Questions and Answers

2.

What enzymes for digestion are in the mouth?
- Lipids
- Pepsin
- Amylase
- None of the above
Correct Answer

A. Amylase

Explanation

Amylase is the correct answer because it is an enzyme that is present in the mouth and aids in the digestion of carbohydrates. It breaks down complex carbohydrates into simpler sugars, such as glucose, which can be easily absorbed by the body. Lipids are not digested in the mouth, and pepsin is an enzyme that is active in the stomach for protein digestion. Therefore, the correct answer is amylase.

3.

How many saliva do we produce in a day on an average?
- Half Litre
- One litre
- Two litres
- Two and a half litres
Correct Answer

A. Two litres

Explanation

On average, a person produces approximately two liters of saliva in a day. Saliva is produced by the salivary glands in the mouth and helps in the process of digestion by breaking down food and facilitating swallowing. It also helps in maintaining oral health by neutralizing acids and preventing tooth decay. The amount of saliva produced can vary from person to person and can be influenced by factors such as hydration levels, diet, and overall health.

Rate this question:
4.

What produces Saliva?
- The salivary glands
- The opening in the mouth
- Crown glands
- None of the above
Correct Answer

A. The salivary glands

Explanation

Saliva is produced by the salivary glands. These glands are located in the mouth and secrete saliva, which helps in the digestion process by moistening food and breaking it down chemically. The opening in the mouth is not responsible for producing saliva, and crown glands are not related to saliva production. Therefore, the correct answer is the salivary glands.

5.

What does the liver secretes?
- Bile
- Chyme
- Sweat
- Urine
Correct Answer

A. Bile

Explanation

The liver secretes bile, which is a digestive fluid that helps in the breakdown and absorption of fats in the small intestine. Bile is produced by the liver cells and stored in the gallbladder until it is needed for digestion. It contains bile salts, cholesterol, and waste products such as bilirubin. Bile plays a crucial role in emulsifying fats, making them easier to digest and absorb. It also helps in the elimination of waste products from the body.

Rate this question:
6.

What does the small intestine do?
- Absorb food
- Absorb nutrients
- Absorb water
- Produce Chyme
Correct Answer

A. Absorb nutrients

Explanation

The small intestine is responsible for absorbing nutrients from the food we eat. It is lined with tiny finger-like projections called villi, which increase the surface area and allow for better absorption. These villi absorb nutrients such as carbohydrates, proteins, fats, vitamins, and minerals into the bloodstream, where they are transported to the cells of the body for energy and other functions. The small intestine plays a crucial role in digestion and nutrient absorption, making the answer "Absorb nutrients" correct.

7.

What's the name of the semi-liquid created by the gastric acid?
- Chyme
- Luma
- Chowder
- Thyme
Correct Answer

A. Chyme

Explanation

Chyme is the correct answer because it is the semi-liquid substance that is created when gastric acid mixes with partially digested food in the stomach. It is then passed into the small intestine for further digestion and absorption of nutrients.

Rate this question:
8.

What does gastric mucosal secrete?
- Gastric acid
- Hydrochloride
- Pepsin
- Lipids
Correct Answer

A. Gastric acid

Explanation

The gastric mucosa secretes gastric acid, which is a strong acid composed mainly of hydrochloric acid. This acid helps in the digestion process by breaking down food and killing bacteria that may be present in the stomach. It also activates pepsin, an enzyme that helps in the breakdown of proteins. Lipids, on the other hand, are not directly secreted by the gastric mucosa.

Rate this question:
9.

What does the large intestine absorb?
- Food
- Water
- Nutrients
- Chyme
Correct Answer

A. Water

Explanation

The large intestine absorbs water. This is because the large intestine's main function is to absorb water and electrolytes from the remaining indigestible food matter, or chyme, that enters it from the small intestine. The absorption of water in the large intestine helps to solidify the waste material and form feces, while also preventing dehydration by reabsorbing water back into the body.

Rate this question:
10.

What are gastric mucosa openings called?
- Gastric glands
- Pits
- Gastric pits
- Opening
Correct Answer

A. Gastric pits

Explanation

Gastric pits are the openings in the gastric mucosa that lead to the gastric glands. These pits are lined with specialized cells that secrete various substances necessary for digestion, such as hydrochloric acid and enzymes. The gastric pits play a crucial role in the digestion process by allowing the secretions from the gastric glands to enter the stomach and mix with the food.
