Question

Describe the small intestine. Explain the process of digestion in the small intestine.​

Answer 1

Answer:

The small intestine (small bowel) is about 20 feet long and about an inch in diameter. Its job is to absorb most of the nutrients from what we eat and drink. Velvety tissue lines the small intestine, which is divided into the duodenum, jejunum, and ileum

The small intestine is where most chemical digestion takes place. Most of the digestive enzymes in the small intestine are secreted by the pancreas and enter the small intestine via the pancreatic duct. ... The three major classes of nutrients that undergo digestion are proteins, lipids (fats), and carbohydrates.
