Term. PLICAE. Definition. a.are transverse folds in the mucosa and submucosa of the small intestineb.increase the surface area of the small intestinal mucosac.are mostly developed in the jejunum because more absorption occurs in the jejunum (the middle portion of the intestine). Term. F. The muscularis externa propels materials from one portion of the digestive tract to the other by a series of wavelike contractions called peristalsis, while in most areas of the small intestine __________ movements churn and fragment digestive materials. segmentation. The first section of the small intestine is the. duodenum. The human small intestine averages __________ feet in length. 20. The wall of the small intestine bears a series of folds called the. plicae circulares. The increased surface area will allow the small intestine to absorb most of the nutrients of the body. There are blood vessels and vessels contained a fluid called lymph inside the villi. Fat-soluble vitamins and fatty acids are absorbed into the lymph system. Food is moved along by peristalsis. Digestion is completed in the small intestine.   Most chemical digestion and absorption of food occurs in the small intestine. The small intestine is a long, coiled organ about one inch in diameter. The stomach connects with the duodenum, the first part of the small intestine. The function of the small intestine is to absorb nutrients through millions of vilosities along the intestine's wall, and to push food forwards by the movements of the bowels. Food is moved along by peristalsis. Digestion is completed in the small intestine.   Most chemical digestion and absorption of food occurs in the small intestine. The small intestine is a long, coiled organ about one inch in diameter. The stomach connects with the duodenum, the first part of the small intestine. The two processes that occur are digestion and absorption. Digestion is the process by which your body breaks down food into small nutrient chemicals. While absorption is the … process in which when the small nutrient molecules go through a wall of the digestive system and into the blood. The two types of movement in the small intestine are peristalsis  and segmental movements. Segmental movements, which are more common  in the small intestine than peristalsi … s, move the digesting food  back and forth in a part of the small intestine. This lets the food  mix with intestinal juices The digestive system consists of the muscular tube (called the digestive tract) and various accessory organs. The digestive tract is made up of the oral cavity (mouth), pharynx, esophagus, stomach, small intestine, and large intestine. The accessory organs are the teeth, tongue, and various glandular organs (such as the salivary glands, liver, and pancreas). The digestive functions include: 1. Histological Organization of the Digestive Tract. The major layers of the digestive tract include the mucosa, the submucosa, the muscularis externa and the serosa. The inner lining, or mucosa, of the digestive tract is an example of a mucous membrane. The three parts of the small intestine are:    duodenum-which is the first part of the small intestine where  food is being completed with chemical breakdown.  jejunu … m-which is the middle part of the small intestine -  specializes in absorbing all the nutrients (except fat) into the  body.  ileum-which is the last part where the small intestine meets  the large intestine... also where alot of bacteria sits and eats on  the undigested food.  . The two types of movement in the small intestine are peristalsis  and segmental movements. Segmental movements, which are more common  in the small intestine than peristalsi … s, move the digesting food  back and forth in a part of the small intestine. This lets the food  mix with intestinal juices The small intestine absorbs small food particles through micro villi (small finger-like tentacles that line the small intestine wall). The nutrients then go to the veins and i … s carried through the body by blood. The small intestine is also where most of the substrates bond with enzymes. Food is moved along by peristalsis. Digestion is completed in the small intestine.   Most chemical digestion and absorption of food occurs in the small intestine. The small intestine is a long, coiled organ about one inch in diameter. The stomach connects with the duodenum, the first part of the small intestine.
