Digestive System

our teeth break down food physically which is called mechanical break down

The alimentary canal consists of the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. In adults, the alimentary canal is about 30 feet long.

Other names for the alimentary canal include the gastrointestinal (GI) tract, digestive tract, alimentary tract, and nourishment canal.

Starch is being digested.

The liver is the organ the makes the liquid bile. It helps digest fats and lipids.

Fibre is a carbohydrate that the body cannot break down.

It is very important for functionality of the digestive system and to control glucose absorption and other functions that we are learning about.

Fibre is in a form of soluble and insolubles. Both are needed and beneficial to our bodies

Phenylketonuria

Chylomicron

Chewing food takes from 5-30 seconds

Swallowing takes about 10 seconds

Food sloshing in the stomach can last 3-4 hours

It takes 3-6 hours for food to move through the small intestine

The remaining water in the food is sucked up by the large intestine can last 18-24 hours

The waste of the food is then stored in the colon, where they remain,

usually for a day or two, until the feces are expelled by a bowel

movement through the rectum.

I know that it takes about 8 hours to get through both the stomach and the small intestine. And most digestion occurs in the small intestine. So, probably about 2-3 hours. Remember, the stomach only has the enzyme to digest proteins, so why on earth would a lot of digestion occur in it?

It is a hormone which controls the quantity of pancreatic juice and bile in small intestine. It causes the release of digestive juices into the intestine by controlling sphincter of oddi (valve between ampulla of vater and small intestine). Ampulla of vater is formed by the union of common bile duct and pancreatic duct.

A Ostrich's small intestine is about 30cm long.

Because the Small Intestine has a HUGE job in the Digestive System. Then you won't be able to excrete.

Apart from the active ingredients most pills are made up of a basic (alkalynic) material such as chalk or some form of Xcarbonate (X = magnesium/calcium etc.) When the pill hits the highly acidic environemnt of the stomach (ph=2) then react with the acid and dissolve. Some pills have an enteric coating that is highly resistant to the stomachs acid (hydrochloric acid) and so pass undisolved into the small intestines where enzymes then eat the coating and the pill disolves there instead. This is important because lots of medicines would be destroyed by the acid in the stomach and so would never get to the tissues that need it.

It depends on where in the digestive cycle what breaks them down. Bile makes very large fat globs into very small ones. This allow enzymes called lipases to finish breaking them down so that they can be absorbed.

Gastrointestinal tract

The digestive tube is an ambiguous term I have heard it used in reference to many things and so will attempt to name them all. The most common use of digestive tube is when someone is talking about the Esophagus. This is the tube that connects the Pharynx (the top part of the throat) to the top of the Stomach. It is clever in that it has a method of propulsion for the Bolus (food particle that is swallowed). The motion is caused by the part of the esophagus in front of the bolus relaxing and the part behind contracting to push the food along. This motion is called Peristalsis. Another common use of the digestive tube is when a person is referring the the entirety of the Gastrointestinal Tract (also known as the Digestive Tract). This includes everything from the oral cavity to the anus and as an overall function of breakdown and absorption of nutrients within food. A less common use, although perhaps the most valid, is when someone is referring just the Small Intestines. This is ironically much longer than the large intestine and is the tangled mess of tubing that sits at the bottom of the abdomen. In reality this, not the stomach, is where most digestion takes place and all the absorption of nutrients takes place. The majority of the digestive fluids are added to the small intestine in a section at the very start called the Duodenum (very short, only around 15cm) and most of the absorption takes place in the Jejunum and Ileum (much longer, around 8m) which eventually connects to the Large intestine. In short the "digestive tube" could be referring to 1)The Esophagus 2)The whole of the Gastrointestinal Tract or 3) The Small intestine. The term is however not a recommended one because of its ambiguity.

It begins as soon as you put a piece of food in your mouth. First part of digestion is the surrounding of the food by the saliva. This helps in breaking down and dissolving the food for further processing.

yes

Digestive system breaks down your foodstuff into small particles so that they can be absorbed into your blood stream.

So the body can absorb nutrients that are in food. Digestion breaks down the nutrients into the most simple forms so the body can metabilize the necessary vitamins, proteins, carbohydrates, fats, sugars, etc, tc, etc. Without digestion the body could not use the food in the form it is ingested.

it first changed in to a small moleucles or compounds known as miscilles which are taken by cell

Mucosa

Bile is produced - produced in the liver and stalled in the gall bladder

A person has "good" bacteria in the large intestine. These are often called probiotics. A person also has many on the skin and they crowd out harmful ones.

One is large and one is small

Indigestion, also know as heartburn is an irritation of the lining of the stomach, and/or duodenum (first part of small intestine). This can be caused by stress, nicotine, illness, caffiene, and alcohol. Certain medications can also cause this symptom, in particular aspirin, non-steroidal anti-inflammatory drugs such as Advil, Naprosyn, Alleve, etc.
