Digestive System and Metabolism Trivia Questions

1. One of the foods that people think about when they think of gas is beans. What is it in the beans that causes gas when they are eaten?

From Quiz
I'm Forever Blowing Bubbles

Answer: A sugar called raffinose

Beans are a healthy food that contain a lot of protein and fibre. However, they also contain raffinose, which is a complex sugar that the body struggles to digest. After you eat them and the beans pass through the small intestine, they move into the large intestine where the body tries to digest that complex sugar. Bacteria break down the raffinose, producing hydrogen, carbon dioxide, and methane gas. These gases are then expelled through the rectum. Most beans will have this effect on the body, but there are some over-the-counter medications that have been helpful to some people in alleviating these "bubbles". If you are cooking with dry beans, soaking them for 8-12 hours and discarding the soaking water before cooking will also reduce the raffinose.

2. What is the medical term for a fart?

From Quiz Here Comes the Breeze

Answer: Flatus

A flatus is generally defined as intestinal and/or stomach gases passing through the anus. The scientific study of flatulence is called 'flatology'. Ructus is the scientific name for burping, coitus is the scientific term for sexual intercourse, and a meatus is a natural opening within the body.

3. Where does a normal person's digestive process first start?

From Quiz The Digestive System

Answer: Mouth

Unless you have a special condition that requires feeding through a tube, chances are that you eat through your mouth. As soon as the food goes into your mouth, salivary glands produce saliva to break the food down. This makes the food all wet and helps it to easily slide down the throat for extra digestion.

4. From top to bottom, the beginning of the alimentary canal is an area made from two parts, the oral cavity proper, and the vestibule. What is this region called where food enters just past the lips?

From Quiz Getting Down With The Human Alimentary Canal

Answer: mouth

The aperture between the lips is known as the oral orifice. Digestion actually begins before you place food into your mouth due to smelling of the food which allows the salivary glands to secrete digestive enzymes. The epiglottis functions to assist in swallowing and in breathing. The uvula assists in closing the nasopharynx during swallowing.

5. The small intestine consists of three parts - the duodenum, the jejunum and which other section?

From Quiz Down in the Bowels

Answer: Ileum

The duodenum is the first, and shortest, part of the small intestine, and receives partly digested food, called chyme, from the stomach via the pyloric sphincter. The mid part is the jejunum, with the ileum being the final part which is responsible for the final stages of digestion. Brachium refers to the upper arm, between the shoulder and elbow and the cerebrum is the major part of the brain. The sacrum is the bone at the base of the spine.

6. What is the name of the tube that starts from the mouth and ends at the anus?

From Quiz Digestive Distortion

Answer: Alimentary canal

The whole tubular structure of the digestive system is called the alimentary canal. It is about 9 metres long and is highly coiled, especially at the small intestine. It makes up the digestive system along with the digestive glands, salivary glands and teeth.

7. What is the the main source of fart gas?

From Quiz Must Thee Fart!

Answer: The air we swallow

Most of the air we swallow, especially the oxygen, is absorbed by the body before the gas enters the intestines. By the time the air reaches the large intestine, most of it is now nitrogen. Chemical reactions between stomach acid and intestinal fluids may produce carbon dioxide, which is also a component of air and a product of bacterial action.

8. Whilst we often digest sucrose - also known as table sugar - in many forms, it is glucose which we use for fuel. How is sucrose changed to glucose in the human body?

From Quiz Sugar, Fat, and Salt

Answer: Digested in the small intestine by enzymatic hydrolysis

In hydrolysis, a water molecule (H20) breaks the bond in sucrose between the glucose and the fructose. The connecting oxygen gains a H atom from the H2O molecule to complete glucose, leaving the OH- to complete the fructose. Sucrase, secreted in the small intestine, catalyses (speeds up) this reaction, which is otherwise quite slow. After the breakdown from disaccharide sucrose to monosaccharides glucose and fructose, they are absorbed into the bloodstream. Amylase IS in the mouth and involved in digestion of other carbohydrates, and if you chew bread for a while, you will notice it becomes sweet. However, it does not act on sucrose.

9. What is a colonoscopy?

From Quiz The Dreaded Colonoscopy

Answer: A procedure used to examine the colon

A colonoscopy is a procedure that is used to examine the colon or large intestine. It is done by inserting a "colonoscope" into the anus and then through the colon. A colonoscope is a small, lighted, flexible tube and fibre-optic camera.

10. What is the definition of a metabolic pathway?

From Quiz Aerobic Respiration

Answer: A series of reactions controlled by enzymes within a cell.

There are many metabolic pathways in the human body. Aerobic respiration only covers a couple. Others include the ornithine cycle, build up of muscle from protein, and the breakdown of lipids.

11. What can happen as a result of too little potassium (hypokalemia) in the blood?

From Quiz Your Electrolytes! Why Are They So Important?

Answer: respiratory muscle weakness, cramps, and heart rhythm disturbances

Potassium is an important positively charged element which is important in muscle function, both cardiac and striated muscle. The change in the "electrical potential" across muscle cell membranes causes these problems, and the cardiac symptoms and signs can range from palpitations through irregular heartbeats and even cardiac arrest.

12. Where, in the human body, is the liver?

From Quiz Is Life Worth Living? - It depends on the Liver

Answer: In the abdomen, towards the right hand side.

The liver is tucked just below the rib cage, towards the right hand side. The stomach is more towards the left.

13. The enzyme salivary amylase begins breaking down this type of food in the mouth.

From Quiz You've Eaten.... Now What?

Answer: Carbohydrates

Salivary amylase is secreted by the 3 pairs of salivary glands in the mouth. The broken down carbohydrates can then begin to be absorbed in the mouth. That is why cotton candy melts in your mouth.

14. Which tube does food flow down immediately before entering the cardiac sphincter?

From Quiz Anatomy 1001: Digestion

Answer: Esophagus

The trachea and laryngopharynx are tubes that air travels through during respiration.

15. What two organs in the body serve as a compensatory function to maintain acid base balance?

From Quiz Acid Base Imbalances

Answer: Kidneys & Lungs

The carbonic acid concentration is controlled by the amount of carbon dioxide excreted by the lungs. The bicarbonate concentration is controlled by the kidneys, which selectively retain or excrete bicarbonate in response to the body's needs.

16. What is the proper name (i.e. non-slang dictionary term) for a fart?

From Quiz The Fart Quiz

Answer: flatus

According to the Random House College Dictionary, a flatus is "an accumulation of gas in the stomach, intestines, or other body cavity." Literal interpretation of this definition would seem to indicate that a fart is a flatus only until it is released. However, the term flatus is commonly used as a term for gas that has been expelled. Gastralgia is a scientific name for "stomach ache". I made the other two words up.

17. What are the four functions of the tongue?

From Quiz What's in a mouth?

Answer: taste, speech, aiding chewing and swallowing

The bumps on the tongue that help you move food are called papillae.

18. What is the study of the gastrointestinal system?

From Quiz The Gastrointestinal System

Answer: gastroenterology

Gastroenterology incorporates the processes of digestion, absorption, and elimination.

19. Which cavity starts the GI system?

From Quiz Journey through the GI system

Answer: Oral & buccal & mouth&oropharynx

As obvious as it is, many people forget the mouth being part of the GI system.

20. In a healthy adult middle-aged man, 5' 11' tall and 82 kilograms in weight, what would be the approximate weight of his liver?

From Quiz It's Your Liver

Answer: 1.4 kilograms

In terms of weight, the liver is the largest organ in the human body and for the person described in this question, it would average 1.4 kilograms ( approximately 3 pounds). Thirty percent of the cardiac output in one minute passes through the liver. It receives both arterial and venous blood and is often referred to as the 'body's chemical factory'.

21. People who are lactose intolerant often produce "bubbles" when they eat dairy products. What causes this reaction to milk, cheese, and other dairy products?

From Quiz I'm Forever Blowing Bubbles

Answer: They don't produce enough lactase

Lactose is a sugar that is found in milk, cream, cheese, ice cream, and many other dairy products. In order to digest lactose, humans need an enzyme known as lactase that digests the sugars. If an individual does not produce enough lactase, they are not able to digest dairy products. Symptoms of lactose intolerance include bloating, nausea, diarrhea, stomach cramps, and gas. Many non-dairy products can be found in supermarkets that allow those who suffer from lactose intolerance to enjoy dairy-like food items without having to worry about developing "bubbles".

22. Certain foods, such as cabbage and beans, can cause flatulence. Why is this?

From Quiz Here Comes the Breeze

Answer: They contain lots of fibre and/or certain sugars

Certain sugars, such as raffinose (found in beans) or sorbitol (found in chewing gum and some fruits), can be broken down into hydrogen, methane and oxygen. Fructose, a sugar found in fruits, feeds the bacteria that live in your lower intestines and create gas by breaking down undigested fermentable particles.

23. How many muscles does a human tongue have?

From Quiz Catarrh Got Your Tongue

Answer: Eight

There are eight muscles in the human tongue: four are attached to a bone and four are not. The four attached to a bone, also known as extrinsic muscles, help move the tongue. The four intrinsic muscles, or those not attached to a bone, shape the tongue. It is those four muscles you use when you roll or fold your tongue.

24. After food moves further down the digestive tract, it enters a wide, fibromuscular tube that helps in chewing, as well as having a respiratory function. It is situated behind the larynx, and nasal and oral cavities. What is it called?

From Quiz Getting Down With The Human Alimentary Canal

Answer: pharynx

The pharynx has dual functions. One function is a digestive one in that it holds the food from the mouth to allow the muscles of the pharynx to help with chewing, while the other is a respiratory function where air from the nasal passages empties into the nasopharynx. The oropharynx is the area directly behind the mouth. Since the nasopharynx has a respiratory function, food shouldn't be going in that direction anyway.

25. 'I should have shut my mouth, things headed south As the words slipped off my tongue, they sounded dumb.' How many muscles are there in a human tongue?

From Quiz Slippery When Wet

Answer: 8

Contrary to popular belief, the tongue isn't just one long muscle! It's actually made up of eight different muscles. Half of these muscles are intrinsic, and the other half are extrinsic. The four intrinsic muscles enable the tongue to expand and contract, and play a part in speech and swallowing food. The four extrinsic muscles are attached to the jawbone and enable the tongue to move up and down, or from side to side. (Lyrics from 'Misunderstood', from the album 'Bounce'.)

26. What is another name for the food pipe?

From Quiz Digestive Distortion

Answer: Oesophagus

Oesophagus is the name given to the food pipe, which starts from the throat alongside the trachea, or wind pipe. It is the only part of the digestive system other than the large intestine which does not produce any enzymes.

27. On average, how much gas a day does one person produce?

From Quiz Must Thee Fart!

Answer: Half a litre

14 farts are made on a daily basis by one average person. However, this depends on what you eat as well (eggs!).

28. One of the important functions of the liver is the production of an enzyme that aids in the digestion of fats. What is this enzyme called?

From Quiz Liver Let Die

Answer: bile

Hydrochloric acid, pepsin and mucin are components of the gastric juice, which is secreted by the stomach to regulate digestion. Bile is produced and secreted by the liver, and it is administered through the gall bladder to aid in the digestion of fats.

29. What is the purpose of a colonoscopy?

From Quiz The Dreaded Colonoscopy

Answer: To investigate various diseases of the colon

A colonoscopy is used to investigate different diseases of the colon, such as inflammatory bowel disease, diverticular disease, and of course colorectal cancer. Although it isn't a fun thing to have done, it is very important in detecting early cancer. Colorectal cancer is not rare and is one of the leading causes of cancer deaths.

30. What is the name of the first enzyme involved in glycolysis in the presence of glucose?

From Quiz Aerobic Respiration

Answer: Hexokinase.

Glucose is phoshorylased by the enzyme hexonkinase (named as a result of glucose being a six carbon sugar).
