The pressure exerted by your blood flowing through your arteries is not constant but is dynamic, and constantly reflects what the heart is doing at a given moment.
When the heart is actively beating (an event called “systole”), it is ejecting blood out into the arteries. This dynamic ejection of blood into the arteries causes the pressure within the arteries to rise. The peak blood pressure reached during active cardiac contraction is called the systolic blood pressure.
Make sure to stop by the John Bell Health Center to have your blood pressure measured!
