Anyone medically qualified this is for you.?
my husband is currently doing a first aid course and whenever the subject of vomiting is discussed they talk about carrots and sweetcorn we are wondering why does vomit always contain what looks like carrots and sweetcorn, what are the reason/causes for this. Sensible answers only please.
Answers:
As a nurse I have a lot of vomit and I can tell you that it does not all look it has carrots and or sweet corn in it. Someone is giving you wrong information.
Its stomach Lining,
i am not medically q'd but i seem to remember it has something to do with the way the enzimes in our stomach react to certain food groups. sorry i cant be more specific.
The carrots are actually stomach lining the sweetcorn is bile. Gross but true.
i know,you know,every body knows the point.
I dont know about the carrots, however sweet corn cannot be digested by the stomach, it even ends up in your poo!
"carrots" are stomach lining .it's a lining that the acidic content of stomach has eroded away during vomiting.
I know of no reason other than the possibility that the patient had eaten them. Corn is difficult for humans to digest because we lack an enzyme called cellulase, but I don't know about carrots.
I have taken those classes and, In my experience, those guys are probably goofing around.
I believe it is because the human digestive system can not break down the endosperum.(the outside shell of corn, ect.)
The carrot looking bit are actually food (mainly meat and high starch foods like bread,pasta and potatoes) that have been coloured orange by the bile in your stomach.
They are a combination of stomach lining and bile, also as the body cannot fully digest actual carrot and sweetcorn so they can actually be real carrot and sweetcorn chunks. I teach first aid in schools to kids as well as young people of an evening. When we are setting up scenes for training especially disaster preparedness we use chicken soup with carrot and sweetcorn for scenario work.
The instructors are acting unprofessional and stupid. All vomit does not look like carrots and corn. When was the last time you vomited? Did it look like carrots and corn? No, probally just whatever you have eaten in the past few hours.
Because the food that you eat will lost it color once it is in your stomach, and the intestine will digest the food to what looks like carrots and sweetcorn. so the one that is vomited looks like carrots and sweet corn. this color is the one that is being absorb to be classified as vitamins and minerals. so it is in the juice form. its like when you blend the food and beverages you consume the result is whats looks like carrots and sweetcorn .
Once the food that looks like carrots and sweetcorn is being absorb its contents and its nutrition's it will go to deeper intestine and will change color to what looks like sausages and peanut butter.
The vomiting act encompasses three types of outputs initiated by the medulla: Motor, Parasympathetic Nervous System (PNS) and Sympathetic Nervous System (SNS). Collectively, they are as follows:
Increased salivation to protect the enamel of teeth from stomach acids (excessive vomiting does lead to caries). This is part of the PNS output.
Retroperistalsis, starting from the middle of the small intestine, sweeping up the contents of the digestive tract into the stomach, through the relaxed pyloric sphincter.
A lowering of intrathoracic pressure (by inspiration against a closed glottis), coupled with an increase in abdominal pressure as the abdominal muscles contract, propels stomach contents into the esophagus without involvement of retroperistalsis. The lower esophageal sphincter relaxes. This is part of the motor output, and it is also important to note that the stomach itself does not contract in the process of vomiting.
Vomiting is ordinarily preceded by retching.
Vomiting also initiates a SNS response causing both sweating and increased heart rate.
The neurotransmitters that regulate vomiting are poorly understood, but inhibitors of dopamine, histamine and serotonin are all used to suppress vomiting, suggesting that these play a role in the initiation or maintenance of a vomiting cycle. Vasopressin and neurokinin may also participate.

Content
Since the stomach secretes acid, vomit contains a high concentration of hydronium ions and is thus strongly acidic. Recent food intake will be reflected in the gastric vomit.
The content of the vomitus (vomit) may be of medical interest. Fresh blood in the vomit is termed hematemesis ("blood vomiting"). Old blood bears resemblance to coffee grounds (as the iron in the blood is oxidized), and when this matter is identified the term "coffee ground vomiting" is used. Bile can enter the vomit during subsequent heaves due to duodenal contraction if the vomiting is severe. Fecal vomiting is often a consequence of intestinal obstruction, and is treated as a warning sign of this potentially serious problem ("signum mali ominis"); such vomiting is sometimes called "miserere".
If the vomiting reflex continues for an extended period of time with no appreciable vomitus, the condition is known as non-productive emesis or dry heaves, which can become painful and debilitating.

Complications of vomiting
[edit]
Aspiration of vomitus
Vomiting can be very dangereous if the gastric content gets into the respiratory tract. Under normal circumstances the gag reflex and coughing will prevent this to occur, however these protective reflexes are compromised in persons under narcotic influences such as alcohol or anesthesia. The individual may choke and asphyxiate or suffer an aspiration pneumonia.
[edit]
Dehydration and electrolyte imbalance
Prolonged and excessive vomiting will deplete the body of water (dehydration) and may alter the electrolyte status. The loss of acids leads to metabolic alkalosis (increased blood pH), and the electrolyte imbalance shows hypokalemia (potassium depletion) and hypochloremia (chlorine depletion). The hypokalemia is an indirect result of the kidney compensating for the loss of acid. With the loss of intake of food the individual will become cachectic.
It is quite common that when one person vomits, others nearby will become nauseated, particularly when smelling the vomit of others, often to the point of vomiting themselves. It is believed that this is an evolved trait among primates. Many primates in the wild will tend to browse for food in small groups. Should one member of the party react adversely to some ingested food it may be advantageous (in a survival sense) for other members of the party also to vomit. This tendency in human populations has been observed at drinking parties, where excessive consumption of alcoholic beverages may result in a number of party members vomiting nearly simultaneously, this being triggered by the initial vomiting of a single member of the party. This phenomenon has been touched on in popular culture: one notorious instance appears in the 1986 film Stand By Me, while in the computer game Theme Hospital, it is referred to as a 'vomit wave' and can spread through the hospital quickly.
There have also been documented cases of a single ill and vomiting individual inadvertently causing others to do so, when they are especially fearful of also becoming ill, through a form of mass hysteria.

Context
Most people try to contain their vomit by vomiting into a sink, toilet, or trash can, as both the act and the vomit itself are widely considered embarrassing; vomit is also difficult to clean up. On airplanes and boats, special bags are supplied for sick passengers to vomit into. Alternatively, a special disposable bag is available containing absorbent material that solidifies the vomit quickly, making it convenient and safe to keep (leakproof, puncture resistant, odorless) until there is an opportunity to dispose of it conveniently.
People who vomit chronically (e.g. as part of an eating disorder such as bulimia nervosa) may devise various ways to hide this abnormality.

In language
As with other physiological processes involving body wastes, vomiting has taboo aspects. This is shown by the large number of colourful euphemisms for vomiting. (see: toilet humour). Reference to vomiting is often made in speech (e.g. "it makes me sick", "I need a bucket") or by gesturing to signify being disgusted by someone or something.
Slang terms for the act of vomiting include: "hurling", "puking", "throwing up", "upchucking", "boking", "ralphing", "barfing", "chucking up" and "spewing".
everyone knows its stomach lining
