Accessory organs of the digestive system include the following except
-
Liver
-
Pancreas
-
Stomach
-
Teeth
Correct Answer
A. StomachExplanation
The stomach is not considered an accessory organ of the digestive system because it is a primary organ involved in the process of digestion. The accessory organs, on the other hand, play a supporting role in digestion. The liver produces bile, which helps in the breakdown and absorption of fats. The pancreas produces digestive enzymes that aid in the breakdown of carbohydrates, proteins, and fats. Teeth, although not commonly thought of as organs, are essential for the mechanical breakdown of food through chewing.Rate this question:

Bile plays an important role in the digestion of __________.
-
Carbohydrates
-
Lipids
-
Nucleic acids
-
Proteins
Correct Answer
A. LipidsExplanation
Bile plays an important role in the digestion of lipids. Bile is produced by the liver and stored in the gallbladder. It is released into the small intestine during digestion to aid in the breakdown and absorption of dietary fats. Bile emulsifies the large fat molecules into smaller droplets, increasing their surface area and making it easier for enzymes called lipases to break them down into fatty acids and glycerol. This allows for better absorption of lipids in the intestines. Therefore, the correct answer is lipids.Rate this question:

Type of digestive system in which there is only a single opening for the ingestion of food
-
Single digestive system
-
Complete digestive system
-
Multiple digestive system
-
Incomplete digestive system
Correct Answer
A. Incomplete digestive systemExplanation
An incomplete digestive system refers to a type of digestive system in which there is only a single opening for the ingestion of food. In this system, food enters and exits through the same opening, which is usually the mouth. This type of digestive system is found in certain organisms such as jellyfish and flatworms, where digestion occurs in a simple cavity with no specialized organs or structures. The food is broken down and absorbed directly into the body cells without passing through a dedicated digestive tract.Rate this question:

-
Ruminant digestive system
-
Pseudo-ruminant digestive system
Correct Answer
A. Avian digestive systemExplanation
The avian digestive system refers to the digestive system found in birds. It is different from other digestive systems mentioned in the options because birds have a unique anatomy and physiology that allows them to efficiently digest their food. Birds have a crop, which is a specialized pouch where food is stored and softened before entering the stomach. They also have a gizzard, a muscular organ that helps grind food since birds do not have teeth. The avian digestive system is adapted for the consumption of grains and seeds, as well as insects and small animals.Rate this question:

-
Monogastric digestive system
-
Ruminant digestive system
-
Pseudo-ruminant digestive system
Correct Answer
A. Ruminant digestive systemExplanation
The ruminant digestive system is characterized by a large stomach divided into four compartments, namely the rumen, reticulum, omasum, and abomasum. This type of digestive system is found in cattle, sheep, and goats. Ruminants have a unique ability to ferment plant material in their rumen, which allows them to extract nutrients from cellulose. The fermentation process is facilitated by microorganisms present in the rumen. The other options, avian digestive system, monogastric digestive system, and pseudo-ruminant digestive system, do not match the description given in the question.Rate this question:

Ulcer is caused by bacterial infections or adverse side effects of medication that damages __________.
-
Salivary glands
-
Lining of the stomach
-
Muscles in the intestines
-
Esophagus
Correct Answer
A. Lining of the stomachExplanation
Ulcers are caused by bacterial infections or adverse side effects of medication that damage the lining of the stomach. The lining of the stomach is made up of a layer of cells that protect the stomach from the acid and digestive enzymes it produces. When this lining is damaged, it can lead to the formation of ulcers. Bacterial infections, such as Helicobacter pylori, can weaken the lining and make it more susceptible to damage. Additionally, certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), can also cause damage to the stomach lining and increase the risk of developing ulcers.Rate this question:
