Blood pressure is the force of blood against the artery walls. It rises during heartbeats and falls between heartbeats. There are always two pressures portrayed in blood pressure ranges, the systolic blood pressure and the diastolic blood pressure. Blood pressure ranges are typically written making use of the systolic blood pressure number before or above the diastolic blood pressure number, as an example 120/80 mmHg. The systolic blood pressure, the 120 as illustrated in the blood pressure chart, is the pressure reading as the heart pumps blood out of the ventricle into the veins. The diastolic blood pressure, the 80 as illustrated in the blood pressure chart, is the resting pressure, which is between beats when the pressure decreases before the next heart pumping action. High blood pressure is termed hypertension, low blood pressure is hypotension. If there’s no obvious reason for hypertension, which is commonly the case, it’s referred to as primary hypertension. Secondary hypertension, the term given to only 5 to 10% of cases, can be the result of a number of factors, amongst them kidney or heart disease and hardening of the arteries.
