Autonomous nervous system

The autonomic nervous system is a part of your nervous system that controls automatic functions like heartbeat, breathing, digestion, and blood pressure without you thinking about it. It helps the body respond to different situations—speeding up your heartbeat when you're excited or slowing digestion when you're stressed. It has two main parts: the sympathetic system, which prepares the body for fight or flight, and the parasympathetic system, which promotes relaxation and recovery. Overall, it works silently behind the scenes to keep your body balanced and functioning smoothly.
