Solution
The correct options are
B Noradrenaline
D Adrenaline
Noradrenaline interacts with beta receptors found on pacemaker cells in the heart. It stimulates the pacemaker cells, thereby increasing the rate at which they generate electrical charges. Each charge released from pacemaker cells cause the heart to contract. Noradrenaline increases heart rate initially but this effect is minimized by its effect on blood vessel.
Also, a rise in adrenaline increases heart rate, blood pressure, cholesterol, artery wall inflammation and blood clotting.
