What are the two subdivisions of the autonomous nervous system? what is the function of each subdivision

The autonomous division of the nervous system includes the sympathetic nervous system and the parasympathetic. Activation of the former prepares the body for a regime of vigorous activity: the heartbeat becomes more frequent, the bronchi expand so that the lungs receive more oxygen. Blood from the digestive system rushes to the skeletal muscles. Under the influence of the parasympathetic nervous system, the body comes to a state of calmness and tranquility: the pulse slows down, digestion processes begin to actively occur, the body stores energy.
