Heart activity: Blood pressure is listed as a fraction: the higher number over the lower. The higher is a measurement (by blood pressure cuff and stethoscope) of the pressure of contracting heart pumping blood into the body and lungs, and the lower pressure is the baseline relaxed pressure in the arteries. Abnormalities of these values can indicate heart or blood vessel trouble which needs evaluation.

BP definition.: The blood pressure is the resistance to blood flow through the body. The higher number is the resistance when the heart pumps, and the lower number is the resistance when the heart relaxes and fills. High BP can lead to problems with the heart, kidneys, eyes, blood vessels and brain.
