Digestive System

Digestive System is the category for questions regarding the breakdown and absorption of food-stuffs in our alimentary canal. Questions about the stomach and intestines can be included in this category.

7,599 Questions

During digestion organic molecules are broken down into what two components?

Organic compounds are broken down into at least four different sub-components:

* lipids * amino acids * carbohydrates * fibre, sometimes called roughage

The wording of the question seems to infer you already know the answer you think it is, and if you were going to say CO2 and H2O then you're sorely mistaken.

Factors affecting the digestive system in fish?

DIGESTIVE SYSTEM

The digestive system of fish is similar to the digestive tract of other animals. Carnivorous fish have short digestive tracts when compared to herbivorous fish. The stomach and intestines contain submucosal eosinophilic granular cells. The function of these cells is unknown. Some species of fish (Salmonids) have pyloric ceca, which are occasionally confused with parasites. These ceca secrete the digestive enzymes required to digest some food. Fish without the pyloric ceca have digestive enzyme production in the liver and pancreas. It is not possible to divide the intestine into large and small intestine.

The liver does not have the typical lobular architecture that is present in mammals. In many species of fish there are areas of exocrine pancreas (hepatopancreas) that are present near the small veins off the hepatic portal vein.

The pancreas is scattered in the mesentery, primarily near the pylorus.

Why would not chewing food enough make it harder for the digestive system to do its job?

The larger the food is the harder it is for the acid in the stomach to break down the food. When you chew your making the digestive job easier

It all a matter of surface area. Stomach acids work on the surface of the food, can't work on anything that it can't get at. So the less surface area the food has the longer it will take the acid to 'work it way through' the out-side food to the inside food. This is why things chew.

What metal is used in hospital scans?

Barium sulphate is used in hospital scans to show the digestive system. It is very important in CT scans.

When having a gallbladder attack does it hurt to breathe in?

yes, it does! its like someone is squeezing your stomach, your heart, and back. it hurts to breathe, it hurts to move, it hurts to talk. it just hurts!

What are some causes of functional dyspepsia?

Functional dyspepsia is also known as indigestion and affects about 15% of the population. It is commonly caused by the muscles in the gastrointestinal tract or the nerves not functioning properly. Some common causes that can lead to discomfort are overeating, people that travel a lot and eat different cuisines, and going to bed right after eating a meal.

How does food get digested in the stomach?

well the liver squirts an enyme called amalaz into the stomach and then it get churned around by the hydrochloride acid then it is parcely dissolved and sent into the mall intestine

Why dont most parasitic flatworms need a complex digestive system?

Parasitic flatowms typically live in the digestive system. Surrounded by pre-digested nutrients, they can easily absorb basic nutrients that they need to maintain homeostasis. In other words, they are borrowing the host's digestive system.

What are the functions of the digestive system?

The human digestive system, also called 'Gastro Intestinal System' (GIT) includes everything from 'Palate' to 'Rectum'. Following are the components of this system;

1. Mouth

2. Oesophagus

3. Stomach

4. Small Intestine

a. Deudenum

b. Jejunum

c. Ileum

5. Large Intestine

a. Ascending Colon

b. Transverse Colon

c. Descending Colon

d. Sigmoid Colon

6. Rectum

Different parts of GIT secrete different types of chemicals which help in the digestion of food. These chemicals are called 'Digestive Enzymes'. They may help in digestion by breaking or diluting food particles by certain biochemical reactions.

Would you have an increased appetite shortly after conception?

I have done some cursary (sp?) research on this, as my husband and I are tyring to conceive -- so I'm noticing every little thing. It seems that there are as many early pregnancy symptoms as there are women experiencing them. HOWEVER, increased appetite is one that some women cite. (I googled the terms "earliest sign of pregnancy" and "increased appetite" to find some anecdotal info, and some medical "help" sites). Good luck (either way, if you're wishing YES, or hoping NO)! C*

What stores digestion juices until they are needed by the small intestine?

There are several digestion juices, starting with saliva in the mouth, but the digestion juice released into the small intestine is bile which is stored in the gall bladder.

What are two jobs the digestive system does for your body?

The digestive system processes your food and extracts nutrients from it.

What makes food turn brown in your stomach?

It is being cooked chemically by the acids and bases that react with it, and the resulting slurry coats every surface.

How do you treat a fungus infection in the digestive system?

There are many antifungal medications both natural and prescribed.

The coconut derived fatty acid known as Caprylic Acid is available over the counter and is often used as an alternative medicine.

Nystatin a broad spectrum antifungal along with Itraconazole and fluconazole are both effective. In all cases speak with your physicianas severe fungal infection of the bowel can cause leisions and further infections.

Are Animal-like protists grouped by how they digest food?

Yes, they are grouped by the process of the digestive system in the protists body. Yes, they are grouped by the process of the digestive system in the protists body.

What is indigestion and what usually causes it?

Indigestion, or dyspepsia, is any pain or discomfort felt in the stomach, usually associated with difficulty in digesting food. It can be accompanied by a burning or pain in the upper stomach as well. There are many causes to indigestion, including lifestyle choices (i.e. smoking, stress, drinking too much alcohol, eating too much or too quickly), medications (i.e. pain killers, aspirin, birth control, etc.), and diseases (i.e. Gastroparesis, irritable bowel syndrome, GERD, etc.).

What are the effects temperature and pH level have in the efficacy of digestive enzymes?

As you increase the temperature at first the activity of an enzymes will also increase, so the reaction will go faster. At a certain temperature, called the optimum temperature, the enzyme will work at its maximum rate. Above the optimum temperature the enzyme activity decreases. This is due to the loss of shape by the enzyme molecules, a process called denaturation.

In mammals, most enzyme shave an optimum temperature of about 37 oC.

Roughly speaking, the rate of an enzyme reaction doubles for each 10 oC rise in temperature, until the optimum temperature is reached.

pH affects enzymes in a similar way. At a low pH many enzymes have a low activity. As the pH increases the enzyme activity increases until the optimum pH at which the enzyme has maximum activity. Above this pH enzyme activity decreases. These effects are also dueto denaturation of the enzyme molecules at extreme pH values.

Many enzymes work best at around pH 7.0. An important exception is pepsin, a protein-digesting (protease) enzyme in the stomach. This works at low pH values such as those found in the stomach (around pH 2.0), due to the presence of hydrochloric acid.
