sympathetic nervous system; endocrine system
Step-by-step explanation:
Charusheela is alone in her house and has just heard a loud sound outside her window. She normally does not get frightened, but tonight she is, and she is noticing her breathing increase and her pulse quicken. Both her sympathetic nervous system and endocrine system are working to respond to this potential crisis.
The sympathetic nervous system directs the body's rapid involuntary response to dangerous or stressful situations while The endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs.
