How does the hypothalamus of the brain and ANS allow us to fight or flee in a stressful situation?

the "Fight or Flight" response is caused when the hypothalamus dumps the hormone adrenalin into the blood stream. Adrenalin causes the heart to beat faster, and allows animals, including humans, to perform extraordinary feats.
ANS (Autonomic Nervous System) is all the processes that happen in the body without having to think about it. Heart rate, breathing (though we can override autonomic breathing) and many other functions help us when adrenalin is added to the blood stream by speeding up and allowing "burst strength"
This is a fear response our bodies automatically undergo when we feel threatened, or in danger.
This response is also what skydivers, cliff jumpers, and other extreme sports participants are looking for. The sudden rush of adrenalin is kinda like a drug high.

Additionally, the hypothalamus contains blood vessels that supply nutrients and oxygen to the tissue, allowing it to function properly.
Is hypothalamus responsible for consciousness?
The hypothalamus is not directly responsible for consciousness. It plays a key role in regulating basic survival functions like hunger, thirst, body temperature, and hormone release.
