Digestive System is the category for questions regarding the breakdown and absorption of food-stuffs in our alimentary canal. Questions about the stomach and intestines can be included in this category.

A food chute has no digestive or absorptive role?
The esophagus.
gullet=food chute. it does not digest things or absorb nutrients and goodies and stuff
What organs are part of the digestion system?
mouth-chew in the food the saliva get it moist it turns to a ball
Why are digestive enzymes are called hydrolases?
Any enzyme that uses hydrolysis (break a molecule in two, break H2O into OH- and H+, match one ion with one piece of molecule, result in two smaller molecules) is called a hydrolase. In chemical digestion, hydrolysis is the main chemical reaction used by the enzymes to break proteins, lipids, carbohydrates, and other complex molecules into smaller pieces.
Why are the three parts of the large intestine called ascending transverse descending?
It has to do with the direction the waste travels in. Ascending is the section of bowel (large intestine) where waste travels up the intestine, transverse is the section that goes across the middle of your body and descending is the part that flows down toward the colon ready for excretion through the rectum and anus.
it is secreted by stomach glands as an inactive proenzyme, pepsinogen, which is converted to pepsin by the cleavage of acid-labile linkages in the acidic (low pH) environment of the stomach.
the pepsin would become innactive
Where does Bile it act in the digestive system?
The bile from the bile duct is sent to the pancrease and is then secreted unto the food, or at this point chime, in the doudenum.
Why does stomach acid come back up in mouth?
First a little anatomy lesson;
There is a muscle at the bottom of the esophagus (the tube between the mouth and the stomach), called the 'lower esophageal sphincter' (LES), that tightens to close the opening to the stomach after a person stops eating and/or drinking to prevent the backing up (reflux) of stomach content into the esophagus.
So the reason why stomach acid, or any liquid/food, comes back up from the stomach and into the mouth (also called regurgitation) is because this muscle has not done what it was supposed to do at that time. It either became loose, or didn't close all the way.
Causes that loosen this muscle can be many - from taking certain medications (pain pills, muscle relaxers, etc.), eating certain foods and drinks (chocolate, peppermint, citrus fruits/drinks, alcohol, soda, coffee, etc.) to the position of the body (bending over a certain way), or anything that causes extra pressure on the stomach, even certain medical conditions.
If it only happens once or twice, I agree, it's not too much to worry about. Just drink some water to push/wash the acid back down into the stomach, because you don't want the acid to stay in the esophagus or back of throat because it can cause damage to teeth and the esophagus itself.
If it happens more often, a trip to a doctor, in order to find out or rule out any medical condition, such as GERD, Acid Reflux, hernia, or any other contributing factor.

You probably ate fried or greasy food. When fried or greasy food is consumed, your body must create more acid to break it down. When the food is gone, the acid remains. Your body slowly gets rid of the excess acid, but slowly. The acid is so hot, that it slowly rises, like a hot air balloon. Then, your mouth! Don't worry, it should do it once or twice, then go away.
Is there a food the digestive system cant digest?
Cellulose, in general, is not digested. But it serves an important function in diet anyway as "insoluble fiber". You get cellulose fiber from foods like lettuce and other greens, asparagus -- pretty much any fibrous veggie.
An illness or allergy can prevent some people from digesting certain foods, but this is specific to the person and not typical of human beings generally.
Lactose intolerance (milk sugar) is common in adults, and is actually genetically NORMAL. The ability of adults to digest milk sugar is a genetic mutation that is typical of populations in areas where milk was an essential staple in the diet, such as the far north of Europe and other places where agriculture is difficult because of climate.
How digestion takes place through carbohydrates?
That would be chemical digestion, because carbohydrates are molecules, therefore they are also chemicals.
What is the mutualistic relationship between animals and digestive bacteria?
The animals need the bacteria to help break down the food. The bacteria benefit since they get food, while we benefit since the bacteria help us digest our food.
What effect does boiling have on enzyme digestion?
Many proteins coagulate at temperatures above 70°C (A boiled egg is an obvious example).
Does rice give you bad digestion?
I am actually having problems digesting a large quantity of rice. So I suspect is hard for some people to break it. It has a huge amount of calories and carbohydrates and maybe it is not so light after all.
What neutralize the gastric juices?
alkaline juices is the duodenum secreted from glands in the gut wall.
Why does a shark take so long to digest food?
It takes about 24 hours for a crocodile to digest any animal, including humans. This is because crocodiles don't chew their food, they basically swallow most of it whole. They have strong stomachs that break down the food very well.
Where organ is important in processing substances after they are absorbed during digestion?
The Liver.
as it enters the mouth it is broken down by mechenical digestion. then with the aid of the tounge it is pushed down into the oesophagus to the sttomach where it is furthur broken down chemiclly and mixeed with hydrochloric acid. it then leaves as a semi liquid substance into the small intestine where it is soluable it is absorbed. the waste is taken into the large intestine and gotton rid of
This is called absorption.
Where does the food go after it leaves your mouth?
While eating, food goes down your esophagus into your stomach, while air goes down your trachea and into your lungs.
What is the difference between heartburn and indigestion?
he main symptom of heartburn is a burning pain in the chest, just under the breastbone. Heartburn caused by acid reflux may be accompanied by other symptoms such as difficulty swallowing, coughing and wheezing, regurgitation of food or sour liquid and chest pain when lying down.
If you have chronic heartburn, it's likely caused by GERD, or gastroesophageal reflux disease. This condition triggers an excessive amount of gastric juices backwashing into your esophagus. Thus, they're present throughout your digestive system, which can cause you considerable discomfort. You might also have a hiatal hernia, which can cause heartburn. A hiatal hernia results when a portion of the stomach pushes through your diaphragm and into your chest. Obesity is a risk factor for chronic heartburn, as is pregnancy. Pregnant women frequently experience heartburn because of hormonal changes. In addition, the growing baby puts pressure on the mother's stomach. Certain foods such as tomatoes, carbonated beverages, peppermint, caffeine, chocolate, fatty foods, onions, and spicy foods can trigger heartburn. Alcohol and smoking can also cause acid reflux. You might experience a case of heartburn after eating too much or lying down too soon after eating. If you experience a prolonged case of heartburn and you've recently begun taking a new medication, talk to your doctor. The medicine might be causing your acid reflux, in which case you may be shifted to another prescription
Indigestion refers to a whole range of uncomfortable sensations affecting the upper abdomen and chest. Nausea, bloating, belching, mild pain and heartburn are the most common symptoms you'll experience. If your indigestion is accompanied by more serious symptoms such as sudden weight loss, vomiting blood or severe pain, it may be a sign of a more serious condition. You should get immediate medical attention if this happens to you
You'll find that indigestion and heartburn share many common causes. Like heartburn, indigestion can be a result of overeating, lying down after eating, smoking, alcohol or caffeine consumption, an overload of spicy or fatty foods, carbonated beverages and hiatal hernia. However, the difference lies in the causes. There are some triggers of indigestion which are unique and are unrelated to heartburn. Irritable bowel syndrome can cause digestive difficulties, as can gallstones and several forms of cancer. If your indigestion symptoms become frequent, you should talk to your doctor to eliminate any potentially serious underlying causes.
