Which organ physically and chemically breaks down food?
The pancreas and gland cells of the small intestine secrete digestive enzymes that chemically break down complex food molecules into simpler ones.
What organ is chemically and mechanically digested food?
Proper digestion requires both mechanical and chemical digestion and occurs in the oral cavity, stomach, and small intestine. Additionally, digestion requires the secretions from accessory digestive organs such as the pancreas, liver, and gallbladder.
How is Chyme converted to feces?
In the large intestine, bacteria break down any proteins and starches in chyme that were not digested fully in the small intestine. When all of the nutrients have been absorbed from chyme, the remaining waste material changes into semisolids that are called feces.
How long does it take to convert chyme to feces?
Chyme slowly passes through the pyloric sphincter and into the duodenum, where the extraction of nutrients begins. Depending on the quantity and contents of the meal, the stomach will digest the food into chyme in some time from 40 minutes to 3 hours….

Where do most digestive products enter the bloodstream?
The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream.
What organ helps break up food?
The stomach performs four main functions: mechanical digestion by contracting to smash up food, chemical digestion by releasing acid to help chemically break up food, and then absorption and secretion. The stomach is sometimes surgically removed as a result of cancer or trauma.
Which organ breaks down food and absorbs nutrients?
In the stomach, enzymes break down food such as carbohydrates, protein and fats, so that nutrients can be absorbed farther down the GI tract , according to the National Digestive Disease Information Clearinghouse. The stomach mixes and churns foods to slowly release into the small intestine.
What organs does food not pass through?
As they are accessory organs of the digestive system, the gallbladder and pancreas have no food passing through them. They do, however, act as storage organs by storing the chemicals necessary for the chemical digestion of foods.
What is organ chemically breaks down food?
The digestive glands (salivary glands, pancreas, liver, and gallbladder) produce or store secretions that the body carries to the digestive tract in ducts and breaks down chemically. Food processing begins with ingestion (eating). The teeth aid in mechanical digestion by masticating (chewing) food.
