15. Endocrine System and Nervous System in Action!
Brain detects stress
Brain sends motor neuron to adrenal glands
Adrenal glands release adrenaline (epinephrine)
Adrenaline travels through blood to target cells
Causes increase in breathing, eyes dilate, heart pumps faster

16. Increase in heart rate, increase breathing, dilate eyes
adrenaline
