Summarizing the fight or flight response article

In the human body, there are proteins that transfer signals throughout the body. Sometimes you feel the effects of them but dont realize what is actually happening. For example, when you get nervous, your body hair begins to stand up and you might even begin to sweat. All the signals that get transmitted and triggered throughout your body have different shapes, and as we learned before, different shapes mean different functions.They all do different things, transferring signals all over the body until it reaches its target. The muscle that holds your body hair and sweat glans tense up and it will pull your hair making it stand up and pushing the water out. When the signal transfers through the blood stream to the Bronchial, your lungs will expand instead of tense up in order for it you to breathe more. The contraction causes relaxation. Cells are one the most important things in our body, with cells, our bodies are allowed to function properly
