What is a Chyme quizlet?

chyme. a semiliquid mass of partially digested food that passes from the stomach through the pyloric sphincter into the duodenum.

What prevents chyme from exiting the stomach?

The pyloric sphincter serves as a kind of gateway between the stomach and the small intestine. It allows the contents of the stomach to pass into the small intestine. It also prevents partially digested food and digestive juices from reentering the stomach.

What is the function of the Chyme?

There are two major functions of chyme – the first is to increase the surface area of food to allow digestive enzymes to complete their work, and the second is to stimulate various digestive glands to release their secretions.

What does the Chyme pass through?

Chyme results from the mechanical and chemical breakdown of a bolus and consists of partially digested food, water, hydrochloric acid, and various digestive enzymes. Chyme slowly passes through the pyloric sphincter and into the duodenum, where the extraction of nutrients begins.

What is called chyme?

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 chyme in the digestive system quizlet?

Forms chyme: the semi-liquid blend of food and gastric secretions that forms in the stomach during digestion. Controls movement of chyme into the small intestine at a rate suitable for digestion and absorption by the small intestine.

How is chyme neutralized?

In order to neutralize the acidic chyme, a hormone called secretin stimulates the pancreas to produce alkaline bicarbonate solution and deliver it to the duodenum. Secretin acts in tandem with another hormone called cholecystokinin (CCK).

Why is neutralization of chyme important?

chyme, a thick semifluid mass of partially digested food and digestive secretions that is formed in the stomach and intestine during digestion. This fluid neutralizes the highly acidic gastric juice, which would otherwise damage the membrane lining of the intestine, resulting in a duodenal ulcer. …

Why does chyme need to be neutralized?

What is chyme composed of quizlet?

Chyme: the name given to the partially digested food that leaves the stomach via the pyloric valve into the small intestine (duodenum).

What happens to the chyme in the small intestine?

During this time, a stomach enzyme called pepsin breaks down most of the protein in the food. Next, the chyme is slowly transported from the pylorus (end portion of the stomach) through a sphincter and into the small intestine where further digestion and nutrient absorption occurs.
