Bile is produced by the
-
Liver
-
Pancreas
-
Gall Bladder
-
Stomach
Correct Answer
A. LiverExplanation
Bile is produced by the liver. The liver is responsible for producing bile, which is a greenish-yellow fluid that aids in the digestion and absorption of fats. Bile is then stored in the gallbladder and released into the small intestine when needed to break down fats. The pancreas also plays a role in digestion by producing digestive enzymes, but it does not produce bile. The stomach produces gastric juices, but not bile. Therefore, the correct answer is the liver.Rate this question:

Villi
Correct Answer
A. VilliExplanation
The finger-like structures lining the small intestine that absorb nutrients are called villi. These small projections increase the surface area of the intestine, allowing for more efficient absorption of nutrients into the bloodstream. The villi are covered in tiny microvilli, which further enhance the absorption process. Together, the villi and microvilli greatly increase the absorptive capacity of the small intestine, ensuring that nutrients from digested food are efficiently absorbed and utilized by the body.Rate this question:

Food moves through the digestive tract by wave-like muscle contractions which is called
-
Peristalsis
-
Digestion
-
Mucus
-
Stomach acid
Correct Answer
A. PeristalsisExplanation
Peristalsis is the wave-like muscle contractions that propel food through the digestive tract. These contractions occur in a coordinated manner, pushing food forward and allowing for efficient digestion and absorption of nutrients. Peristalsis starts in the esophagus and continues throughout the entire digestive system, ensuring that food moves along the tract and eventually reaches the stomach and intestines for further processing and absorption. It is an essential process in the digestive system that helps break down food and facilitate its movement through the body.Rate this question:

Stomach acid turning food into a soup-like substance is an example of
-
Mechanical digestion
-
Chemical digestion
-
Peristalsis
-
Enzyme activity
Correct Answer
A. Chemical digestionExplanation
Chemical digestion refers to the process of breaking down food into smaller molecules through the use of enzymes and other chemicals. In this case, stomach acid plays a crucial role in breaking down the food into a soup-like substance by providing the necessary acidic environment for the enzymes to work effectively. Therefore, stomach acid turning food into a soup-like substance is an example of chemical digestion.Rate this question:

Located where the small intestine joins the large intestine. It has no known purpose.
-
Gall bladder
-
Pancreas
-
Appendix
-
Stomach
Correct Answer
A. AppendixExplanation
The appendix is a small, finger-like pouch located at the junction of the small intestine and large intestine. Despite its small size, it has no known purpose in the human body. It is considered a vestigial organ, meaning it may have had a function in our evolutionary ancestors but is now considered non-functional. While it was previously believed to be useless, recent research suggests that the appendix may serve as a reservoir for beneficial bacteria, aiding in the recovery from infections and maintaining a healthy gut microbiome.Rate this question:

-
Stomach
-
Large Intestine
-
Small Intestine
-
Gall bladder
Correct Answer
A. Large IntestineExplanation
Water is removed and the materials that are not digested move into the Large Intestine. The Large Intestine is responsible for absorbing water from the remaining undigested food, as well as storing and eliminating waste material from the body. It plays a crucial role in the final stages of digestion and helps maintain the body's water balance.Rate this question:

-
Small intestine
-
Gall bladder
-
Large intestine
-
Pancreas
Correct Answer
A. Small intestineExplanation
The small intestine is responsible for absorbing nutrients from digested food into the bloodstream. It has tiny finger-like structures called villi that increase its surface area, allowing for more efficient absorption. These villi have a rich network of blood vessels that transport the absorbed nutrients to the rest of the body.Rate this question:

-
Esophagus
-
Large Intestine
-
Villi
-
Stomach
Correct Answer
A. StomachExplanation
The correct answer is the stomach. The stomach is a j-shaped sac that stores and further digests food. It secretes digestive enzymes and acids to break down the food into smaller particles, allowing for better absorption of nutrients. The stomach also contracts to mix the food with these digestive juices, forming a thick liquid called chyme.Rate this question:

____________ helps food glide through our digestive tract and it protects our organs from the digestive juices.
-
Mucus
-
Enzymes
-
Saliva
-
Tongue
Correct Answer
A. MucusExplanation
Mucus helps food glide through our digestive tract and protects our organs from the digestive juices. It acts as a lubricant, making it easier for food to pass through the esophagus, stomach, and intestines. Additionally, mucus forms a protective barrier that prevents the digestive enzymes from damaging the delicate tissues of our organs. Without mucus, the digestive process would be more difficult and potentially harmful to our bodies.Rate this question:

Digestion
Correct Answer
A. DigestionExplanation
Digestion is the process by which food is broken down into substances that can be used by the cells in the body. During digestion, food is mechanically and chemically broken down in the digestive system, primarily in the stomach and small intestine. This allows the nutrients from the food to be absorbed into the bloodstream and used by the body for energy, growth, and repair. Peristalsis is the process of muscle contractions that move food through the digestive tract, absorption is the process of nutrients being taken up by the body's cells, and elimination is the process of removing waste products from the body.Rate this question:

-
Elimination
-
Digestion
-
Absorbtion
-
Peristalsis
Correct Answer
A. AbsorbtionExplanation
Absorption is the process by which nutrients from the food we eat are taken into the bloodstream. After digestion breaks down the food into smaller molecules, these molecules are absorbed through the walls of the digestive system, specifically the small intestine. The nutrients then enter the bloodstream and are transported to the cells throughout the body to provide energy and support various bodily functions. Absorption is a crucial step in the digestive process as it allows the body to extract the necessary nutrients from food for growth, repair, and overall health.Rate this question:
