The small intestine is thrown into folds that increase its surface area by upto 600 times. This helps in the absorption by providing greater area for diffusion to take place through. Each villus (projection) also has a lacteal inside it, which helps in the absorption of lipids.
Bile salts aid in the absorption of fats and fat-soluble vitamins by breaking them down into smaller particles that can be more easily absorbed in the small intestine.
The pancreas produces and secretes digestive enzymes that aid in the breakdown of carbohydrates, proteins, and fats in the small intestine. Additionally, the liver produces bile, which is stored in the gallbladder and released into the small intestine to help with the digestion and absorption of fats.
Enzymatic hydrolysis of food primarily occurs in the stomach and small intestine. In the stomach, gastric enzymes help break down proteins, while in the small intestine, pancreatic enzymes aid in breaking down carbohydrates, proteins, and fats into simpler molecules for absorption.
bile is a fluid that is designed to aid with digestion.
The small intestines has a diameter of about 3 cm, and can vary greatly in length. An average adult can have a small intestine that is anywhere from 15 to 32 feet in length. The small intestine is comprised of three parts: duodenum, jejunum, and ileum.

The pancreas produces and secretes digestive enzymes that aid in the breakdown of carbohydrates, proteins, and fats in the small intestine. Additionally, the liver produces bile, which is stored in the gallbladder and released into the small intestine to help with the digestion and absorption of fats.
The small intestine contains villi and microvilli that increase its surface area for better absorption of nutrients. It also contains enzymes and bile that help in breaking down food particles for absorption. Additionally, the small intestine is lined with specialized cells that aid in nutrient absorption.
The watery liquid that moves from the stomach to the small intestine is called chyme. Chyme is a mixture of partially digested food, stomach acid, and enzymes that is produced in the stomach to aid in digestion and absorption of nutrients in the small intestine.
Enzymatic hydrolysis of food primarily occurs in the stomach and small intestine. In the stomach, gastric enzymes help break down proteins, while in the small intestine, pancreatic enzymes aid in breaking down carbohydrates, proteins, and fats into simpler molecules for absorption.
bile is a fluid that is designed to aid with digestion.
The three fluids that mix with food in the small intestine are bile from the gallbladder, pancreatic juice from the pancreas, and intestinal juice from the small intestine itself. These fluids aid in the digestion and absorption of nutrients from the food.
In herbivores, the small intestine is longer and more complex to aid in the digestion of plant material, which requires more time and surface area for absorption of nutrients. In contrast, carnivores have a shorter and simpler small intestine because the digestion of meat is more straightforward and requires less time and surface area for absorption of nutrients.

Nutrients are absorbed into the blood primarily in the small intestine. This is facilitated by the small intestine's large surface area, thanks to the presence of villi and microvilli, which aid in nutrient absorption into the bloodstream.
The gallbladder stores and releases bile, a fluid that helps break down fats in the small intestine. When you eat fatty foods, the gallbladder releases bile into the small intestine to aid in the digestion and absorption of fats.
The small intestine mucosa histology plays a crucial role in absorption of nutrients. The finger-like projections called villi increase surface area for absorption, while the microvilli on the villi aid in further increasing absorption efficiency. Goblet cells in the mucosa secrete mucus to protect the lining from mechanical damage and enzymes aid in nutrient breakdown.
