Adrenaline has different effects on the arteries of the gut and skeleton muscles because it binds to different types of receptors in these areas. In the gut, adrenaline binds to alpha receptors, causing constriction of the arteries and reducing blood flow. In contrast, in the skeletal muscles, adrenaline binds to beta receptors, causing dilation of the arteries and increasing blood flow. This differential effect is due to the different types and distribution of receptors in these areas.
