Digestive System

Depending on the force of the return, this occurrence could be considered regurgitation or vomiting. If the food in the mouth is not forced out of the mouth, perhaps leaves a bitter taste in the back of the throat or heartburn, the occurrence would be considered regurgitation. If the food is violently forced out of the mouth, perhaps with nausea beforehand or dry heaves afterwards, the occurrence is considered vomiting.

In all actuality, tablet vitamins can take up to 4-6 hrs to breakdown in your body and only absorb at about 40% of what you put in. Tablet vitamins are full of binders and fillers and lubricants, all stuff your body does not need and most of which it can't break down and gets evacuated later. Capsule vitamins can take about 45-90 mins to break down and get absorbed about 50% and still have binders and fillers in them (including sawdust in some products). So in effect your spending a dollar and your body is only using up to 50% of the product.

The other type of vitamin out there is Liquid, they absorb alot better usually up to 80% or more.

There is a new type out there, actually been out for a quite a while called ISOTONIX, they are isotonic in nature, which means same pressure as blood, sweat and tears. This means they are passed right thru the stomach, they do not have to break down at all and they are readily absorbed w/in about 10 mins into the system from the small intestines. So you spend a $1.00 on the product and your body actually absorbs about .95 cents worth. You may pay more for a higher quality vitamin like this, but you get alot more out of it. Also keep in mind the body needs certain levels of vitamins daily too. For example, it needs 5000 IU of Vit D per day min. So when you buy a supplement that says 1000 IU and your body only absorbs 50% at best... That means you need to take 10 pills per day to get what you need. If you buy Isotonix Vit D and you take a capful, mixed with 2 oz of water, that is 5000 IU/day and your body absorbs 95% of it.

There is alot of products out there to waste your money on, be careful of what you buy!

Making a model of the digestive system will have to include a number of structures. Imagination will be necessary to find materials for the different organs. Sausage casings would make intestines in the model.

Yes, high doses can loosen bowel movements or cause diarrhea when you reach saturation point (saturation point varies from person to person). If that happens you can still take it, you simply need to cut back to the point where diarrhea does not occur.

Appendectomy (surgical removal of the appendix) is a standard medical procedure with low risks. However, as with any surgery, there remains the small risk of complications from the drugs used, infections, etc.

they are called accessory organs because they are not apart of the digestive tract but have a significant role in the digestive process

The human body will begin to digest the food that is ingested; however, the efficiency of breaking down the food into usable energy will be considerably hindered. At rest, the burning of calories is unsubstantial; therefore, consumption of food before sleep is not recommended. Yet, there are instances when eating may have some benefit. If it is difficult to fall asleep, or a day has been stressful, foods with whole grains such as oatmeal or bread and fruits like bananas have nutrients which actually slow down the processes within the body and trigger a "bedtime" response. Also, depending on what one has eaten the night before, there may be a feeling of "heaviness" in the morning, or a lack of hunger because the body was not given adequate time for digestion. This could, essentially, have a negative reaction on one's body for the entire day, upsetting the routine schedule ratio of food consumption to rest.

An ulcer.

The Gall bladder stores bile. Bile is made by the liver. Bile is essential for the proper digestion of fats. If fats are not properly digested, fat soluble vitamins are also not absorbed.

There are far too many to mention, but would include the brain, lungs, kidneys, liver, etc.

If you are asking about organs that are related to the digestive process, then you are probably referring to the accessory organs of digestion, and there are several. The liver, gallbladder, pancreas, and salivary glands are probably the major ones, though this list could also be endless if you consider the special senses.

Materials not absorbed in the colon are excreted as waste products in the feces.

The peristalsis which is a wavelike muscle contraction

Mechanical digestion starts when food is chewed physically by the teeth (grinding and tearing the food), and the remaining steps of digestion continue from then on.

Because the body needs to get rid of waste, (food that is not used.) If it didn't you would be poisoned.

Not usually but you could ask your surgeon.

Gallbladder is a sac for holding some bile that is produced by the liver for the body to brake down and digest fats. with or without a gallbladder, the liver is still producing bile; however, the bile is not as readily secreted in the body, and the liver can become overwhelmed when it faces with a large amount of fats (especially saturated and hydrogenated fats). This leads to the difficulty of digesting fats; small amount of fats can cause discomfort. Secondly, the dumping of bile is now not as easy to be regulated which can cause diarrhea after eating. Finally, after the gallbladder being removed, the bile produced by the liver becomes thick and sluggish, painful symptoms and bile stones in the liver (particularly in the common hepatic duct) can occur.

The food materials is ingested into the cell via endocytosis which is digested by lysosomes which contains various hydrolytic enzymes. Waste materials so formed after digestion is excreted by cell by process called exocytosis.

Enzymes contribute to chemical digestion. They are produced by the pancreas and together with bile, chemically change food into molecules so that it can be absorbed easily by the body.

RESPIRATORY SYSTEM is the process of respiration. The lungs is the main organ of the respiratory system because it receives oxygen and take out the carbon dioxide. DIGESTIVE SYSTEM is the process of digestion. The main organ is the stomach because this is where the digestion occurs.

I think it really all depends on what type of food you have in that mouthful.

The epiglottis in the Oral Cavity

I think you mean "does"
It starts the moment you put the food in your mouth. Your mouth is part of your digestive tract. Mouth, esophagus, stomach, small intestine, large intestine, rectum.
