Digestion Facts: How Well You Know? Quiz
How well do you know about digestion? Do you think you can assimilate this quiz? Digestion is the breakdown of large insoluble food molecules into small soluble food molecules to be absorbed. In basic terms, digestion is how your body turns the food you eat into nutrients and uses it or energy. Taking this quiz will help you grasp facts about digestion.
Questions and Answers
- 1.
The fatty acids and glycerol are then absorbed into the blood stream via the villi of the_________
Explanation
The fatty acids and glycerol are absorbed into the bloodstream via the villi of the small intestine. The small intestine is responsible for the majority of nutrient absorption in the body. The villi are small finger-like projections that line the inner surface of the small intestine and increase its surface area, allowing for efficient absorption of nutrients. As the fatty acids and glycerol pass through the small intestine, they are taken up by the villi and transported into the bloodstream to be used for energy or stored for later use.Rate this question:

A high fiber diet will reduce damage to the?
- A.
Stomach
- B.
Heart
- C.
Colon
Correct Answer
C. ColonExplanation
A high fiber diet will reduce damage to the colon because fiber adds bulk to the stool and helps it move through the digestive system more easily. This reduces the time that waste spends in the colon, decreasing the risk of constipation, hemorrhoids, and diverticulosis. Additionally, fiber helps to maintain a healthy balance of bacteria in the colon, which is important for overall digestive health.Rate this question:

A low fibre diet along with dehydration and low activity levels, can lead to____________ disease.
Correct Answer
diverticular, diverticular diseaseExplanation
A low fibre diet, dehydration, and low activity levels can contribute to the development of diverticular disease. Diverticular disease refers to the formation of small pouches (diverticula) in the lining of the colon. When there is a lack of dietary fibre, the stool becomes harder and more difficult to pass, leading to increased pressure in the colon. Dehydration can further exacerbate this by causing the stool to become even harder. Low activity levels can also contribute to constipation and decreased bowel movements, increasing the risk of diverticular disease.Rate this question:

Dehydration occurs when we lose
- A.
1% fluid
- B.
3% fluid
- C.
2% fluid
Correct Answer
C. 2% fluidExplanation
Dehydration occurs when we lose 2% fluid because our body needs a certain amount of water to function properly. When we lose more than 2% of our body's fluid, it can lead to symptoms such as thirst, dry mouth, fatigue, and dizziness. It is important to stay hydrated by drinking enough water throughout the day to prevent dehydration and maintain optimal health.Rate this question:

Mastication occurs in the_________
Correct Answer
mouthExplanation
Mastication refers to the process of chewing food, which is primarily done in the mouth. The mouth contains teeth and the tongue, which work together to break down food into smaller pieces, making it easier to swallow and digest. Therefore, it is logical to conclude that mastication occurs in the mouth.Rate this question:

One function of the esophagus is?
- A.
Responsible for a large percentage of digestion
- B.
Delivering food to the stomach
- C.
Absorb water from the remains of food
Correct Answer
B. Delivering food to the stomachExplanation
The esophagus is responsible for delivering food to the stomach. It is a muscular tube that connects the throat to the stomach, allowing food to pass through and enter the digestive system. Once food is chewed and swallowed, it travels down the esophagus through a series of muscular contractions called peristalsis, which pushes the food towards the stomach. Therefore, the esophagus plays a crucial role in the process of delivering food from the mouth to the stomach for further digestion.Rate this question:

Pepsin is produced to break down protein in which section of the digestive system?
- A.
Stomach
- B.
Large intestine
- C.
Small intestine
Correct Answer
A. StomachExplanation
Pepsin is an enzyme that is produced in the stomach. Its main function is to break down proteins into smaller peptides, which can then be further digested in the small intestine. The stomach is the first major site of protein digestion in the digestive system, where pepsin is secreted by the gastric glands. Therefore, the correct answer is the stomach.Rate this question:
