• villi.
• rectum.
• bile.
• anus.
• liver.
• large intestine.
• chyme. it is a thin, watery material left when digestion in the stomach is complete.
• small intestine. it is the longest tube, through which chyme passes as it further digested and the nutrients are absorbed to be taken to the body cells.

Where does chyme pass through as it is further digested?

duodenum
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 the long tube where nutrients are absorbed?

The alimentary canal is the long tube of organs — including the esophagus, stomach, and intestines — that runs from the mouth to the anus. An adult’s digestive tract is about 30 feet (about 9 meters) long.

Which is the longest part of alimentary canal?

the small intestine
The longest part of the alimentary canal, the small intestine is about 3.05 meters (10 feet) long in a living person (but about twice as long in a cadaver due to the loss of muscle tone).

What is upper GIT?

Upper gastrointestinal tract radiography, also called an upper GI, is an x-ray examination of the esophagus, stomach and first part of the small intestine (also known as the duodenum). Images are produced using a special form of x-ray called fluoroscopy and an orally ingested contrast material such as barium.

Which is longer small intestine or large intestine?

Although the small intestine is narrower than the large intestine, it is actually the longest section of your digestive tube, measuring about 22 feet (or seven meters) on average, or three-and-a-half times the length of your body.

What is chyme Class 11?

The food gets mixed with the juice by the movements of the muscular wall of the stomach. This partially digested food with gastric juice is called chyme. Chyme is a thick and acidic semi-fluid that is transported from the stomach to the small intestine. The digestive juices are formed by the gastric glands.

What is chyme Class 10?

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.

Why is it important that chyme from the stomach is delivered to the small intestine slowly and in small amounts?

This distinguishes the small intestine from the stomach; that is, enzymatic digestion occurs not only in the lumen, but also on the luminal surfaces of the mucosal cells. For optimal chemical digestion, chyme must be delivered from the stomach slowly and in small amounts.

What is the longest part of the large intestine?

The transverse colon is the third, most mobile, and longest part of the large intestine.

Which is the longest part of the alimentary canal which is fitted into a compact space because of extensive coiling?

Small intestine
Small intestine is the longest part of the alimentary canal which is fitted into a compact space because of extensive coiling.

What happens to chyme as it passes through the stomach?

In both the small and the large intestine, water is normally absorbed so the chyme gradually gets thicker. As chyme passes through the stomach and intestine, it picks up cellular debris and other types of waste products.

Where is absorption most abundant in the small intestine?

These adaptations are most abundant in the proximal two-thirds of the small intestine, where the majority of absorption occurs. Figure 23.6.2 – Histology of the Small Intestine: (a) The absorptive surface of the small intestine is vastly enlarged by the presence of circular folds, villi, and microvilli.

How much mucus is secreted from the small intestine per day?

Each day, about 0.95 to 1.9 liters (1 to 2 quarts) are secreted in response to the distention of the small intestine or the irritating effects of chyme on the intestinal mucosa.
