The accessory organs of the gastrointestinal (GI) tract are the organs that aid in the digestion and absorption of food but are not directly involved in the passage of food through the GI tract
The accessory organs of the gastrointestinal (GI) tract are the organs that aid in the digestion and absorption of food but are not directly involved in the passage of food through the GI tract.
Based on the given options, the following are accessory organs of the GI tract:
1. Pancreas: The pancreas plays a crucial role in digestion by producing digestive enzymes, such as amylase, lipase, and proteases, which break down carbohydrates, fats, and proteins, respectively. It also produces bicarbonate, which helps neutralize stomach acid in the small intestine.
2. Gallbladder: The gallbladder stores and concentrates bile, which is produced by the liver. Bile is released into the small intestine to aid in the digestion and absorption of fats by emulsifying them into smaller droplets, increasing their surface area for digestion by pancreatic lipase.
The small intestine, however, is not an accessory organ, but rather a primary organ of the GI tract. It is responsible for the majority of digestion and absorption of nutrients.
The esophagus is also not an accessory organ. It is a muscular tube that functions primarily to transport food from the mouth to the stomach through peristaltic contractions.
