Which of the following is an accessory organ that does not come into direct contact with food? A) Small intestine B) Liver C) Stomach D) Esophagus
Answer (1)
In the context of the human digestive system, accessory organs are those that aid in the digestion process but do not have physical contact with the food. These organs provide essential functions like the production of enzymes, hormones, and other substances that help break down food.
Let's examine each option:
A) Small Intestine - This is not an accessory organ. It's part of the digestive tract where nutrient absorption occurs, and it comes into direct contact with the food.
B) Liver - This organ is an accessory organ of digestion. It produces bile, which helps in the digestion of fats, but it doesn't directly contact the food. Instead, it releases bile into the small intestine through the bile duct.
C) Stomach - This is a primary organ of the digestive system where digestion begins. It comes into direct contact with food, as it uses stomach acids and enzymes to break down the food.
D) Esophagus - This is part of the digestive tract that carries food from the mouth to the stomach. It directly contacts food as it facilitates its movement.
Given that the liver is involved in the digestion process without directly contacting food, it is the correct choice.
Correct answer: B) Liver
