Bile salts aid in the digestion of fats in the small intestine by emulsifying large fat globules into smaller droplets. Produced by the liver and stored in the gallbladder, bile salts are released into the duodenum in response to the presence of fatty chyme. Bile salts have hydrophobic and hydrophilic regions, allowing them to surround fat droplets and break them into smaller particles. This increased surface area facilitates the action of lipases, enzymes that hydrolyze triglycerides into fatty acids and monoglycerides. Emulsification by bile salts enhances the efficiency of fat digestion and the subsequent absorption of fatty acids in the small intestine.
Pancreatic juice contains several enzymes crucial for digestion. Amylase breaks down complex carbohydrates (starches) into simpler sugars like maltose. Lipase hydrolyzes triglycerides into fatty acids and glycerol, facilitating fat digestion. Proteases, such as trypsin and chymotrypsin, break down pRead more
Pancreatic juice contains several enzymes crucial for digestion. Amylase breaks down complex carbohydrates (starches) into simpler sugars like maltose. Lipase hydrolyzes triglycerides into fatty acids and glycerol, facilitating fat digestion. Proteases, such as trypsin and chymotrypsin, break down proteins into peptides and amino acids. These enzymes are released into the duodenum in response to chyme, contributing to the digestive process initiated in the stomach. The actions of pancreatic enzymes, combined with bile from the liver, ensure the efficient breakdown of macronutrients in the small intestine, promoting nutrient absorption for energy and metabolic functions.
Intestinal juice in the small intestine plays a vital role in digestion and absorption. It contains enzymes like peptidases, which further break down peptides into amino acids, completing protein digestion.

Intestinal juice in the small intestine plays a vital role in digestion and absorption. It contains enzymes like peptidases, which further break down peptides into amino acids, completing protein digestion. Additionally, intestinal juice contains maltase, sucrase, and lactase, enzymes that hydrolyze disaccharides into simple sugars (glucose, fructose, and galactose). These enzymes aid in the digestion of carbohydrates. Intestinal juice also contributes mucus, providing lubrication and protection to the intestinal lining. Together with pancreatic and bile secretions, intestinal juice facilitates the final stages of digestion and maximizes nutrient absorption in the small intestine, ensuring the extraction of essential components for energy and growth.
Absorbed nutrients are transported throughout the body via the bloodstream and the lymphatic system. Water-soluble nutrients, like amino acids and sugars, enter the bloodstream through capillaries in the villi of the small intestine. They are then carried to the liver via the hepatic portal vein befRead more
Absorbed nutrients are transported throughout the body via the bloodstream and the lymphatic system. Water-soluble nutrients, like amino acids and sugars, enter the bloodstream through capillaries in the villi of the small intestine. They are then carried to the liver via the hepatic portal vein before entering the general circulation. Fat-soluble nutrients, including fatty acids, are absorbed into the lymphatic system through lacteals within the villi. The lymphatic vessels transport these nutrients, forming chylomicrons, which enter the bloodstream at the thoracic duct. This dual transport system ensures the distribution of absorbed nutrients to various tissues and organs for energy production and metabolic functions.

Unabsorbed food in the digestive process, including indigestible fibers and certain waste materials, proceeds to the large intestine. In the large intestine, water absorption and microbial fermentation occur. The gut microbiota break down remaining complex carbohydrates and produce gases and short-chain fatty acids. Water is absorbed, transforming the material into a semisolid form known as feces. The formed feces are stored in the rectum until eliminated through the anus during defecation. This final stage of digestion and waste elimination ensures the extraction of water and residual nutrients while expelling indigestible components, completing the digestive process.
