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.

What role does bile salt play in the digestion of fat?
Bile assists the digestion of fat.
Bile separates fat molecule from one another and prevents them from clumping back together. This makes them more susceptible to actual digestion by a pancreas enzyme called pancreatic lipase.
further, bile is an alkaline and can be used by the body to neutralize digestive acid.
seriously... if you reeeally wanted to know that then why don't you try it yourself.
What organ is not needed in the digestive system?
The esophagus because the esophagus carries the food to the stomach.
Also the Large intestine. The only thing that occurs here is absorption of water,
salts, and minerals. This organ is about 3ft long.
What food molecules go into the blood?
The small molecules such as digested fat, carbohydrates and proteins.
What are the effects of junk food on digestive system?
Obesity can increase the risk of gastroesophageal reflux and esophageal cancer. Obesity can increase the risk of liver disease (non-alcoholic fatty liver).
Kill obesity before it kills you
It is the toxic mischief of the flesh itself.
Experts has studied the reasons why there are an increasingly amount of young people who has died for decades, and the explanation seemed apparent.
Carrying all that extra weight puts a gravely strain on the heart and other organs. It not only contributes to the arthritis and sleep apnea, it is a minor hazard compared to the complex and deceitful damage wrought by the oily, yellowish globs of fat that wraps human bodies like never before.
Fat tissues are not just a depot; in fact it is an alarm to other parts of our body. It is now recognized to be the body's biggest endocrine organ, and its sheer volume is impressive even in normal size people.
Standard percentage of fat for (trim) women - 30%
Standard percentage of fat for (trim) man - 15%
That is enough to keep someone alive without eating for 3 months.
The fat cell's main job is to store excess calories as fat. When people grow obese, their fat cells swell with fat and can grow up to 3 times the normal size.
Obesity is a huge and growing killer in the United States, just behind smoking. Moderately obese people live 2 to 5 years lesser than the average people. For the morbidly obese, the reduction in life span may be 5 to 10 years.
The greatest single threat caused by obesity is heart disease. People with a body mass index (BMI) of over 30, triples the usual risk. Researchers have confirmed that fat cells' chemical flood is a contributor to heart attacks, heart failure and cardiac arrest.
Undeniably, weight increases blood pressure. More weight also means the extra force needed to push blood through more blood vessels that is required to nourish the extra flesh. Fat triggers high blood pressure by narrowing the blood vessels in several chemical ways. It produces a substance called angiotensinogen that is a powerful constrictor and stimulates the sympathetic nerves to squeeze the circulatory system.
What organ of the digestive tract absorbs more nutrients than any other organ?
Your intestine absorbs more nutrition than any other organ. It is about 20 feet long. But the surface area for the absorption is very large. It is estimated to be about 2750 square feet.
Creamy semifluid mixture of food and digestive juices?
Its called Chyme. Its a mixture of food, at some extent semi-digested under the influence of Pepsin and hydrochloric acid, and saliva from mouth.
What is end product of amylase in digestion?
Amylase breaks down starch, and therefore the product of digestion is maltose.
Why after taking indigestion tablets do you burp?
The reaction of the acid in your stomach with the metal carbonate (usually calcium carbonate) in the indigestion tablet produces carbon dioxide gas. This needs to be released somewhere as we do not use it in our bodies.
Yes. Digestion is not depended on orientation of the person (or the astronauts would be really hungry!)
What foods last the longest in your digestive system?
Lipids (fats & oils), as they have the most complex structure to break down.
Simple sugars are the easiest, followed by complex sugars, then starch, then proteins, then lipids.
It can take a few minutes to absorb simple sugars, a couple of hours for starch, 6 hours for proteins and 8 hrs or more for lipids. That's why low fat diets can make people go hungry.
What is the process that results from the digestion of starch?
Starch is simply a carbohydrate or sugar. It is found in two forms: amylopectin and amylose. Both of these are polymers of glucose with α(1→4) glycosidic bonds. In humans, enzymes help break these down into single monomers of glucose and then are fed into glycolysis for many cells. After going through the glycolysis and the rest of cellular respiration, the body ends up harnessing the energy of breaking down this glucose into ATP , which functions as the major energy currency of a cell.
Which team refers to the loss of intestinal peristalsis?
Ileus is a functional rather than mechanical obstruction of the bowel. It is a lack of propulsive peristalsis (wave-like movement) of the bowel. It stops the movement of bowel contents downward. There is abdominal distention and an absence of bowel sounds.

Why does your stomach have folds in its walls?
Inside the small intestine thair are lots of hair like things that help with digestion. Now if you get a peice of paper (recycle after please) and fold it so that it ends up as a strip. now if you look it from above the size of the paper has shrunk. the small intestines use the same idea so the can fit more hairs into a smaller area
What is the name of the pipe that food goe down after you swallow it?
The name of the tube that food goes down when you swallow is called your esophagus.
Yes Maltose can be digested by the human body. Cellulose can not
What describes the process of starch digestion?
When starch enters the mouth, it is acted upon by salivary amylase which is an enzyme that breaks starch down into maltose. It is not fully digested yet.
In the stomach, low PH levels caused by the hydrochloric acid denatures the salivary amylase, rendering it useless for starch digestion. The starch remains in the stomach, until it's churning action turns starch into chyme (liquefied food) The purpose of this is to increase the surface area to volume ratio, so as to increase the efficiency of enzyme action.
The starch leaves the stomach, and enters the small intestine. In the intestine, it is acted upon by the intestinal amylase, and the pancreatic amylase, which fully breaks down the starch into maltose. Afterwhich, the maltose is acted upon by maltase, which breaks it down into glucose. When this is done, it can be absorbed easily by the villi into the bloodstream.
