Respuesta :

Answer is I and II

Explanation:

  • Catecholamines are hormones made by your adrenal organs, which are situated on your kidneys.
  • Models incorporate dopamine; norepinephrine; and epinephrine (this used to be called adrenalin or adrenaline).  
  • Our adrenal organs send catecholamines into our blood when you're genuinely or sincerely focused.
  • They cause you to inhale quicker, raise your pulse, and send more blood to significant organs, similar to your cerebrum, heart, and kidneys.
