You ingest food and eventually, it comes out as feces. Any idea of what happens in-between? If you passed part I, you are ready for part II!
This quiz was expert written by Eugene Fenster. Eugene has a Ph.D. in Ecology and Evolutionary Biology and taught both general biology and nutrition. Several of his publications have appeared in peer-reviewed journals. He revises chapters, produces, edits, and proofreads materials for college textbooks. Most importantly he loves learning about biology. Learning and making connections among the disparate pieces of information he finds is one of his passions. Another passion is sharing and discussing this information with others.

Question 1
Which of the following is "easiest" to live without?
-
AEsophagus
-
BLarge intestine
-
CPancreas
-
DSmall intestine
Large intestine
The majority of all digestion and absorption occurs before the remains of the meal reaches the large intestine.
Question 2
Which of the following is most likely the cause of hemorrhoids?
-
ABeing on birth control pills.
-
BA high phytochemcial diet.
-
CA low fiber diet.
-
DA high protein diet.
A low fiber diet.
The less fiber the less solid feces have to push harder to defecate hemorrhoids.
Question 3
Diverticula in the colon are caused by _____.
-
Aa lack of dietary fiber
-
Ba H. pylori infection
-
Cover use of nonsteroidal anti-inflammatory drugs (NSAIDS) such as iburofen
-
Dexcessive coffee consumption
a lack of dietary fiber
Diverticula is a condition that develops pouching of the wall of the large intestine. This is caused by the large intestine working harder to push less solid fecal matter towards the anus.
Question 4
Hopefully, food/drinks that you consume will move from the mouth to the pharynx then to the _____.
-
Aliver
-
Btrachea
-
Cesophagus
-
Dstomach
esophagus
The epiglottis makes sure that food and fluid enter the esophagus rather than the trachea. From the esophagus, food and fluid move to the stomach.
Question 5
What is peristalsis?
-
AThe mixing and breaking apart of a mass of food as occurs in the small intestine.
-
BThe series of muscular contractions that begins in the esophagus and moves the contents of the digestive tract towards the rectum.
-
CThe detoxification of drugs as occurs in the liver.
-
DThe mechanical breakdown of food as occurs in the mouth.
The series of muscular contractions that begins in the esophagus and moves the contents of the digestive tract towards the rectum.
Peristalsis starts at the esophagus and ends with defecation.
Question 6
Which of these equations would best be associated with a digestive enzyme?
-
AFat + bile fat droplets
-
BPeptides + HCl protein
-
CGlucose + glucose maltose
-
DPeptides + H2O amino acids
Peptides + H2O amino acids
Digestion involves the breaking of chemical bonds.
Question 7
The secretion of saliva is stimulated by __________.
-
Athe sound of food only
-
Bthe smell, taste, and sound of food only
-
Cthe smell and taste of food only
-
Doral stimulation and the thought, sight, smell, taste, and sound of food
oral stimulation and the thought, sight, smell, taste, and sound of food
All of these are ways your body detects the presence of food and, as a result, prepares itself for the intake of food.
Question 8
What is halitosis?
-
AChronic heartburn
-
BChronic diarrhea
-
CChronic bad breath
-
DChronic constipation
Chronic bad breath
Halitosis may be a indication of serious health issues such as diabetes.
Question 9
The normal pH of the products of digestion that move from the stomach to the small intestine is _____.
-
A10-11
-
B5-6
-
C2-3
-
D18
2-3
This is not quite as acidic as the HCl secreted by the stomach. The acidity of the products of the action of the stomach (chyme) that moves to the small intestine is neutralized by, among other things, the bicarbonate that is produced by the pancreas and secreted into the small intestine.
Question 10
What name is given to a unit of swallowed food?
-
ALipo protein
-
BBolus
-
CChyme
-
DMicelle
Bolus
The tongue shapes chewed and partially digested food into a bolus that is then swallowed.
Question 11
HCl in the stomach _____.
-
Ais the major cause of ulcers
-
Bpromotes the absorption of water
-
Cpromotes the absorption of nutrients such as vitamin B-12, calcium, and iron
-
Dpromotes the absorption of alcohol
promotes the absorption of nutrients such as vitamin B-12, calcium, and iron
This is why a lack of stomach acidity increases the risk of certain nutrient deficiencies. In addition, stomach acidity can kill pathogenic bacteria that may enter our bodies along with food and drink.
Question 12
Bile plays a role in the digestive systems processing of _____.
-
Aminerals
-
Bfats
-
Cproteins
-
Dcarbohydrates
fats
Bile emulsifies fats. Emulsification occurs when large fat globules are broken up (not digested) into smaller fat globules. More, smaller fat globules increase the surface area available for the fats and faciltates digestion. Bile is also required for fat to be absorbed.
Question 13
What are villi?
-
Afinger-like projections that increase the surface area of the small intestine
-
Babnormal finger-like white blood cells
-
Cthe absorptive surface of the colon
-
Dthe bad guys in bad movies
finger-like projections that increase the surface area of the small intestine
Vili increases the surface area of the small intestine. This allows for the presence of more of the digestive enzymes that are attached to the surface of intestinal cells and also increases the surface area available for the absorption of nutrients.
Question 14
Constipation is associated with an increased risk of _____.
-
Acardivascular disease
-
Btype 2 diabetes
-
CParkinson's disease
-
Ddementia
cardivascular disease
One possible reason for this linkage is that straining to defecate raises blood pressure and increaased blood pressure increases cardiovascular risk.
Question 15
Oxalate-rich foods _____.
-
Apromotes tooth decay
-
Bincrease the risk of gallstones
-
Cincrease the risk of kidney stones
-
Dinhibit the absorption of vitamins
increase the risk of kidney stones
Most kidney stones are composed of calcium oxalate. One of the ways these stones can form is when there is an excessive amount of oxalate moving from the blood to the kidneys.
Question 16
Excessive calcium intake, as may occur from over-supplementation, may especially inhibit the absorption of _____.
-
Awater
-
Bvitamin K
-
Ciron
-
Dsulfur
iron
Calcium and iron compete to be absorbed by the small intestine. However, there is evidence that over the long term, calcium supplementation may not lead to an iron deficiency.
Question 17
Phosphorus absorption is promoted by _____.
-
Avitamin M
-
Bvitamin D
-
CVitamin A
-
Dvitamin E
vitamin D
Vitamin D promotes the absorption of both calcium and phosphorus. Under the influence of vitamin D, the kidneys promote the reabsorption of calcium and phosphorus, keeping these minerals in the body.
Question 18
Vitamins synthesized by microbes in the large intestine include _____.
-
AB28
-
BNo vitamins
-
CD
-
DK
K
Absorption of the vitamin K synthesized by intestinal microbes can meet 10% - 15% of the body's need for this vitamin.
Question 19
Periodontal disease does not include inflammation/degeneration of the _____.
-
Atonsils
-
Bthe bone that teeth fit into
-
Ccement that plays a role in holding your teeth in place
-
Dperiodontal ligaments
tonsils
Periodontal disease refers to diseases that have a direct impact on the structures that are responsible for keeping the teeth in place.
Question 20
What are the major causes of peptic ulcers?
-
AA stressful job
-
BA low fat diet and excessive carbohydrate intake
-
COverconsumption of coffee and tea
-
DOveruse of NSAIDs (such as ibuprofen), a H. pylori infection, and GERD
Overuse of NSAIDs (such as ibuprofen), a H. pylori infection, and GERD
There are three types of peptic ulcers: esophageal ulcers occurring in the esophagus, gastric ulcers occurring in the stomach, and duodenal ulcers occurring in the first portion of the small intestine. Esophageal ulcers are caused by the damage done to the esophagus as a result of the chronic reflux of stomach content (GERD)s. Anything that disrupts the mechanisms that protect the lining of the stomach or small intestines from the action of acids and enzymes may lead to the formation of an ulcer. Disruption of these protective mechanisms can be caused by infection with H. pylori or the overuse of NSAIDs. NSAIDs (non-steroidal anti-inflammatory drugs, include aspirin and ibuprofen. The mechanisms by which NSAIDs reduce inflammation is the same mechanism the disrupts an aspect of the mechanisms that protect the lining of the GI tract from acid-induced damage.
