Answer :

In the scary situation, the Adrenal Glands of the squirrel starts producing Adrenaline Hormone which helps us in responding to the 3 F situations - Fight, Flight and Fright. Release of Adrenaline in the bloodstream will cause an increase in breathing rate, blood pressure and the flow of blood towards the limbs (Hands and Feet) so that the muscle can contract at a faster speed, helping the squirrel to fight or run from the situation.

OR


Electrical impulses are transmitted through the neurons, whereas the chemical communication initiated by the hormones are passed directly into the bloodstream. The nervous system has its limitations as it cannot reach all the parts of the body, unlike the blood flow through which the chemical communication by the hormones can reach to all parts of the body.
