A long, tube-shaped organ in the abdomen that completes the process of digestion. There is both a large intestine and a small intestine. Also called the bowel.
The gastrointestinal tract; more specifically the part after the stomach, i.e. the small intestine (duodenum, jejunum, and ileum) where the greater part of digestion and absorption take place, and the large intestine.
Tubular structures at the lower end of the alimentary canal. There are two kinds of (a) Large, the terminal portion of the intestinal tract that runs in an inverted V shape from the right lower abdomen up across and down to the rectum totaling about 5 ft in length and 3 inches in breadth. The consists of the ascending colon, transverse colon, descending colon, sigmoid colon, (b) Small, that portion of the digestive tube leading from the stomach to the ascending colon, averaging about 22 ft in length and 2 inches in diameter.
The part of the digestive system between the stomach and the anus that digests and absorbs food.
That part of the alimentary canal extending from the pyloric opening of the stomach to the anus. It is divided into two major parts: the small intestine (made up of the duodenum, jejunum, and ileum), where most digestion and absorption of food occurs; and the large intestine (consisting of the cecum; appendix; ascending, transverse and descending colon; and the rectum), where water is absorbed from material passing from the small intestine. Waves of muscular contractions —peristalsis —propel material through the intestine.
The portion of the digestive system between the stomach and the anus, where absorption of nutrients into the bloodstream takes place. The intestine is in fact a long section of coiled tubing that has two parts—the small intestine and the large intestine, or colon—with different functions.
The part of the alimentary canal that extends from the stomach to the anus. It is divided into two main parts: the small intestine and the large intestine. The small intestine is divided into the duodenum, jejunum, and ileum. It is here that most of the processes of digestion and absorption of food take place. The surface area of the inside of the small intestine is increased by the presence of fingerlike projections called villi. Glands in the mucous layer of the intestine secrete digestive enzymes and mucus. The large intestine consists of the cecum, vermiform appendix, colon, and rectum. It is largely concerned with the absorption of water from the material passed from the small intestine. The contents of the intestine are propelled forward by means of rhythmic muscular contractions.
All the alimentary canal below the stomach. In it, Most digestion is carried on, and through its walls all the food material is absorbed into the blood and lymph streams. The length of the intestine in humans is about 8-5—9 metres (28—30 feet), and it takes the form of one continuous tube suspended in loops in the abdominal cavity.
The portion of the alimentary canal that extends from the pylorus of the stomach to the anus. It includes the duodenum, jejunum, ileum (small intestine), and colon (large intestine) and is responsible for the completion of digestion and the absorption of nutrients and water.
Body organ that, along with the stomach, digests food.
The long, tube-shaped organ in the abdomen that completes the process of digestion. There is both a large intestine and a small intestine. Also called the bowel. The large intestine is also called the colon.
Often referred to as the bowels, the digestive system comprises the small intestine and the large intestine. Spanning from the stomach to the anus, these organs facilitate the process of digestion and elimination.
The primary portion of the digestive tract, stretching from the lower end of the stomach to the anus. This forms an extended tube that is divided into two primary segments: the small intestine and the large intestine.
The small intestine measures around 6.5 meters in length and is composed of three segments: the duodenum, the jejunum, and the ileum. Partially digested food from the stomach is propelled through the intestine by the process of peristalsis.
The small intestine is responsible for the process of digesting and absorbing food. Digestive enzymes and bile are introduced into the partially digested food in the duodenum through the bile and pancreatic ducts. Glands within the lining of each segment of the small intestine generate mucus and additional enzymes, contributing to the breakdown of food. Nutrients are taken up by blood vessels in the intestinal walls and transported to the liver for distribution throughout the body.
The large intestine spans approximately 1.5 meters in length. Its principal part, known as the colon, is segmented into the ascending, transverse, descending, and pelvic sections (referred to as the sigmoid colon). Dangling from a pouch called the cecum, positioned between the small intestine and the colon, is the appendix. The terminal segment preceding the anus is the rectum.
Material that hasn’t been absorbed exits the small intestine in the form of liquid and fiber. During its journey through the large intestine, this material undergoes the absorption of water and mineral salts into the bloodstream. What remains are feces, composed of undigested food remnants, fats, assorted secretions, and bacteria. These feces are compacted and proceed into the rectum for eventual elimination.
The general name for that part of the digestive tract extending from the lower end of the stomach to the anus, and which, in the average adult male, is approximately 28 feet long. The first part, called the small intestine because it has a smaller diameter than the large intestine, is about 23 feet long with a diameter of about 1½ inches. It starts at the outlet of the stomach and comprises the duodenum, jejunum, and ileum, which joins with the beginning of the large intestine at the cecum. The second part, the large intestine, is about 5 feet long with a diameter of about 3 inches and comprises the cecum and appendix, ascending colon, transverse colon, descending colon, pelvic colon, and rectum. The small intestine is concerned in the digestion of food and its absorption into the body, and the large intestine with the absorption of water from the waste products of digestion and their excretion.
