What happens to the chyme in the small intestine?

The chyme, or partially digested food from the stomach, is pushed along the small intestine by muscle contractions called peristaltic waves. Most of the chemical digestion and breakdown of the food happens in the duodenum. Food is mixed with bile from the gallbladder and digestive juices from the pancreas.
A.

Where is the Chyme located?

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.
  • Where is the bolus found?

    Under normal circumstances, the bolus is swallowed, and travels down the esophagus to the stomach for digestion. Once the bolus reaches the stomach, it mixes with gastric juices and becomes chyme, which then travels through the intestines for further digestion and absorption, and eventual discharge as feces.
  • What is the peristalsis?

    Peristalsis is a series of wave-like muscle contractions that moves food to different processing stations in the digestive tract. The process of peristalsis begins in the esophagus when a bolus of food is swallowed.
  • What is bile and what does it contain?

    Bile is a fluid that is made and released by the liver and stored in the gallbladder. Bile helps with digestion. It breaks down fats into fatty acids, which can be taken into the body by the digestive tract.
B.

What is the longest segment of the GI tract where most absorption takes place?

, Consist of 3 SECTIONS: DUODENUM (main place of absorbtion), JEJUNUM, and ILEUM. The longest portion of the GI tract where most digestion and absorption takes place. Fingerlike extensions of the intestinal mucosa that increase the surface area for absorption.
  • Where does the absorption of water take place in the body?

    Absorption of ingested water and most solutes occurs in the proximal small intestine, therefore the rate at which beverages are emptied from the stomach is an important factor in determining the rate of water absorption.
  • Which part of the digestive system is the longest?

    The opening at the end of the digestive tract where bowel contents leave the body. The longest part of the large intestine, which is a tube-like organ connected to the small intestine at one end and the anus at the other. The colon removes water and some nutrients and electrolytes from partially digested food.
  • Which part of the small intestine absorbs the most nutrients?

    Absorption of the majority of nutrients takes place in the jejunum, with the following notable exceptions:
    • Iron is absorbed in the duodenum.
    • Vitamin B12 and bile salts are absorbed in the terminal ileum.
    • Water and lipids are absorbed by passive diffusion throughout the small intestine.
C.

Where is Chyme converted into feces?

The large intestine consists of three major segments, the cecum (which receives chyme from the small intestine), the colon, and the rectum. As peristalsis moves chyme through the colon, water is absorbed to gradually convert the chyme into semisolid material called feces.
  • Where does the Chyme go after it leaves the stomach?

    Chyme: the name given to the partially digested food that leaves the stomach via the pyloric valve into the small intestine (duodenum). Chyme, also known as chymus has the consistency of oatmeal.
  • What happens to the chyme in the small intestine?

    The chyme, or partially digested food from the stomach, is pushed along the small intestine by muscle contractions called peristaltic waves. Most of the chemical digestion and breakdown of the food happens in the duodenum. Food is mixed with bile from the gallbladder and digestive juices from the pancreas.
  • What is the difference between the large and small intestine?

    Its job is to absorb most of the nutrients from what we eat and drink. Velvety tissue lines the small intestine, which is divided into the duodenum, jejunum, and ileum. The large intestine (colon or large bowel) is about 5 feet long and about 3 inches in diameter. The colon absorbs water from wastes, creating stool.
