Vedclass · Answer

(A) Adrenaline (also known as epinephrine) and Noradrenaline (also known as norepinephrine) are hormones secreted by the adrenal medulla in response to stress or emergency situations (often called the 'fight-or-flight' response).These hormones act on the cardiovascular system to increase heart rate,cardiac output,and blood pressure to prepare the body for immediate physical action.Since both adrenaline and noradrenaline have similar physiological effects on heart rate and blood pressure,the correct answer is that both $(B)$ and $(D)$ cause these effects.

Which hormone's secretion causes an increase in blood pressure and heart rate?
