The hormone responsible for dilating systemic arteries and increasing blood flow to the kidneys, thereby promoting urinary output, is atrial natriuretic peptide (ANP). ANP is released by the heart's atria in response to increased blood volume and pressure. It acts to reduce blood pressure by promoting vasodilation and enhancing sodium excretion, leading to increased urine production. This mechanism helps regulate fluid balance and blood pressure in the body.
Maybe it is spelled as " bradykinin ". The meaning is a peptide hormone that dilates peripheral blood vessels and increases capillary permeability.
As the afferent arteriole dilates it exposes the glomerulus to an increased blood pressure, closer and closer to that of the full systemic blood pressure. This increases GFR and Glomerular pressure. -6th Year Medical Student
Because it's an adrenalin - it increases heart rate, constricts blood vessels and dilates air passages
When released into bloodstream, epinephrine increases heart rate, constricts blood vessels, dilates air passages and participates in the fight-or-flight response of the sympathetic nervous system. Norephinephrine does the same and increases the brain's oxygen supply.

Adrenaline increases heart rate, dilates air passages in the lungs, increases blood flow to muscles, and triggers the release of glucose for energy. These effects help prepare the body for a "fight or flight" response to stress or danger.
Epinephrine, also known as adrenaline, plays a crucial role in the body's fight or flight response. It increases heart rate, constricts blood vessels, dilates air passages, and increases blood flow to muscles. This hormone helps prepare the body to respond to stress or danger.
Sodium nitroprusside is used in emergency to reduce the very high blood pressure. The drug dilates the arterial as well as venous system. So you get tachycardia and cardiac out put increases probably.
