Chapter 14, Problem 9a
Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
a. The parasympathetic nervous system generally decreases the secretion from digestive glands.
Verified step by step guidance1
Step 1: Understand the role of the parasympathetic nervous system. The parasympathetic nervous system is part of the autonomic nervous system and is responsible for 'rest and digest' functions, which include promoting digestion and glandular secretion.
Step 2: Analyze the statement provided. The statement claims that the parasympathetic nervous system decreases the secretion from digestive glands.
Step 3: Compare the statement to the known function of the parasympathetic nervous system. Since the parasympathetic nervous system typically increases secretion from digestive glands to aid in digestion, the statement appears to be false.
Step 4: Correct the false statement. The corrected statement should read: 'The parasympathetic nervous system generally increases the secretion from digestive glands.'
Step 5: Confirm the correction by reviewing the physiological effects of the parasympathetic nervous system, such as stimulation of salivary glands, gastric glands, and other digestive secretions.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Parasympathetic Nervous System
The parasympathetic nervous system is a component of the autonomic nervous system responsible for promoting 'rest and digest' functions. It generally conserves energy by slowing down the heart rate and increasing intestinal and gland activity, which enhances digestion and secretion from digestive glands.

Function of the Parasympathetic Nervous System
Digestive Gland Secretion
Digestive glands, including salivary glands, gastric glands, and pancreatic glands, secrete enzymes and other substances essential for digestion. The secretion of these glands is stimulated by the parasympathetic nervous system, which facilitates the breakdown of food and absorption of nutrients.

Autonomic Nervous System
The autonomic nervous system regulates involuntary bodily functions, including heart rate, digestion, and respiratory rate. It consists of the sympathetic and parasympathetic nervous systems, which have opposing effects; the sympathetic system prepares the body for 'fight or flight,' while the parasympathetic system promotes 'rest and digest' activities.
