AP PSYCHOLOGY

Detailed explanation-1: -Your sympathetic nervous system is best known for its role in responding to dangerous or stressful situations. In these situations, your sympathetic nervous system activates to speed up your heart rate, deliver more blood to areas of your body that need more oxygen or other responses to help your get out of danger.

Detailed explanation-2: -The sympathetic nervous system, also known as the “fight or flight” system, increases energy expenditure and inhibits digestion. The following changes take place on activation of the sympathetic nervous system: Heart rate and cardiac muscle contractility increase.

Detailed explanation-3: -The sympathetic nervous system mobilizes the body to respond to emergencies. The parasympathetic nervous system generally helps to conserve the body’s energy. It controls normal operations of the body such as digestion, blood pressure, and heart rate.

Detailed explanation-4: -The sympathetic nervous system mobilizes energy and resources during times of stress and arousal, while the parasympathetic nervous system conserves energy and resources during relaxed states, including sleep.

Detailed explanation-5: -The sympathetic system controls “fight-or-flight” responses. In other words, this system prepares the body for strenuous physical activity. The events that we would expect to occur within the body to allow this to happen do, in fact, occur. The parasympathetic system regulates “rest and digest” functions.
