, pancreas
• D. Ovaries, fallopian tubes, uterus, vagina, mammary glands

Answer: (C)

Digestive system organs are those that break down food, absorb nutrients, and eliminate waste, including the main digestive tract and the glands that assist digestion. The group shown includes the mouth, pharynx, esophagus, stomach, and intestines—the path food travels where mechanical and chemical digestion and nutrient absorption occur. It also lists the liver, gallbladder, and pancreas, which are accessory digestive organs: the liver makes bile to digest fats, the gallbladder stores bile, and the pancreas releases digestive enzymes into the small intestine. This combination reflects the full set of components that work together to digest food and manage nutrients.

The other options correspond to different body systems: one includes organs of the urinary system, another the respiratory system, and another the reproductive system.
