Question
Identify which of the following parts of the digestive system are not parts of the digestive tract.
- Liver
- Stomach
- Mouth
- Saliva glands
- I'm not sure
Solution
The digestive tract, also known as the gastrointestinal (GI) tract, is a continuous tube that carries food from the mouth to the anus. It includes the mouth, esophagus, stomach, small intestine, and large intestine.
-
Mouth: The mouth is the beginning of the digestive tract. It is where the process of digestion begins. So, the mouth is part of the digestive tract.
-
Stomach: The stomach is a major organ in the digestive tract. It is where food is broken down by stomach acids. So, the stomach is part of the digestive tract.
-
Liver: The liver is an accessory organ of the digestive system. It produces bile, which helps in the digestion of fats. However, it is not part of the digestive tract.
-
Saliva glands: The salivary glands produce saliva, which helps in the initial breakdown of food in the mouth. However, like the liver, they are considered accessory organs and are not part of the digestive tract.
So, the liver and saliva glands are not parts of the digestive tract.
