Final answer:
Nasogastric administration delivers drugs directly to the stomach. It involves a tube passing from the nose through the esophagus to the stomach. The small intestine is the main site for fat digestion, and fat-digesting enzymes are mostly produced by the pancreas.
Step-by-step explanation:
To which part of the body does nasogastric administration deliver a drug? The correct answer is c. the stomach. Nasogastric administration involves the use of a tube (nasogastric tube) that passes through the nose, down the esophagus, and into the stomach, allowing for the delivery of medication directly to the stomach.
Regarding digestion questions:
- The majority of fat digestion occurs in the c. small intestine, aided by enzymes from the pancreas and bile from the liver.
- The membrane that covers the stomach is none of those listed; the correct answer would be the peritoneum.
- Proteins are partially digested by the action of stomach enzyme pepsin, which breaks down proteins into smaller peptides.
- If the villi in the small intestine were damaged, it could lead to malabsorption of nutrients, resulting in nutritional deficiencies.
- The small intestine's MALT plays a crucial role in d. preventing bacteria from entering the bloodstream.
- The pancreas is the organ responsible for producing most fat-digesting enzymes.
The upper gastrointestinal (GI) tract includes the mouth, pharynx, esophagus, and stomach.
