The sympathetic and parasympathetic systems are two branches of the autonomic nervous system (ANS), which controls involuntary actions like heart rate, digestion, and breathing.
*Sympathetic System:*
– Often called the “fight or flight” response
– Prepares the body for physical activity and stress
– Increases:
– Heart rate
– Blood pressure
– Respiration rate
– Glucose release from energy stores
– Decreases:
– Digestion
– Salivation
– Associated with the release of adrenaline (epinephrine) and noradrenaline (norepinephrine)
*Parasympathetic System:*
– Often called the “rest and digest” response
– Promotes relaxation and recovery
– Increases:
– Digestion
– Salivation
– Tear production
– Urination
– Decreases:
– Heart rate
– Blood pressure
– Respiration rate
– Associated with the release of acetylcholine
Both systems work together to maintain homeostasis, and an imbalance can lead to various health issues.
