What causes heart rate increase when blood pressure drops?

Taking the two formulas: Cardiac Output = Heart rate x Stroke Volume Blood Pressure = Cardiac Output x Peripheral Resistance When Blood pressure drops, either cardiac output (Heart rate or Stroke Volume) has to increase, or peripheral resistance (Aterioles Vasconstriction) has to increase When Blood pressure drops, this is detected by baroreceptors in the carotid bodies and arch of the aorta, these send signals to the cardio vascular centre within the Medulla, which sends signals back to the heart to increase the heart rate and force of contraction. The medulla also sends signals to arterioles to constrict and therefore raise blood pressure Hope this helps Colin.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
