Blood pressure is the measurement of force against the walls of your arteries as your heart pumps blood through your body. The measurement is given in two different numbers: the top or higher number known as the systolic and the bottom or lower number known as the diastolic. The systolic is the highest pressure and the diastolic the lowest pressure during each heartbeat.
