1. The mass of food chewed and moistened in the mouth is called:

Explanation

The correct answer is bolus. Bolus refers to the mass of food that has been chewed and moistened in the mouth before it is swallowed. It is a cohesive mass that is formed by the tongue and saliva, making it easier to swallow and digest. Chyme, on the other hand, is the semi-fluid mixture of partially digested food and digestive juices that is formed in the stomach. Lysozymes are enzymes found in saliva that help break down bacteria, and intrinsic factor is a protein necessary for the absorption of vitamin B12 in the small intestine.

2. What are the three sections of the small intestine?

Explanation

The small intestine is divided into three sections: the ileum, duodenum, and jejunum. The ileum is the final part of the small intestine, where most of the nutrients are absorbed into the bloodstream. The duodenum is the first part of the small intestine, where the partially digested food from the stomach mixes with digestive enzymes from the pancreas and bile from the liver. The jejunum is the middle part of the small intestine, where further absorption of nutrients occurs. The other options, cecum and colon, are part of the large intestine and not the small intestine.

Submit
3. Chyme is slowly released through the ____________to the small intestine. 

Explanation

The correct answer is the Pyloric Sphincter. The pyloric sphincter is a ring of smooth muscle located between the stomach and the small intestine. Its main function is to regulate the flow of chyme from the stomach into the small intestine. It opens and closes to allow small amounts of chyme to pass through, ensuring that digestion and absorption can occur efficiently.

Submit
4. What connects the small intestine to the large intestine? 

Explanation

The ileocecal valve connects the small intestine to the large intestine. It is a one-way valve that prevents the backflow of fecal matter from the large intestine into the small intestine. This valve regulates the passage of digested food, allowing it to move from the small intestine into the large intestine for further absorption of water and electrolytes before elimination. The cardiac sphincter is located between the esophagus and the stomach, the stomach is a separate organ involved in digestion, and the colon is the final portion of the large intestine.

Submit
5. Protein to absorb vitamin B12 is called 

Explanation

Intrinsic factor is a protein that is required for the absorption of vitamin B12 in the small intestine. It is produced by the parietal cells in the stomach lining and binds to vitamin B12, protecting it from degradation by stomach acid. Intrinsic factor then carries vitamin B12 to the ileum, where it is absorbed into the bloodstream. Without intrinsic factor, vitamin B12 cannot be efficiently absorbed and can lead to a deficiency.

Submit
6. The semi-solid product of mechanical and chemical digestion in the _________ is called _____.

Explanation

Partially digested in the stomach and released into the duodenum.

Submit
7. Peristalsis (muscular contractions) moves food through the _______ 

Explanation

Peristalsis is the process of muscular contractions that helps in moving food through the gastrointestinal (GI) tract. The term "GI Tract" refers to the entire digestive system, including the stomach, small intestine, and large intestine. The variations in capitalization and abbreviation (gi tract and G.I. Tract) are acceptable and still refer to the same concept.

Submit
8. Most of the _________ and _________ take place in the small intestine. 

Explanation

The question is asking for the processes that occur in the small intestine. The small intestine is responsible for the digestion and absorption of nutrients. Digestion refers to the breakdown of food into smaller molecules, while absorption refers to the uptake of these molecules into the bloodstream. Therefore, most of the digestion and absorption processes take place in the small intestine.

Submit
9. This occurs in the Cephalic phase of digestion:

Explanation

During the cephalic phase of digestion, the nervous system is stimulated at the first thought of food, which triggers the release of digestive juices by the salivary glands. This is followed by the secretion of saliva and the churning of the stomach in response to the thought of food. Hunger and appetite also play a role in preparing the gastrointestinal tract for digestion.
