blood pressure for men

Blood pressure is a measure of the force of blood against the walls of your arteries (or blood vessels) as blood flows through your body. Blood pressure is reported as two numbers. The first or top number is the systolic pressure—the pressure of the blood in the vessels as the heart beats. The second or bottom number is the diastolic pressure—the pressure in the vessels as the heart relaxes between beats. Blood pressure is measured in millimeters of mercury (mm Hg), reflecting how much the pressure in your arteries would raise a column of mercury. A blood pressure of 120 mm Hg systolic and 80 mm Hg diastolic is written 120/80 (“120 over 80″).
