	Fight or Flight Response	All of the body's resources are allocated toward the immediate survival.
	The adrenal gland enlarges	The medulla secretes epinephrine The cortex secretes adrenal cortical hormones
Epinephrine increases the blood glucose level, fuel for muscles and brain, by mobilizing the glycogen stores in muscle and liver. increases blood pressure increases heart rate increases heart muscle contraction increases cardiac output dilates the pupil Adrenal Cortical Hormones Conserve energy and raw materials needed for the immediate survival Inhibit the body's self healing mechanisms such as the inflammatory response and the immune system Inhibit digestion and assimilation

Having stopped the peristaltic movements to pass feed along the digestive tract, it will now be easy for the resident bacterial flora in the absence of any immune response to proliferate.
