The air pressure inside a human body is roughly equivalent to the pressure of the atmosphere. Normal air pressure is about 13.7 pounds per square inch at sea level.
Blood pressure is the force of blood moving through your arteries, and is measured with twonumbers. The first, or top number, is your pressure when your heart beats, called the systolic pressure. The second, or bottom number, measures the force of blood in your arteries while your heart is relaxed (filling with blood between beats). This is called the diastolic pressure. Blood pressure usually varies throughout the day. For adults, a blood pressure reading of lower than 120/80 is considered normal.
