Epinephrine causes vasoconstriction in blood vessels, leading to an increase in blood pressure and redirection of blood flow to vital organs such as the heart and brain. This response is part of the body's "fight or flight" reaction to stress or danger.
The effect of epinephrine mimics the effect of the sympathetic nervous system. Epinephrine is also known as adrenaline, and it activates the "fight or flight" responses in the body, such as increasing heart rate, dilating airways, and increasing blood flow to muscles.
Yes, epinephrine is converted to norepinephrine in the sympathetic nervous system by the enzyme phenylethanolamine N-methyltransferase (PNMT), which is found in the adrenal medulla. Norepinephrine acts as a neurotransmitter in the sympathetic nervous system.
norepinephrine/noradrenaline working in tandem with epinephrine/adrenaline
Epinephrine has an affinity for adrenergic receptors, particularly alpha and beta adrenergic receptors in the sympathetic nervous system.

The effect of epinephrine mimics the effect of the sympathetic nervous system. Epinephrine is also known as adrenaline, and it activates the "fight or flight" responses in the body, such as increasing heart rate, dilating airways, and increasing blood flow to muscles.
Epinephrine can cause vasodilation provided the level is low enough. If beta-2 recptors are activated (without the level of epinephrine being high enough to involve the significant numbers of alpha receptors), then the effect of epinephrine on the vascular smooth muscle be relaxation, thus, dilation. However, higher levels of epinephrine will activate alpha receptors which will cause vasoconstriction.

hoe long does epinephrine last in the system after injection?
Yes, epinephrine is converted to norepinephrine in the sympathetic nervous system by the enzyme phenylethanolamine N-methyltransferase (PNMT), which is found in the adrenal medulla. Norepinephrine acts as a neurotransmitter in the sympathetic nervous system.
The major difference between the vascular system of a human and a starfish is that humans have cardio vascular system and starfish have water vascular system.
