Which 2 processes do Digestion involve? (Separated by commas)
Explanation
Digestion involves two processes: physical digestion and chemical digestion. Physical digestion refers to the mechanical breakdown of food into smaller pieces, such as chewing and churning in the stomach. Chemical digestion, on the other hand, involves the breakdown of food through the action of enzymes and other chemicals, such as in the stomach and small intestine. Therefore, the correct answer includes both "Physical, Chemical" and "Physical Digestion, Chemical Digestion".Rate this question:

What causes a churning action in the stomach
- A.
Continual contractions and relaxations of the muscles in the stomach wall
- B.
Continual contractions muscles in the stomach wall
- C.
Continual relaxation muscles in the stomach wall
- D.
Continual contractions and breakdown of enzymes in the stomach wall
Correct Answer
A. Continual contractions and relaxations of the muscles in the stomach wallExplanation
The churning action in the stomach is caused by the continual contractions and relaxations of the muscles in the stomach wall. These contractions and relaxations help to mix the food and digestive juices together, breaking down the food into smaller particles and aiding in the digestion process.Rate this question:

Saliva is an enzyme, and does not have a pH Level
Correct Answer
C. PH 7Explanation
Saliva is a slightly acidic substance with a pH level of around 6.7 to 7.4. This means that it is close to neutral on the pH scale, which ranges from 0 to 14. A pH level of 7 indicates neutrality, neither acidic nor alkaline. Saliva helps in the digestion process by breaking down food, and its pH level plays a role in maintaining a suitable environment for enzymes to function properly.Rate this question:

- A.
Glucose
- B.
Fructose
- C.
Galactose
- D.
Sucrose
- E.
Lucose
Correct Answer(s)
A. Glucose
B. Fructose
C. GalactoseExplanation
The three end products of carbohydrate digestion are glucose, fructose, and galactose. These simple sugars are broken down from more complex carbohydrates during the process of digestion. Glucose is the most common and important simple sugar, as it is the primary source of energy for the body's cells. Fructose is commonly found in fruits and is also used as a sweetener in many processed foods. Galactose is less common and is typically found bound to glucose to form lactose, the sugar found in milk.Rate this question:

The second part of your small intestine is called ______?
Correct Answer(s)
jejunumExplanation
The second part of the small intestine is called the jejunum. It is located between the duodenum (the first part of the small intestine) and the ileum (the third part of the small intestine). The jejunum is responsible for the absorption of nutrients from digested food into the bloodstream. It has a larger diameter and more prominent blood vessels compared to the duodenum, allowing for increased absorption capacity.Rate this question:
