The Digestive Process Quiz: Trivia!
.
Questions and Answers
- 1.
Where does digestion begin?
- A.
Stomach
- B.
All of the above
- C.
Mouth
- D.
Liver
Correct Answer
C. MouthExplanation
Digestion begins in the mouth. This is where food is broken down into smaller pieces through chewing and mixed with saliva, which contains enzymes that start the process of breaking down carbohydrates. The food then travels down the esophagus to the stomach, where further digestion occurs. The liver plays a role in digestion by producing bile, which helps in the breakdown of fats, but it does not mark the beginning of digestion. Therefore, the correct answer is the mouth.Rate this question:

What enzyme is found in the mouth?
- A.
Amylase
- B.
Pepsin
- C.
Bile
- D.
Glucouse
Correct Answer
A. AmylaseExplanation
Amylase is the correct answer because it is an enzyme that is found in the mouth. It is responsible for breaking down carbohydrates into smaller molecules, such as glucose, which can be easily absorbed by the body. Amylase is produced by the salivary glands and is released into the mouth during the process of chewing and swallowing food. It initiates the digestion of starches and helps in the breakdown of complex carbohydrates into simpler sugars.Rate this question:

Saliva is responsible for breaking down what?
- A.
Protein
- B.
Startch
- C.
Vitamins and minerals
- D.
Sugars
Correct Answer
B. StartchExplanation
Saliva contains an enzyme called amylase, which is responsible for breaking down starch into smaller molecules like glucose. This process is known as starch digestion. Therefore, the correct answer is starch.Rate this question:

When teeth break down food, it is an example of what?
- A.
Mechanical Digestion
- B.
Absorption
- C.
Chemical Digestion
- D.
All of the above
Correct Answer
A. Mechanical DigestionExplanation
When teeth break down food, it is an example of mechanical digestion because the process involves physically breaking down the food into smaller pieces. Mechanical digestion begins in the mouth with the chewing action of the teeth, which helps to increase the surface area of the food particles and prepares them for further digestion. This is different from chemical digestion, which involves the breakdown of food through the action of enzymes and other chemicals. Absorption, on the other hand, refers to the process by which nutrients are taken up by the body after digestion.Rate this question:

What transports food from the mouth to the stomach?
- A.
Saliva glands
- B.
Epilglotis
- C.
Bronchiles
- D.
Esophagus
Correct Answer
D. EsopHagusExplanation
The esophagus is a muscular tube that connects the mouth to the stomach. It transports food from the mouth to the stomach by using rhythmic contractions called peristalsis. The saliva glands produce saliva to help moisten and break down the food, but they do not transport it to the stomach. The epiglottis is a flap of tissue that prevents food from entering the windpipe during swallowing. Bronchiles is not a correct term and does not play a role in transporting food.Rate this question:
-
- 6.
What is the job of the epiglottis?
- A.
Keeps protecion from enzymes
- B.
Prevents food digestion down the gullet
- C.
Prevents food and liquids from going down your windpipe
- D.
Regulates enzyme control in your mouth
Correct Answer
C. Prevents food and liquids from going down your windpipeExplanation
The epiglottis is a flap of tissue located at the base of the tongue. Its main function is to prevent food and liquids from entering the windpipe, also known as the trachea. When we swallow, the epiglottis closes over the opening of the windpipe, directing the food and liquids towards the esophagus and down into the stomach. This prevents choking or aspiration of food into the lungs, ensuring that the respiratory system remains unobstructed.Rate this question:

Are the three main accessory organs stomach, liver, and gallbladder?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The three main accessory organs are actually the liver, pancreas, and gallbladder. The stomach is not considered an accessory organ, as it is a primary organ involved in the digestion process. The liver produces bile, the gallbladder stores and releases bile, and the pancreas produces digestive enzymes. Therefore, the correct answer is false.Rate this question:
-
- 8.
What enzyme is found in the stomach?
- A.
Amylase
- B.
Lipase
- C.
Stomach glands
- D.
Pepsin
Correct Answer
D. PepsinExplanation
Pepsin is the correct answer because it is an enzyme that is specifically found in the stomach. It is responsible for breaking down proteins into smaller peptides, aiding in the process of digestion. Amylase and lipase are enzymes that are found in the pancreas and are involved in the digestion of carbohydrates and fats, respectively. Stomach glands are not an enzyme but rather refer to the cells in the stomach that produce digestive juices, including pepsin.Rate this question:

The liver is responsible for producing what?
Correct Answer
BileExplanation
The liver is responsible for producing bile, a digestive fluid that helps break down fats in the small intestine. Bile is produced in the liver and stored in the gallbladder until it is needed for digestion. It contains bile salts, which emulsify fats and make them easier to digest and absorb. Bile also helps in the elimination of waste products, such as bilirubin, from the body. Overall, bile plays a crucial role in the digestion and absorption of fats in the body.Rate this question:

Is the large intestine most responsible for digestion?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The large intestine is not the most responsible for digestion. While it does play a role in the absorption of water and electrolytes, the majority of digestion occurs in the small intestine. The small intestine is where the breakdown of food into nutrients and the absorption of those nutrients into the bloodstream takes place. Therefore, the correct answer is false.Rate this question:
-
- 11.
What is the last part of the large intestine?
- A.
Behind
- B.
Anis
- C.
Rectum
- D.
Small intestine
Correct Answer
C. RectumExplanation
The last part of the large intestine is called the rectum. It is located at the end of the colon and serves as a temporary storage area for feces before they are eliminated from the body through the anus. The rectum plays a crucial role in the digestive process by allowing the body to control the timing of bowel movements.Rate this question:
-
- 12.
What is the last part of digestion tract?
Correct Answer
AnusExplanation
The last part of the digestive tract is the anus. It is the opening through which waste materials, such as feces, are eliminated from the body. The anus is located at the end of the rectum and is surrounded by muscles that help control the release of waste.Rate this question:
