• Esophagus. Once you begin swallowing, the process becomes automatic.
• Lower esophageal sphincter.
• Stomach.
• Small intestine.
• Large intestine.
• Rectum.

Additionally, what are the four stages of food processing and describe what happens in each stage?

How does your stomach work?

The stomach is a muscular hollow organ. It takes in food from the esophagus (gullet or food pipe), mixes it, breaks it down, and then passes it on to the small intestine in small portions. When you swallow, these muscles relax and the lower end of the esophagus opens, allowing food to enter the stomach.

What are the 2 types of digestion?

There are two kinds of digestion: mechanical and chemical. Mechanical digestion involves physically breaking the food into smaller pieces. Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells.

How does the body digest fat?

What organ of the digestive system does trypsin work?

Trypsin is an enzyme that helps us digest protein. In the small intestine, trypsin breaks down proteins, continuing the process of digestion that began in the stomach. It may also be referred to as a proteolytic enzyme, or proteinase. Trypsin is produced by the pancreas in an inactive form called trypsinogen.

What cells make up the digestive system?

Where is Chyme stored?

The partially digested food and gastric juice mixture is called chyme. Chyme passes from the stomach to the small intestine. Further protein digestion takes place in the small intestine.

How is Chyme produced?

Chyme, a thick semifluid mass of partially digested food and digestive secretions that is formed in the stomach and intestine during digestion. In the stomach, digestive juices are formed by the gastric glands; these secretions include the enzyme pepsin, which breaks down proteins, and hydrochloric acid.

What is the main purpose of the digestive system?

The digestive system is divided into two major parts: The digestive tract (alimentary canal) is a continuous tube with two openings: the mouth and the anus.

What happens during ingestion?

Ingestion – the taking in of food Food is taken into the mouth where it is physically broken down by the teeth into smaller pieces. The presence of food in the mouth triggers a nervous reflex that causes the salivary glands to deliver a watery fluid called saliva to the mouth.

What is the final step in food processing?

Elimination. The final step in digestion is the elimination of undigested food content and waste products. The undigested food material enters the colon, where most of the water is reabsorbed. Recall that the colon is also home to the microflora called “intestinal flora” that aid in the digestion process.
