A predator can be described as an organism that eats other organisms while the prey is the animal that is killed and eaten by the predator.

Answer:
Neurons in the parasympathetic division release neurotransmitters that act on receptors that slow heart rate
Stimulating the organs of digestion is a parasympathetic response
Parasympathetic nerves are associated with the cranial and sacral regions of the spinal cord, whereas sympathetic nerves are associated with the thoracic and lumbar regions
The sympathetic division of the PNS prepares the body for physical exertion in stressful situations.
Explanation:
The autonomic nervous system also called the vegetative nervous system is part of the peripheral nervous system which inervates smooth muscle and glands. Thus, it directly affects the function of internal organs and regulates functions such as the heart rate, digestion, respiratory rate, urination etc. This nervous system control is unconscious.
The autonomic nervous system is divided into: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.
Parasympathetic nervous system works when organism is at rest so it is known as system responsible for "rest and digest functions". On the other hand, sympathetic nervous system works at active and stressful situations and it is known as "fight and flight" system.
