How is food carried on through the alimentary canal? Simple.\n\nThrough the process of peristalsis. Peristalsis is crudely defined as the waves of involuntary muscle contractions that transport food, waste matter, or other contents through a tube-shaped organ such as the intestine.\n\nMicrosoft® Encarta® Reference Library 2004. © 1993-2003 Microsoft Corporation.

The gastrointestinal tract or digestive tract, also referred to as the GI tract or the alimentary canal or the gut, is the system of organs within multicellular animals which takes in food, digests it to extract energy and nutrients, and expels the remaining waste.\n\nThe GI tract differs substantially from animal to animal. For instance, some animals have multi-chambered stomachs.

Peristalsis is a method or a occurence that happens when the food goes down the digestive tract. the frequent  relaxation and contraction of the muscles in the digestive tract allow the food to go from the mouth to your stomach\n\nChyme is the food that is partially digested and it is transferred from stomach to the duodenum (the entrance of small intestine)\n\nVilli is something hair-like structure that is present in your small intestine. The major function of villi is to absorb nutrients\n\nIt ususally takes an two and half to six hours for food to be done in the digestive system.\n\nThe function of the large intestine is to absorb water, vitamin and electrolytes\n\nYou mean the digestive tract? about 9 meters.. or 30 feet

Digestion is merely the series of physical and chemical changes that food undergoes within the body in preparation for nutrients to be absorbed. Physical changes such as chewing and swallowing, and chemical changes that involve the digestive juices (enzymes) cause the breakdown of foods. The three main types of energy-yielding nutrients dependent upon digestion are carbohydrates, protein and fats.\n\nAbsorption is the process by which nutrients are taken up by the intestines and passed into the bloodstream to be delivered to all cells in the body. Absorption of nutrients takes place mainly in the small intestine, where its surface area is comparable to a quarter of a football field and its length is 20 feet! The intestine fits into your stomach with hundreds of folds. Its surface is covered with billions of small "finger" like projections called villi. These villi are in constant motion and covered in microscopic "hair" like strands that trap the now tiny nutrients and help them move into the villi cells. \n\nMetabolism is the process of all the chemical changes that nutrients undergo from the time they are absorbed until they become part of the body or are excreted. Metabolism is the conversion of digested nutrients into the components for energy or building materials.

its a buil up of gases inside your stomach trying to escape... for example when you drink a can of soft drink its the gasses escaping from the fluid that builds in your stomach which then force themselves through your throat.

Gastric colic reflex: \nAn increase in the muscle contractions within the date GI tract when food enters the empty stomach. This reflex causes many patients to have a bowel movement after eating.

Think of whales. They have that siv-like stuff that strains krill and plankton stuff out of the water, to be swallowed and digested later.\n\nOk, now for a smarter explination: \n\nWhen humans eat, there's a lot more methods and reasons behind digestion than simply mechanical breakdown.\nFood starts in the mouth, where salivary amylaze, an enyzme, begins to break down starch. The mechanical process increases the surface area of the food, allowing a more rapid breakdown. Peristalsis moves food along the digestive track, partially digesting and absorbing along the way. In the stomach, chemicals from the gallbladder and pancreas are secreted to further breakdown food (with stomach fluid, "acid chyme"), and specifically protein (by enzyme "pepsin," thus the antacid medicine). This is known as "chemical digestion." Stomach muscles also aid in mixing digestive enzymes; this is what happens when your stomach lurches, bubbles (but gas can cause this also), "talks," or churns. Next, as food travels to the small and then large intestine, fat in food is absorbed in the small and water in the large.\n\nSpecies vary in the ammount of breakdown needed for their body to absorb nutrients. This describes the function of most. On the whole, animals besides humans use teeth to intimidate predators and capture prey. Some snakes swallow eggs whole, and would use teeth only to defend against the mother bird. The venus fly-trap captures flies and then disables them without teeth. Spiders don't have teeth, persay, but poisonous fangs which disable their prey--you may recall that they merely "suck" the liquids out of their food. \nAnimals equipped with other mechanisms besides teeth to capture prey have no need for them to digest.

The digestion begins in the mouth. The teeth chew & grind the food, so they perform physical digestion. Next, the saliva contains ptyalin, which helps to digest starch into maltose sugar. the food then moves down the oesophagus.\n\nIn the stomach, the gastric juices are secreted, which contain Hydrochloric acid, pepsin (enzyme), gastric lipase and mucus. Pepsin digests proteins into peptones. Gastric lipase breaks down fat molecules. The partially digested food then goes into the duodenum. Here, bile and pancreatic juice are secreted. The pancreatic juice contains trypsin and pancreatic amylase. The bile emulsifies the fat. The trypsin digests proteins, while the emylase digests breaks down the starch. Finally, the walls of the ileum secrete succus entericus, which completes the digestion of carbohydrates into glucose, proteins into amino acids and fats into fatty acids.

GI (Gastrointestinal) system.  It's where digestion begins with ezymes that break down food (salivary amylase, also known as pytalin) and mucous that coats the food and takes it down the esophagous.\nCheck the literature.  They are used interchangeably.

Well the food is broken down by stomach acid (HCl). I'm not a biologist, but I believe all food undergoes the same general reaction.

Mouth, esophagus, stomach, small intestine, large intestine, colon, rectum, anus are the parts the food or the waste from food travel through.  Side line contributors are glands such as\nsaliva glands, liver, gall bladder, pancreas.

This food is entered into the body via the mouth, where enzymes such as lysozyme begin to breakdown the food while it is chewed. When this food is broken down into smaller pieces it can then be swallowed, where it travels down the oesophagus towards the stomach.\n\nThe stomach then continues to break down the foodstuff. The stomach at this point is filled with a type of acid that further breaks down the food, until it is in the duodenum, which is part of the small intestine. It is here where the food is completely broken down, in the following manner:\n\n    * Proteins are broken down into amino acids\n    * Fats into fatty acids\n    * Complex sugars into simple sugars\n\nFrom here, you can see that a complex product (the food you eat) is stripped bare, until the substances that they are broken down to can be used by the body in some way. By breaking down these foodstuffs to their most basic nature, the body can then rebuild these substances as and when required, for example, to create enzymes.\n\nThe Physiological Homeostasis page in the Regulation of Biological Systems tutorial looks at how the body determines when a particular action is required, such as the increase of blood sugar concentration. Also, the Cell Biology Tutorial page ADP and ATP introduces ATP, the body's biological energy, and how it is created, which is continued on the following page.\n\nLink below tells the rest of the story.

im studying the digestive system right now, so i'll have a go at this question (u may want to chec accuracy).\nthe cell gets the carbon it needs via the blood supply. when we eat, all the nutrients are broken down and molecules such as hydrogen, oxygen and carbon are filtered into the blood stream so that they can be passed on to all the cells in th body.\n\ndoes that help?

Do you mean reabsorption of water?\n\nFor human, reabsorption of water occurs at the large intestine where processed leftovers its water and moisture that hadn't been fully absorbed and digested is bein' extracted.

" Chronic intestinal pseudo-obstruction (CIP) is a rare disorder of gastrointestinal motility where coordinated contractions (peristalsis) in the intestinal tract become altered and inefficient. When this happens, nutritional requirements cannot be adequately met.\n\n"Motility" is the term used to describe the contraction of muscles in the gastrointestinal (GI) tract. To facilitate normal digestion and the absorption of nutrients, food content is propelled through the GI tract by synchronized or coordinated contractions in a process called "peristalsis." Peristalsis is dependent upon the coordination between the muscles, nerves, and hormones in the digestive tract.\n\nIn CIP the intestines react as if there is a true mechanical obstruction or blockage. However, when tests are performed, no physical evidence of blockage is found. There is no unique sign or symptom that allows a positive diagnosis of the pseudo-obstruction. "\n\nthere is more information in that link, too.

The solids that come out as feces come out of the end of the alimentary canal, which is one long tube from your mouth to your butt, so poop is basically everything you ate but couldn't digest.  Urine is a filtrate of the blood and is not directly connected to the intestines.  It is where much of the waste that the cells produce and dump into the blood is filtered and excreted, instead of just being left overs from meals like feces is.
