Answer:
Blood vessel diameter
Heart rate
Force of cardiac contraction
Explanation:
Blood vessel diameter:
Blood Vessel diameter affects peripheral resistance. The smaller the diameter, the higher the resistance to flow and the more the pressure rises
Heart rate:
heart rate and blood pressure can fall at the same time and can rise together at the same time like during exercise
Force of cardiac contraction:
Reduced cardiac contraction can help lower blood pressure to acceptable levels.
