The human digestive system, also known as the digestive tract, the GI tract, the alimentary canal is a series of connected organs leading from the mouth to the anus. The digestive system allows us to break down the food we eat to obtain energy and nourishment.

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion the tongue , salivary glands , pancreas , liver , and gallbladder. Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. The process of digestion has three stages: the cephalic phase , the gastric phase , and the intestinal phase. The first stage, the cephalic phase of digestion, begins with gastric secretions in response to the sight and smell of food.

Digestive System

This presentation was prepared using draft rules. Other than the intestines and the stomach, the following are also part of the digestive system: The role the teeth play in food processing needs little introduction; we masticate, or chew, by opening and closing our jaws and moving them from side to side while continuously using our tongue to move the food between our teeth. B: Parietal cells produce HCl. Answer the question s below to see how well you understand the topics covered in the previous section. All of these are functions of the tongue. It begins in the stomach, where some small, lipid-soluble molecules, such as alcohol and aspirin, can diffuse through the stomach epithelium into the circulation.

Human digestive system , system used in the human body for the process of digestion. The human digestive system consists primarily of the digestive tract , or the series of structures and organs through which food and liquids pass during their processing into forms absorbable into the bloodstream. The system also consists of the structures through which wastes pass in the process of elimination and other organs that contribute juices necessary for the digestive process. The digestive tract begins at the lips and ends at the anus. It consists of the mouth , or oral cavity, with its teeth , for grinding the food, and its tongue , which serves to knead food and mix it with saliva ; the throat, or pharynx ; the esophagus ; the stomach ; the small intestine , consisting of the duodenum , the jejunum, and the ileum ; and the large intestine , consisting of the cecum , a closed-end sac connecting with the ileum, the ascending colon, the transverse colon, the descending colon, and the sigmoid colon , which terminates in the rectum. Glands contributing digestive juices include the salivary glands , the gastric glands in the stomach lining, the pancreas , and the liver and its adjuncts—the gallbladder and bile ducts. All of these organs and glands contribute to the physical and chemical breaking down of ingested food and to the eventual elimination of nondigestible wastes.

Digestive System Anatomy and Physiology

The function of the digestive system is to break down the foods you eat, release their nutrients, and absorb those nutrients into the body. Although the small intestine is the workhorse of the system, where the majority of digestion occurs, and where most of the released nutrients are absorbed into the blood or lymph, each of the digestive system organs makes a vital contribution to this process [link]. As is the case with all body systems, the digestive system does not work in isolation; it functions cooperatively with the other systems of the body. Consider for example, the interrelationship between the digestive and cardiovascular systems. Arteries supply the digestive organs with oxygen and processed nutrients, and veins drain the digestive tract.

Overview of the Digestive System

NCBI Bookshelf. The digestive system comprises the gastrointestinal tract and accessory organs. The gastrointestinal tract consists of the oral cavity, pharynx, esophagus, stomach, small intestine, and large intestine. The accessory organs are the teeth, tongue, and the glandular organs such as salivary gland, liver, gallbladder, and pancreas.

The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract GI tract. The alimentary canal is made up of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines.

As adults, we know that a healthy digestive system is essential for good health because it converts food into raw materials that build and fuel our body cells. The organs of the digestive system can be separated into two main groups: those forming the alimentary canal and the accessory digestive organs. The alimentary canal, also called the gastrointestinal tract, is a continuous, hollow muscular tube that winds through the ventral body cavity and is open at both ends. Its organs include the following:. Food enters the digestive tract through the mouth , or oral cavity, a mucous membrane-lined cavity. The esophagus or gullet , runs from the pharynx through the diaphragm to the stomach. The role the teeth play in food processing needs little introduction; we masticate, or chew, by opening and closing our jaws and moving them from side to side while continuously using our tongue to move the food between our teeth.

Introduction

 - Вы ждете рекомендаций. Что ж, пожалуйста. Хватит путаться у нас под ногами, вот моя рекомендация. - Спокойно, Джабба, - предупредил директор. - Директор, - сказал Джабба, - Энсей Танкадо владеет нашим банком данных. Дайте ему то, чего он требует.

Anatomy And Physiology- The Digestive System Test

 Может быть, все это чепуха, - сказала Мидж, - но в статистических данных по шифровалке вдруг вылезло что-то несуразное. Я надеюсь, что ты мне все объяснишь. - В чем же проблема? - Джабба сделал глоток своей жгучей приправы. - Передо мной лежит отчет, из которого следует, что ТРАНСТЕКСТ бьется над каким-то файлом уже восемнадцать часов и до сих пор не вскрыл шифр.

Сьюзан это показалось разумным. Цифровая крепость впервые запустила функцию переменного открытого текста; быть может, ТРАНСТЕКСТ сумеет взломать шифр за двадцать четыре часа. Но честно говоря, она в это уже почти не верила. - Пусть ТРАНСТЕКСТ работает, - принял решение Стратмор.  - Я хочу быть абсолютно уверен, что это абсолютно стойкий шифр.
