Blood pressure is one of the critical and least understood aspects of our health. For that reason, I am reblogging this post I wrote five years ago. This is a perfect example of ‘what you don’t know can hurt you.’
Blood pressure is the force of the blood pushed against the the wall of the arteries, according to Nurse Practicioner Deborah Bergman, MS, RN, speaking to the Northwestern Memorial Healthy Transitions Program®.
Bergman explained that blood pressure depends on the strength of the heartbeat, thickness and volume of the blood, the elasticity of the artery walls and general health. It is the arterial pressure of the circulation. It is a dynamic process and fluctuates all day.
She said that blood pressure (BP) varies between a maximum (systolic) pressure – working phase. And the minimum (diastolic) pressure – the resting phase. Average blood pressure decreases as the blood moves away from the heart through the arteries. It drops most rapidly around the small arteries and continues to decrease as it moves through the capillaries and back to the heart through the veins.
