Overview of the Digestive System
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. In addition to the alimentary canal, there are several important accessory organs that help your body to digest food but do not have food pass through them. Accessory organs of the digestive system include the teeth, tongue, salivary glands, liver, gallbladder, and pancreas. Food begins its journey through the digestive system in the mouth, also known as the oral cavity.
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.
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.
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 digestive system -- which can be up to 30 feet in length in adults -- is usually divided into eight parts: the mouth, the esophagus, the stomach, the small intestine or "small bowel" and the large intestine also called "large bowel" or "colon" with the liver, pancreas, and gallbladder adding secretions to help digestion. These organs combine to perform six tasks: ingestion, secretion, propulsion, digestion, absorption, and defecation. The mouth starts the process by ingesting and mechanically breaking down the food we eat into a swallowable form, adding some early secretions to start the process of digestion. The esophagus is the muscular tube connecting the mouth to the stomach.

Anatomy And Physiology- The Digestive System Test
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.
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.
Which of the following organs is supported by a layer of adventitia rather than serosa? Which of the following stimuli activates sensors in the walls of digestive organs? Which of these ingredients in saliva is responsible for activating salivary amylase?
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.

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. This stage includes the mechanical breakdown of food by chewing , and the chemical breakdown by digestive enzymes, that takes place in the mouth.
Она не клюнет на твою тактику разделяй и властвуй, - сказал Стратмор, подходя еще ближе. - Отпусти. - Чатрукьян был совсем мальчишка. Ради всего святого, зачем вы это сделали.
Но завтра в восемь утра тоже есть… - Мне нужно узнать, улетела ли этим рейсом моя подруга. Она собиралась купить билет прямо перед вылетом. Женщина нахмурилась: - Извините, сэр. Этим рейсом улетели несколько пассажиров, купивших билет перед вылетом. Но мы не имеем права сообщать информацию личного характера… - Это очень важно, - настаивал Беккер.
Потеряла билет. Они не хотят и слышать о том, чтобы посадить меня в самолет. На авиалиниях работают одни бездушные бюрократы.
Клушару эта идея понравилась. Он сел в кровати. - Нуда, конечно… С удовольствием. Беккер достал блокнот. - Итак, начнем с утра.
Сьюзан застыла в полутора метрах от экрана, ошеломленная увиденным, и все называла имя человека, которого любила. ГЛАВА 115 В голове Дэвида Беккера была бесконечная пустота. Я умер. Но я слышу какие-то звуки.
