Digestion and Absorption can be use interchangeably
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Digestion and absorption cannot be used interchangeably because they are two distinct processes in the digestive system. Digestion refers to the breakdown of food into smaller molecules that can be absorbed by the body, while absorption is the process by which these smaller molecules are taken up by the cells of the digestive tract and transferred into the bloodstream. Although digestion and absorption are closely related and occur simultaneously, they are separate processes with different functions.Rate this question:

Which phase of digestion occurs ONLY in the small intestine BUT on the surface of the enterocytes?
- A.
Luminal
- B.
Gastric
- C.
Mucosal
- D.
Intracellular
Correct Answer
C. MucosalExplanation
Mucosal digestion occurs only in the small intestine but on the surface of the enterocytes. This phase involves the breakdown of food molecules into smaller nutrients that can be absorbed by the enterocytes and transported into the bloodstream. The small intestine has specialized structures called villi and microvilli that increase the surface area available for digestion and absorption. Enzymes secreted by the enterocytes break down complex molecules such as carbohydrates, proteins, and fats into simpler forms that can be easily absorbed. Therefore, the correct answer is "Mucosal."Rate this question:

The sympathetic and parasympathetic can influence and control the neuroendocrine system
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The sympathetic and parasympathetic nervous systems are responsible for regulating different bodily functions, such as heart rate, digestion, and stress response. While they do play a role in modulating the neuroendocrine system, they do not have direct control over it. The neuroendocrine system involves the interaction between the nervous and endocrine systems, where hormones are released into the bloodstream to regulate various physiological processes. Therefore, the statement that the sympathetic and parasympathetic can influence and control the neuroendocrine system is false.Rate this question:
