Gastrointestinal Tract
Gastrointestinal (GI) tract refers to a tubular passage from mouth to anus that releases hormones to aid the digestion process. Extending about 8.3 meters, GI tract may be divided into three divisions: foregut, midgut, and hindgut.
603 Questions
Can gastric juice come out from nose?
I'm pretty sure it can. When/if you vomit, the juice that comes out that smells like vomit, chances are that it is gastric juice.
All vomit is is the contents of our stomach which includes gastric juices.
Why can severe vomiting tear the mucosa?
Simple--vomiting increases abdominal pressure and causes a sheering force as vomit pushes against sphincters that typically prevent backflow from the stomach into the esophagus. The stomach is a powerful muscle when aggravated (like by a toxin) and it will contract hard until it expels the problem material.
chocolate, grapes- That is the first answer someone gave. I don't think those are actually undigestible, but they are poisonous to dogs. Among other POISONS are garlic and xylitol. As for undigestible, dogs cannot digest rawhide, and I'm 99% sure they can't digest bones.
Turnover is analogous to usage of serotonin; it is the amount that is transmitted across the synapse and re-synthesized to replace the amount of serotonin used.
What would cause your stomach to feel like its on fire and fell nauseous?
I have a Hiatal Hernia and that is exactly what I feel. It took 2 months of hoping it would pass before I finally got an endoscopy and got it diagnosed. Part of my stomach has torn through my diaphragm and is up too high into my esophagus. It is not a super serious thing and it is very common but it does cause really bad heartburn as well as burning in my stomach from all of the acid build up. I also feel nauseous often if I eat something I shouldn't, which happens a lot. It could be that but there are about a million other things it could be too.

What are three stimuli that elicit a response from sensors in the wall of the tract organs?
Stretching of the organ by food in the lumen, osmolarity and PH of contents, and the presence of substances and end products of digestion
Is pain medication normally approved for the recovery time after a colonoscopy?
Colonoscopy is done under light sedation. You will be able to hear your doctor and move as he instructs, but you will not remember because the sedation causes a short period of amnesia. You will also not remember any discomfort you feel during the test. Within a very short time, the sedation wears off. The MOST you might feel after a colonoscopy is a little more gassy. But you will not have pain or aftereffects from the colonoscopy. Someone will need to drive you home as a precaution since you just had a med in your system.
Can women have a colonoscopy while having chlamydia?
chlamydia is bacterial infection by (std)colonoscopy possible,chlamydia is vaginal infection
What do you call extra skin on the edge of your butt hole?
Skin tags are a small flap of skin that grows above the level of surrounding skin, often as a tiny fingertip shape. Skin tags can appear anywhere on the body, but mostly on the trunk (chest, belly). Any skin tag can be removed, including from the eyelids.
Can a virtual colonoscopy be as effective as a regular colonoscopy?
Studies in late 2003 showed that virtual colonoscopy was as effective as colonoscopy for screening purposes and it offered the advantage of being less invasive and less risky. However, many physicians were unwilling to accept it
What is serotonin how it gets from food or plants?
Finding foods that increase serotonin levels is a bit more involved then looking at a nutritional summary. The point is to lean heavily on plant foods to reap the maximum amount of nutrients.
Gas, also called flatus or flatulence, is air in the intestine that is passed through the rectum. Air that is passed from the digestive tract through the mouth is called belching.
Alternative NamesFlatulence (flatus)
ConsiderationsGas is formed in the intestines as food is being digested. Gas can make you feel bloated, which may cause crampy or colicky abdominal pain.
Common CausesGas can be caused by any of the following:
- Antibiotics
- Eating foods that are difficult to digest, such as fiber. If you recently introduced fiber into your diet, having gas may be temporary. Give it a little time. Your body may adjust and stop producing gas.
- Eating foods that you cannot tolerate -- for example, if you have lactose intolerance and eat dairy products
- Irritable bowel syndrome -- a chronic form of stomach upset that gets worse with stress
- Malabsorption(when your body cannot absorb or digest a particular nutrient properly, often accompanied by diarrhea)
- Swallowing air while eating
- Avoid beans, cabbage, and carbonated beverages.
- Avoid gum chewing.
- Chew your food thoroughly.
- Eat more slowly.
- Relax while you eat.
- Walk for 10 - 15 minutes after eating.
Call your doctor if:
- You have other symptoms in addition to gas, like abdominal or rectal pain, heartburn, nausea, vomiting, diarrhea, constipation, or weight loss
- You have oily, foul-smelling, or bloody stools
Your doctor will perform a physical examination with special attention to your abdomen, and ask questions about your symptoms, such as:
- What is your diet like?
- Has it recently changed?
- What foods do you eat commonly?
- What foods have you eaten recently?
- Have you increased the fiber in your diet?
- How fast do you eat, chew, and swallow?
- Would you say that your gas is mild or severe?
- Does your gas seem to be related to eating milk products or other specific foods?
- What seems to make your gas better?
- What medications do you take?
- Do you have other symptoms like abdominal pain, diarrhea, early satiety(premature fullness after meals), bloating, or weight loss?
Diagnostic tests that may be performed include:
- Abdominal CT scan
- Abdominal ultrasound
- Barium enema x-ray
- Barium swallow x-ray
- Blood studies such as CBC or blood differential
- Sigmoidoscopy
- Upper endoscopy (EGD)

What is the condition resulting from the reflux of acidic gastric juice into the esophagus?
GERD, or GastroEsophageal Reflux Disorder is the condition. Results of GERD vary from mild to critical. Everyone has experienced GERD a few times -- as heartburn. And in these cases it's not critically dangerous. In chronic situations, however, the gastric acids can erode tissues of the esophagus and larynx resulting in what amounts to chemical burns of these areas. In extreme cases, ulcers can form, and bleeds in the esophagus can be nasty. Laryngitis, temporary or permanent can also be one result. If the gastric liquid is inhaled, however, real problems can occur. Pneumonitis, an pneumonia-like inflamation of lung tissue can result, which in turn can light off bronchial spasms and asthma-like symptoms that can lead to hypoxia and even death. Further, the damage to the lungs may cause an influx of serum into the lung as it heals, and in turn increases chances of pulmonary infection. Inhalation of gastric liquids is cause to call a doctor. Recovery time for this runs up to about 9 days, roughly.
What is the function of the Anal Canal?
The anal canal serves to transmit and lubricate stool as it passes externally from the rectum
How is secretion of pancreatic juice controlled?
Born Edson Arantes Do Nascimento (better known as Pelé) is known as a legend and the best soccer player to ever play the game. He was raised in a very poor family in Tres Coracos, Brazil and his parents, Dondinho and Celeste Nascimento called Edson "Dico," growing up.
He first learned the game of soccer from his father, Dondinho, who was a decent center forward until his career was halted by a fractured leg.
Pelé began playing soccer for a local minor-league club when he was a teenager. When he wasn't playing soccer he shined shoes for pennies. He was discovered at the age of 11 by one of the country's premier players, Waldemar de Brito. When Brito brought Pelé to Sao Paulo he declared to the disbelieving directors of the professional team in Santos, "This boy will be the greatest soccer player in the world."
He was right! Pelé's impact was immediate! On his first appearance for the team, against Corinthians F.C., he scored a goal right away. He was only 16.
Pelé went on to play in four World Cups with Brazil's National Team. At the 1958 World Cup in Sweden -- one he nearly missed because of a knee injury -- Pelé stunned the world scoring six goals, including two in the championship game to help Brazil win its first World Cup 5-2 over Sweden. He was only 17 years-old, but a legend was born.
An average-sized man, he was blessed with speed, great balance, tremendous vision, the ability to control the ball superbly, and the ability to shoot powerfully and accurately with either foot and with his head.
Four years later he played on Brazil's World Cup team at in the finals in Chile, but an injury suffered in the first game of the tournament prevented him from helping Brazil win its second title.
Wealthy European clubs offered massive fees to sign the young player, but the government of Brazil declared Pelé an official national treasure to prevent him from being transferred out of the country.
At the 1966 World Cup in England, Pelé was the victim of some brutal tackles from Bulgarian and Portuguese defenders and left the finals injured and in tears. But the best of Pelé was still to come.
At the 1970 finals in Mexico, the 29-year-old Pelé, led one of the greatest teams ever assembled to win Brazil's third World Cup. In the 4-1 title triumph over Italy, Pelé, scored a glorious goal. It was Brazil's 100th World Cup goal, and the one he remembers the most.
"I have a special feeling for that goal because I scored it with my head," he said. "My father was a soccer player and once scored five goals in a game, all with his head. That was one record I was never able to break."
Pelé's statistics are staggering. During his career he scored 1,280 goals in 1,360 games, second only to another Brazilian, Arthur Friedenreich, who recorded 1,329 goals. He scored an average of a goal in every international game he played--the equivalent of a baseball player's hitting a home run in every World Series game over 15 years.
At the club level he shattered records in Brazil. He scored 127 goals for Santos F.C. in 1959, 110 in 1961 and 101 goals in 1965, and led the club to two World Club championships.
Pelé also holds the world record for hat tricks (92) and the number of goals scored on the international level (97). His statistics are all the more amazing when compared to today's top players who can barely score more that 30 goals in a season.
He retired from the game in 1974, but came out of retirement the following year to play in the North American Soccer League for the New York Cosmos for just over two seasons. A reported 7-million-dollar contract for three years made him the highest paid soccer player of the North American Soccer League.
His appearance in the NASL gave the American League instant credibility and made millions of Americans aware of the sport, he dubbed the "beautiful game." He said he came out of retirement, not for the money, but to "make soccer truly popular in the United States."
During his career he played in 93 full internationals for Brazil and in all first class matches scored a remarkable 1,280 goals, second only to Artur Friedenreich, another Brazilian, who holds the world record with 1,329.
In many ways, Pelé was the complete athlete. With his skill and agility, he could have played in any position on the field, but he chose on wearing the number-10 shirt as an inside-left forward. He had great balance, which enabled him to dribble effortlessly around defenders, and his heading ability was remarkable.
On Oct. 1, 1977, Pelé's mission in the NASL ended. His last match, an exhibition game between the Cosmos and Santos, was sold out six weeks beforehand, covered by 650 journalists and broadcast in 38 nations.
Muhammad Ali embraced him in the locker room before the match and said, "Now there are two of the greatest." In a speech to dignitaries, celebrities and more than 75,000 fans, Pelé urged his audience to pay attention to the children of the world. At his request, the assemblage shouted, "Love! Love! Love!"
Then he went out and played the first half for the Cosmos -- scoring a goal on a rocket from 30 yards out -- and the second half for Santos.
On Pelé's retirement, J.B. Pinheiro, Brazil's ambassador to the U.N., said Pelé had "spent 22 years playing soccer, and in that time he has done more for goodwill and friendship than all of the ambassadors ever appointed."
In addition to his great accomplishments in soccer, he published several best-selling autobiographies, starred in several documentary and semi-documentary films, and composed numerous musical pieces, including the entire sound track for the film 'Pelé' (1977). He was the 1978 recipient of the International Peace Award, and in 1980 he was named athlete of the century.
In 1993, Pelé was inducted into the National Soccer Hall of Fame and is the former ambassador of sports in Brazil. He has also done extensive work for children's causes through UNICEF.
In 2000, Pelé was named second for the "Sportsman of the Century" award. The legendary Muhammad Ali got the honors.
What is the pH of gastric acid?
How does neurologic pain present in thoracic outlet syndrome?
Neurologic pain can occur on either sides of the forearm, upper back and upper chest, neck and ear. Pain is especially evident on the ring and small finger.
Mallory-Weiss syndrome is responsible for what percentage of all upper gastrointestinal bleeding?
Mallory-Weiss syndrome causes about 5% of all upper gastrointestinal bleeding.
What organ is not part of the gastrointestial tract?
All organs from all other body systems are not part of the gastrointestinal tract. As some examples, these are not involved with digestion: heart, lung, skin, reproductive organs.
Serotonin is a 'transmitter' chemical - it helps to pass nerve impulses from one nerve cell (neurone) to the next over the synapse (gap between two neurones).
It works like this;
1. When a nerve impulse travels the length of a neurone and reaches the end it must 'jump' the gap between one neurone and the next.
2. To do this, the impulse triggers the release of a transmitter chemical (such as serotonin) from the end of the neurone into the synapse.
3. These transmitter chemical molecules diffuse across the gap between the two neurones, and bind to special receptor molecules on the membrane (outer skin) of the next neurone.
4. When these transmitter chemicals bind to the right receptor molecules they trigger a new impulse carrying the same 'information' as the impulse in the previous neurone.
Serotonin is simply one of the many 'transmitter' chemicals.
Serotonin can also do the following:
1. It gives us self-confidence, a feeling of safety and security.
2. It causes us to feel sleepy.
3. It increases our appetites.
The part of the brain where it does each of these 3 things is a different part of the brain from the part where the other 2 things occur. Thus, for example, increasing serotonin in the part of the brain where self-confidence is will increase your self-confidence, but not your sleepiness. Unfortunately, we have no medications to increase only the serotonin in one part of the brain. This explains why medications to increase serotonin in the brain can also cause increased appetite and sleepiness.
Medications which increase serotonin in the brain (SSRI's such as citalopram, escitalopram, fluoxetine, paroxetine, and sertraline and SNRI's such as venlafaxine and duloxetine) give us more self-confidence, and a feeling of safety and security.
By the way, serotonin also exists in our gastrointestinal tracts. In this location, it stimulates digestion. This is why such medications can cause gastrointestinal upset. But they can also help constipation.
