During stress, the sympathetic nervous system (activated when stimulated by exercise or experience pain, anger, fear) triggers the endocrine system.
The endocrine system releases hormones like cortisol and adrenaline, which affect metabolism and immune response.
Nervous system: the brain, spinal cord, and nerves (handles very short-term stress)
Endocrine system: glands, tissues, and cells that help control body functions (releases hormones, helps prepare the body to respond to stress, and handles both acute and chronic stress)
