Digestive System

The pharynx is the section of the throat between the skull and the esophagus that propels food when swallowed into the esophagus. The epiglottis at the bottom of the pharynx pivots to send food to the esophagus or air into the lungs by way of the voice box (larynx).

it takes around 45 minutes for water to pass through but if its a slightly thinker liquid it takes around 46 minutes it takes around 45 minutes for water to pass through but if its a slightly thinker liquid it takes around 46 minutes

a mechanical breakdown is when you manualy breakdown something,without using any objects. for example chewing your food is a mechanical brekdown or ripping a paper. And when you are breaking it down it fells like you do not feel anything.

The soluble portions of food are absorbed by the small intestine into the bloodstream.

there are different things you can do. here are a few:

drink mint tea

drink a fizzy drink very fast thins will make you burp to get rid of the wind

drink a mixture of lemon juice, water, tea spoon of syrup and a tiny bit of salt

rub your stomach in circular motions

The stomach acts as a reservoir for food, churns the food, mixes it with gastric juices, and gradually releases the food into the small intestine. Some water, alcohol, and glucose are absorbed directly through the stomach into the bloodstream. Enzymes secreted by the stomach help break down proteins and fats into simpler substances. Hydrochloric acid secreted by the stomach kills bacteria and prepares some minerals for absorption in the small intestine. Some food may leave the stomach one minute after it enters, while other parts of a meal may remain in the stomach for as long as five hours.

The digestion of food through the alimentary canal involve a series of chemical and physical changes. In the example of pizza its bread component undergoes chemical changes as it is digested by amylase enzymes in saliva. Other chemical changes include hydrochloric acid of the stomach "attacking" and digesting proteins found in the pizza.

digests and breaks down your food to be further processed by other organs, and kills germs which have entered the stomach, say when you swallow when you have a cold/the flu (flem)
breaks down your food so it can turn into energy

Contrary to belief, alcohol is good for you. At least, in moderation. if you drink a small amount daily it's proven to be good for you.

the large intestine is 1.5 meters long, while the small intestine can be from 4-7 meters long. Though it is called the small intestine, it is actually the longest part of the digestive tract.

Micro-organisms, such as bacteria, are able to digest cellulose.

No mammals are able to digest cellulose. This is because cellulose contains a β(1,4) linkage that no mammalian enzyme can break. This is why herbivores must have symbiotic bacteria somewhere in their digestive system that help them break down cellulose.

Food, on its own, is not in a form where your body can use it. Food needs to be broken down into small molecules of nutrients for the body to be able to absorb it. The digestive system processes food into useable nutrients and distributes them into the blood stream to go to different parts of the body.

Bile does NOT digest fats. It is NOT an enzyme, therefore, it cannot break down lipid molecules into smaller nutrients. What bile does is it HELPS enzyms to digest fats by emulsifying the fat molecules. This means the surface area is increased, thus enuring a more efficient and quicker digestion of the lipid molecules. This process takes place at the top of the small intestine, in the duodenum, as this is where bile is secreted from the gallbladder, through the bile duct and onto the food.

The liver and the pancreas are two organs that are fundamental to digestion. Bile from the liver helps in the digestion of lipids(fats) and enzymes conveyed from the pancreas help in the digestion of proteins and carbohydrates.

The muscular system is the mechanical force behind the digestive system. Beginning when you take a bite, your muscular system aids your digestive system. Chewing and swallowing are done by the muscular system; muscles surrounding your stomach churn up food to aid digestion; muscles transport digested food through your intestines and eventually out of your body. (The muscles for chewing and swallowing are voluntary muscles; the rest are involuntary.)

It can take very long to digest, up to 40 hours. But on liquidy and soft food such as fruits, it can take only 2 hours!

eat healthy foods and drink healthy drinks and dont smoke

step1: eat right, consume protein, carbohydrates in right amount and make sure you get plenty of fiber. Eat on right time schedule.

step2: drink plenty of water and avoid sugary drinks or those that contain caffeine. Limit alcohol drinks to 2 times a day.

step3: exercise. Moving around helps things move along

step4: be alert problems that don't go away. Symptoms such as heartbum, constipation and stomach upset can be caused by things as minor as bad chili dog or as serious as cancer. If you've been suffering for more than a couple of weeks, see your doctor.

step5: get scheduled tests. your doctor will tell you when you need to have regular coloniescopies to find and remove precancerous polyps. If your doctor recommend you other tests, get those as well.

step6: quit smoking. Among the many reasons to quit smoking, it contributes digestive problems such as heartbum, ulcers, and gallstones.

A number of things aid in the movement of food through the gut. Peristalsis is a huge contributer, it is small muscle contractions that occur throughout the digestive system. It help moves food down the esophagus. The cardiac sphincter then allows food to enter the stomach where food again is mixed and moved by peristalsis. Food sits in the reservoir of the stomach as chyme(the mixed up mush of the food we ate) where finally the pyloric sphincter allows it into the small intestine without backing up. Again peristalsis works to push it through the intestines to eventually be excreted as waste.

The breakdown process of starches takes place in the mouth. We chew our foods and mix it with saliva. This mixture enters the stomach and enzymes such as amylase breaks down starches further. So, the mouth is the first organ to break down starches.

In digestion, they break down substances into smaller molecules, so that they can then be absorbed into the bloodstream.

Carbohydrase emzymes such as Amylase break starch down into glucose.

Lipase enzymes break down lipids into fatty acids and glycerol.

Protease enzmes break down protein into amino acids.

No, it is generally not considered healthy to have such infrequent bowel movements. In general a health care professional would suggest that someone should poop within three days of the last time. Pooping only once a week might be a symptom of constipation--or it might be perfectly normal for a given person. Variation in the intervals is normal and "regularity" is individualized to each person. But, as a rule of thumb, if a BM does not occur within three days of the last one, it would be time to take measures to relieve the situation. The most common factors that affect frequency and regularity are food consumption volume, fluid intake, and amount of fiber in the diet. Chronic constipation can also be indicated by small amounts of stool that are relatively dry, hard, difficult to pass, and/or shaped in small balls. Assuming the diet is regular food and not just clear liquids, relief can be as simple as increasing fluids (especially noncarbonated, and not alcohol, coffee, or tea, which are natural diuretics and deplete the available fluids for the digestive process), or eating more fiber rich foods to relieve the constipation (e.g., prunes, prune juice) and increasing fiber intake as a matter of course to prevent future constipation (e.g., bran cereals, fruits, vegetables). After two days without a BM, you might try those methods. But if ineffective and necessary, next you could try a gentle laxative like the soluble fiber types (e.g., Citricel or Metamucil or generic equivalent). Follow the instructions on the package labels. You will eventually learn what works best for you. Sometimes a stronger laxative may be required, but your system can get used to them and not work well without them if used too frequently. Another over the counter remedy is a pre-mixed small bottle of enema solution (e.g., Fleet's-type enema), easily self-administered. Some prescription and over the counter medications can contribute to chronic constipation, consult your health care professional, especially if the listed side effects on the label include constipation. If these changes in diet, fluid intake, and regular exercise are not successful to produce consistent regularity at least every three days, or if you see blood in the stool, or if the feces looks tarry black, or any other changes to your bowel habits occur, it would be advisable to see a health care professional right away.
