Digestive System

There are a few top contenders, but it is suspected that the hardest food for a human to digest is bread. In order to digest food, enzymes are needed, which are secreted by the pancreas. Because bread has no naturally occurring enzymes (unlike a lot of other food) the pancreas has to work exceptionally hard, producing extra enzymes to break down the bread. Other food products that are hard to digest include pork, beans, broccoli and whole-milk hard cheese.

it occurs in the glomerulare (Bowman's) capsule.

Exercising regularly, drinking plenty of water, and eating a well-rounded diet are excellent ways to promote healthy bowel function. Many people think they need to have a bowel movement every day, but the reality is that people's bodies vary, and healthy adults range from three bowel movements per day to three per week.

Your symptoms seem to fit the definition of constipation if you have less than three bowel movements per week, a subjective sensation of hard stools, a sensation of incomplete bowel evaluation, or straining during more than 25% of bowel movements. Long-term constipation can result in damage to your large intestine or hemorrhoids caused by blood-vessel breaks from straining to pass hard stools.

What is digestion

intestinal crypts

The thoracic cavity is divided into right and left parts by a median partition called the mediastinum and contains the heart, the thymus, the trachea, the esophagus, and other structures such as blood vessels and nerves.

It is a long tubing which allows food to be tranferred to the small intestine through peristalsis. No digestion occurs in the esophagus.

+++ The first sentence is incorrect. It is the tube from mouth to stomach, not to the intestine, but it is right that digestion does not occur within it.

Peristalsis is the series of muscle contractions that move food through the intestines.

The mucus on the lining of the stomach protects the stomach from the acids that break down the food. Without this mucus the acids in the stomach would begin to eat away at the lining of the stomach causing stomach ulcers and many other problems.

Vomiting to lose weight is always dangerous. There is no safe way to do it.

Have an ERCP to make sure there is no blockage in your bile duct

No, photosynthesis and digestion are two separate things.

Autotrophs (also known as primary producers and plants) are organisms (such as grass and phytoplankton) that can create their own food and which typically use photosynthesis to synthesis (make) nutrients like sugar and carbohydrates (its food). In photosynthesis, energy from sunlight is used to convert carbon dioxide and water into sugars (which it lives off of) and oxygen gas (which is expelled for animals to breath).

Heterotrophs, on the other hand are, animals that feed of of other organisms. They consume autotrophs and/or other heterotrophs and digest them to get their nutrients. In digestion, food may enter the mouth, become broken down in the stomach, and have the nutrients absorbed in the intestines, cumulatively called the digestive track.

Depends on the type of surgery, the narcosis, the patient, and the postoperative medication. It can be hours, but might be days. Morphine and lookalikes tend to slow the digestive system down (though newer derivates should be better).

When there is damage to the liver, it attempts to repair itself. The remaining cells (mainly hepatocytes, but also oval cells) - undergo mitotic division in order to replace damaged or dead cells. This process is known as hyperplasia. When hyperplasia occurs in the liver, it results in nodular formations of new cells.

A cirrhotic liver is an end-stage liver. It cannot be repaired, and if the person is to live they will need a transplant. A cirrhotic liver will be diffusely (all-over) covered with nodules, where the liver has attempted to regenerate. It will also have scar-tissue and fibrosis as a result of the damage to the liver.

Because they do not have the digestive enzyme to break down cellulose.

Unlikely, unless more than gas comes out at the same time. Influenza viruses are not airborne, which would be required for the virus to somehow travel on the flatus from person to person. Unless there is much more than air and gasses expelled, it would not be possible.

When a person sneezes or coughs, droplets of respiratory secretions are expelled in a mist with some larger drops. Viruses can be contained in these respiratory droplets and that is how you can catch the flu from a person who coughs or sneezes and you breathe in the droplets from the air, or you touch a place where the droplets landed when they fell out of the air. The droplets are much heavier than air and will fall to the surfaces around the person who failed to cover their mouth and nose with a tissue (shame on them). Under most conditions, keeping a distance of around six feet from a person who is sneezing or coughing will keep you outside the distance the droplets carrying the virus can travel in the air before falling to the surrounding surfaces.

The person having flatulence is hopefully wearing clothing in your presence, which would act similarly to the tissue covering your mouth and nose when coughing and sneezing and the clothing would catch any "secretions" (fecal material) that might get expelled along with the air and gasses in the passing of the intestinal gas.

So, for you to catch swine flu through flatus, the person with the flatulence would have to be naked, and expelling droplets and not just gas. You would have to be close enough to the source to breathe those droplets in directly from the air, and that would be much much closer than six feet, because the force behind flatus is insignificant compared to the force of a sneeze or cough. It would likely be required that your nose be within a foot of the anus to be able to breathe the rectal fecal droplets. Otherwise, you would have to touch something the droplet fell on, and then transfer the virus contained in the droplets to your eyes, nose, or mouth with your hand. I know that I would be very unlikely to put myself in that place or do those things, and hopefully you and the person with flatulence would also not likely be in those positions.

Additional flatulence trivia:

The components of flatus are nitrogen (the most prevalent gas in the air), oxygen, carbon dioxide, hydrogen, and methane. Each person will have a different combination of those gases, and not all people have all gases in their flatus. That is dependent on the foods eaten, drinks consumed (carbonated drinks increase the carbon dioxide content), bacteria present in the gut, and some genetic components--since there seems to be an hereditary relationship to the production of methane in humans. These are all mostly odorless gases. The things present that create the odor are mostly sulfur from hydrogen sulfide, carbonyl sulfide, butyric acid, and skatole and indole which are compounds high in nitrogen.

In order: Mouth, Asophogus, Stomach, Pancreas, Gallblader, Small Intestine, Large Intestine, Rectum, Anus.

Mostly in the stomach where food is Mechanically (physically) changed when the stomach muscles squeeze the food. Chemical change also happened when the acids in the stomach separate nutrients, break down food, and kill bacteria. When the two are combined, the food turns into a soupy-like mixture called chyme, which has alot of acid in it from the stomch. I hope that's what you wanted.

The semi-digested food becomes almost liquid in the stomach, which produces digestive jucies.

proteins- 2nd in stomach due to enzymes
