what is the range of normal blood pressure? what do thhe two numbers represent?

119/79 or lower is normal blood pressure, the two numbers represent the systolic (top number) and diastolic (bottom number).

"When your heart beats, it contracts and pushes blood through the arteries to the rest of the body. This force creates pressure on the arteries. This is called systolic blood pressure."

"The diastolic blood pressure number or the bottom number indicates the pressure in the arteries when the heart rests between beats."
