Answer: Stomach and Pancreas
You forgot about the liver and small intestine.
The two organs of the digestive system that are only involved in the chemical digestion of food are:
1. Pancreas
2. Stomach
To determine which two organs of the digestive system are only involved in the chemical digestion of food, we need to understand the function of each organ.
1. Mouth: The mouth is involved in both mechanical and chemical digestion. Mechanical digestion occurs through chewing and grinding food, while chemical digestion begins with the release of amylase enzymes that break down starches.
2. Esophagus: The esophagus is not directly involved in the digestion of food. It is responsible for transporting food from the mouth to the stomach.
3. Pancreas: The pancreas plays a significant role in chemical digestion. It produces digestive enzymes, such as lipase and amylase, which help breakdown fats and carbohydrates, respectively.
4. Small intestine: The small intestine is involved in both mechanical and chemical digestion. Mechanical digestion occurs through muscular contractions that mix and propel food, while chemical digestion happens through the release of various enzymes that breakdown proteins, carbohydrates, and fats.
5. Large intestine: The large intestine primarily absorbs water and electrolytes from digested food, but it does not play a significant role in chemical digestion.
6. Stomach: The stomach is involved in both mechanical and chemical digestion. Mechanical digestion occurs through muscular contractions that churn and mix food, while chemical digestion happens through the release of gastric juices, including hydrochloric acid and enzymes like pepsin, which break down proteins.
7. Liver: The liver is not directly involved in the digestion of food. However, it produces bile, which is stored in the gallbladder and then released into the small intestine to aid in the digestion and absorption of fats.
Based on the information provided, the two organs that are only involved in the chemical digestion of food are the pancreas and the stomach.
