What produces bile that it secretes into the duodenum via the bile duct?

Bile is produced in the liver and stored and concentrated in the gallbladder, then transported to the duodenum via the bile duct when needed.

The bile salts break down fats (called gall) via emulsification, which enlarges the surface area of the fats, and allows for more efficient digestion of lipids by enzymes in the duodenum.

Bile is a sticky semi-thick substance that is dark in color. It is a bitter, alkaline, brown/yellow/green fluid. It is an alkaline liuid composed mostly of water, bile salts, bile pigments (bilirubin, from the breakdown of hemoglobin), fats, and cholesterol.
Presuming that we are referencing a HEALTHY HUMAN BEING (post infancy) then: BILE is PRODUCED & SECRETED by the LIVER and EXCESS amounts will be STORED in the GALL BLADDER the liver The liver. It's then stored by the gallbladder. stomach
Bile is made by the liver and stored and released into the intestine in response to dietary fat by the gall bladder.

Stomach

What tube connects the mouth and the stomach?

The esophagus (also spelled Oesophagus) is the tube that connects the mouth and the stomach. It works through continuous wavelike muscle contractions known as peristalsis, along with downward gravity, to move food and liquids from the mouth and throat into the stomach.

Why does the human body create solid waste?

An active person will excrete as waste the excess of food that they eat.

As backpacker, who has been on trips of several weeks carrying all supplies on the back, I assure you that you excrete little.

This is partly because the food is probably low-residue and carefully chosen, but if you're exercising a lot (as a backpacker does), then your excess is minimized.

On a 21-day trip, our party of 6 went OK (including 7 days snow-caving) on a diet of 24oz per day each. A little less than 700g/day.

[One slightly overweight member, who lost his tobacco during the trip was certain that he'd lost weight, (for his belt was more slack) so on reaching civilization again, his first move was to weigh himself. And was disappointed to find he'd gained weight!. In a 21-day period you can lose fat and put on muscle, which is more dense than fat.]

What happens if you eat rocks?

They'll just pass through you if their small enough. If they're too big, they'll get stuck in your digestive tract (most likely your small intestine), then you'll get really sick and have to go to the hospital to get it surgically removed.

Do cold drinks help in digestion?

Alcohol can serve as a digestive aid. Liquid inside your stomach fairly quickly reaches your body temperature, so any temperature difference is unlikely to contribute much to the digestive process. Switching from hot to cold is very hard on teeth, which contract and expand with the temperature differences. For the sake of your teeth you should drink water that is close to room temperature, especially after meals when it can help wash sugars and food particles out of your mouth.

What carries bile into the duodenum?

The gallbladder stores bile and when it is needed it is excreted through the common bile duct and joins the duodenum at the ampulla of vater.
The gallbladder stores bile and when it is needed it is excreted through the common bile duct and joins the duodenum at the ampulla of vater.
Bile is made in the liver and passes through bile ducts and into the common hepatic duct which carries it out of the liver. From here, it can pass down the common bile duct into the duodenum or take a detour into the gallbladder via the cystic duct.

Why does my burp smell like rotten eggs?

The first common, and most serious, cause of sulfur burps is an infection from Helicobacter pylori or Giardia. Helicobacter pylori is a bacterium that can cause serious infection and ulcers within your stomach. Giardia is a parasite that makes its home in your lower intestine and reproduces to cause serious stomach problems. The most common ways to introduce either of these infections is through unclean water sources or poor hygiene and oral-fecal transmission. Sulfur burps can be a symptom of both of these infections.

Some food may also cause sulfur burps. This is especially true in those with diets high in protein. The main culprit in food-related sulfur burps is hydrogen sulfide. If your stomach takes longer than normal to process and expel a meal high in protein, the lingering food can actually start to build up acid and cause a chemical reaction that creates hydrogen sulfide. This can also explain why someone suffering from sulfur burps may feel bloated. In these cases, the sulfur burps usually go away once the lingering protein and hydrogen sulfide is expelled.

How long do you have to wait after eating to shower?

Digestion requires good blood flow and digestion generates heat. If one takes a warm shower, does exercise or goes for a swim, the blood needs to be diverted to the skin surface for cooling purposes. This interferes with digestive process and you can end up having a stomach ache, can faint or even have a heart failure if you are weak.

Though most people would see no ill effects having showered right after a meal, but weak or old people can have a different reaction. So a healthy habit is to wait for about 30 mins after a meal before taking a shower.

The reason someone would faint would be because there is not enough blood flowing to the brain. Digestion requires a high percentage of blood and when you take a warm shower the blood vessels dilate in order to cool down the body by releasing the heat from blood to the skin. More blood flows through those vessels and since so much blood is being used elsewhere the brain may be lacking blood and the bodys reaction to this is to faint because fainting will keep the body level and the blood will flow evenly. This may not affect a lot of people but people with health concerns and also people with bad circulation may have problems.
