    Blood pressure is the force of blood pushing against the walls of arteries as the heart pumps blood around the body. Systolic pressure is the pressure when the heart contracts and pushes blood out and diastolic pressure is the pressure when the heart relaxes and fills with blood. In adults, the systolic pressure normally ranges between 80 and 120 and the...
