Give the definition of parasympathetic nervous system?
SashulF [63]

Answer: Autonomic nervous system is made up of 3 divisions; Sympathetic nervous system, parasympathetic nervous system and sympathetic division. All these divisions are involuntary actions where parasympathetic is ultimately responsible for the "rest and digest" part of it. When the body is at rest the parasympathetic nervous system inhibits or lowers high energy requiring bodily functions.

This nervous system will lower any fight or flight response actions such as the release of epinephrine into the blood and enable digestion, urination and defeacation. When engaged in digestion you feel relaxed and at rest, this is solely due to the parasympathetic nevous system.

Olegator [25]

Answer:

The correct option is <u>C. The nervous system when the brain regulates the body's breathing and heart rate.</u>

Explanation:

The main function of the respiratory system is to exchange oxygen for carbon dioxide in the body.

The brain controls the rate at which the heart pumps blood. The pumping of the heart supplies oxygenated blood to other parts of the body. Hence, the rate at which heart pumps blood is very important to maintain homeostasis of the respiratory system.

The brain regulates the rate at which a person breathes. This rate is very important to breathe in the right amount of oxygen and to breathe out the right amount of carbon dioxide.
