The gastrointestinal tract GIT consists of a hollow muscular tube starting from the oral cavity, where food enters the mouth, continuing through the pharynx, oesophagus, stomach and intestines to the rectum and anus, where food is expelled. There are various accessory organs that assist the tract by secreting enzymes to help break down food into its component nutrients. Thus the salivary glands, liver, pancreas and gall bladder have important functions in the digestive system. Food is propelled along the length of the GIT by peristaltic movements of the muscular walls. Information on re-publishing of our images.

Please consult the latest official manual style if you have any questions regarding the format accuracy. Understand the basic functions of the gastrointestinal system and the design features that subserve these Describe the functional layers of the gastrointestinal tract and the specializations that contribute to function Glands Epithelium Mucosa Muscle Sphincters Identify the segments of the gastrointestinal tract and the specialized functions attributed to each Understand the circulatory features of the intestine and variations that occur after meals Describe the basic anatomy of the neuromuscular systems of the gut. The gastrointestinal system primarily conveys nutrients, electrolytes, and water into the body. In unicellular organisms, metabolic requirements can be met by diffusion or transport of substances from the environment across the cell membrane. However, the greatly increased scale of multicellular organisms, along with the fact that most such organisms are terrestrial, and thus not normally swimming in a soup of nutrients, means that specialized systems have evolved to convey nutrients into and around the body. Thus, the gastrointestinal system and liver work in concert with the circulatory system to ensure that the nutritional requirements of cells distant from the exterior of the body can be met.

The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body. The digestive system is divided into two major parts:. The treatment of food in the digestive system involves the following seven processes:. Propulsion is the movement of food along the digestive tract.

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 stomach is a muscular, J-shaped organ in the upper part of the abdomen. It is part of the digestive system, which extends from the mouth to the anus.

Gastrointestinal system anatomy

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.

The stomach is a muscular, J-shaped organ in the upper part of the abdomen. It is part of the digestive system, which extends from the mouth to the anus. The size of the stomach varies from person to person, and from meal to meal.

Digestion and Absorption

Так продолжалось несколько недель. За десертом в ночных ресторанах он задавал ей бесконечные вопросы. Где она изучала математику. Как она попала в АНБ. Как ей удалось стать столь привлекательной. Покраснев, Сьюзан сказала, что созрела довольно поздно. Чуть ли не до двадцати лет она была худой и нескладной и носила скобки на зубах, так что тетя Клара однажды сказала, что Господь Бог наградил ее умом в утешение за невзрачные внешние данные.

Даже если Цифровая крепость станет общедоступной, большинство пользователей из соображений удобства будут продолжать пользоваться старыми программами. Зачем им переходить на Цифровую крепость. Стратмор улыбнулся: - Это. Мы организуем утечку секретной информации. И весь мир сразу же узнает о ТРАНСТЕКСТЕ.

Пуля ударилась о мрамор совсем рядом, и в следующее мгновение он уже летел вниз по гранитным ступеням к узкому проходу, выходя из которого священнослужители поднимались на алтарь как бы по милости Божьей. У подножия ступенек Беккер споткнулся и, потеряв равновесие, неуправляемо заскользил по отполированному камню. Острая боль пронзила вес его тело, когда он приземлился на бок, но мгновение спустя он уже был на ногах и, скрываемый занавешенным входом, сбежал вниз по деревянным ступенькам. Превозмогая боль, он бежал через гардеробную. У алтаря кто-то кричал, за спиной у него слышались тяжелые шаги. Беккер толкнул двойную дверь и оказался в некотором подобии кабинета. Там было темно, но он разглядел дорогие восточные ковры и полированное красное дерево.

Беккер остановился, недоумевая, откуда им известно его имя. - Кто… кто вы .

Если Цифровой крепости суждено стать любимой игрушкой АНБ, Стратмор хотел убедиться, что взломать ее невозможно. - Ты по-прежнему хочешь уйти. Сьюзан посмотрела на .

Он ослабил узел галстука и рухнул на стул у ближайшего свободного столика. Казалось, что с той минуты, когда рано утром ему позвонил Стратмор, прошла целая вечность. Сдвинув в сторону пустые пивные бутылки, Беккер устало опустил голову на руки.
