Why don't you digest peanuts fully?

Humans can not fully digest nuts because they contain phytic acid. Herbivores like cows and sheep can digest phytic acid but humans canÕt. Phytic acid also inhibits the enzyme trypsin, which is needed for protein digestion in the small intestine.

Can anyone live without fingernails?

yes, you will not die without them. however, all the nerve endings in your fingers end under your nails and you would have some extremely sensitive fingers constantly exposed! I would imagine it would be quite painful. but again, it would not cause you to die.

Why not? The finger-tips will be painful only a few days, extremely sensitive only a few weeks. I'd like the look and I am dreaming of...

Actually "airplane food" is quite tasty. It is where it is at that makes it seem to taste different, in an airplane you are breathing in somewhat dry air.

A mouse requires about 2 to 3 grams of food per day in order to survive. The mouse will starve in just a few days without that amount of food.

What happens to the undigested food in the large intestine?

The undigested food is passed on to large intestine where water is absorbed from the undigested food and it become almost semi-solid. Now the undigested food is acted upon by putrefying bacteria which convert the undigested food into faeces are stored in the rectum from where the egected out through anus and it is controlled by anal sphincter.

What is the redwoods digestive system like?

Trees and other plants do not have digestive systems per se. Instead of eating food and digesting it for energy like animals do, plants make energy from the sun's energy in a process called photosynthesis.

Does oatmeal help you go the bathroom?

Oatmeal, like other grains, contains fiber which helps food move through the digestive system and can help you go to the bathroom.

What happens in the process of digesting chicken roll?

The process starts with the crushing and pulverizing of the chicken roll in the mouth, saliva lubricates things allowing the process to be very thorough. The teeth pulverize and crush then the motion of the jaws turns and rotates the food preparing it for the next bite. Once the food is sufficiently pulverised and masticated it is squeezed into lumps, the lumps of masticated food are swallowed and lubricated by more mucus get pushed down the throat and through the oesophagus and into the stomach by peristalsis.

The stomach mixes the food with digestive acid breaking it down at the chemical level into a 'choam'. The stomach isn't just passive, at one level it is wobbling shaking the mixture, on a bigger scale it is churning it constantly, on the biggest level every few minutes the stomach squeezes the whole lot though itself in a wave of peristalsis causing it to mix (This is the growling noise you can sometimes hear after you have eaten). This makes sure the acid mixes with the food extremely efficiently, the acid must reach as much of the surface area as quickly as possible. Once ready the food is now mostly a smooth thin liquid. (speed is essential, once the meat and other parts of the food start to digest many of its most useful substances and materials start to break down and become very short lived)

Once the food reaches the correct point of digestion, it is allowed through a sphincter in waves pushed by the stomach and into the duodenum and upper intestine. Another digestive juice is added here - the bile, which is an enzyme that helps break down and digest the fats (fat is very difficult to digest). The food liquid travels through the long narrow small intestine in separate sections, separated and squeezed along by moving waves of peristalsis. Here is the most crucial part of digestion, the nutrients and other parts of the food that are useful are absorbed through the wall of the small intestine and into the body.

In the body : A special blood supply carries the digested food substances into the liver where they go through a final cycle of filtering and processing, waste from this stream goes into the urine through the blood. The food is carried through the body mostly in the form of ??simple sugars?? If you don't eat too much most of it will be used immediately as fuel. This produces reaction products, of which some parts leave as uric acids, others get turned into bile and get used to digest tomorrows meal. (the chemical side is pretty complicated stuff)

In the bowel : The part of the liquid not absorbed in the small intestine continues through into the large intestine pushed along by more waves of peristalsis. This final part of the process absorbs the water out of the liquid in stages. The large intestine is quite short and the food moves through it more and more slowly as it is dried out. The large intestine squeezes and crushes down the paste into solid masses - and stores it until the bowls owner is ready to get rid of them. The rectum and anus are the final part of the bowel and the final sequence of the process is another wave of peristalsis along with a compression of the whole abdominal cavity. Once we are ready the anus is released, as the pressure rises the anus continues to hold its tension until a critical point is passed then it opens and releases the final material, as soon as the flow and pressure slows the critical point is passed again and the anus closes itself tight shut. The rectum pushes and squeezes the rest back up into the bowl in a reflex for the next go.

The digestion in the stomach takes from as little as 30 mins for light foods like fish or bread, through to 8 or 9 hours or more for a large heavy meal involving beef or heavy fats, a huge meal like Christmas can take almost 24 hours to fully digest. I believe the passage through the small intestine takes roughly 3 to 5 hours, and for the large its from 6 to 24 for normal processing. Digestive processes tend to slow and lag or even stop while the body is active or tense and accelerate when relaxed or warm or asleep. - If we look many of us tend to fall asleep (or at least get very tired) an hour or two after a large meal, this is because digestion takes a tremendous amount of energy.

The speed of digestion is to some extent a measure of metabolic health (hence a 'hearty' appetite). When we look at children they eat a great deal more than adults for their body size, (healthy) children have a more rapid digestion but also a faster metabolism and burn food more rapidly - they waste a lot of energy. This also makes them very active which is why adults often find them so tiring (actually growing takes a lot of energy as well) .

Why doesn't vomit taste exactly like the food you previously ate - i.e. if you were sick after eating lemon pie - why doesn't the vomit taste delicious like lemon pie?

When you vomit, you don't just vomit what you last ate, especially if you have not eaten recently. Vomit also includes various juices produced in your stomach, primarily for digestion. The components of this include hydrochloric acid and various digestive enzymes. Additionally, the food is almost immediately altered by the digestion process, starting with saliva that breaks down the starch in the pie crust, and the acid of the stomach which dissolves the proteins. This hydrochloric acid (and, less frequently, bile backed up through the duodenum) is the cause of the burning sensation.

The name of the passage through which food intake occurs?

The mouth, the throat and the oesophagus is the route through which food passes to the stomach.

Why can't you swallow a hammer?

1.Why an installed program in a PC not working after reboot 2.why the system does't shut down even the power optiuons are coorect?

1: Maybe it's not compatible with the OS *Cough Vista cough*

2: This happened to me when i replaced my power supply. The original one i brought home would not turn off so i took it back and got a diffrent one and everything has been fine ever since. So if you've recently replaced the power supply or recently built this computer maybe it's a faulty power supply.
