Blood pressure is the lateral pressure exerted on the wall of arteries by a flowing blood.
High blood pressure, also known as hypertension. Is a condition characterised by increased blood pressure to a abnormal level. This has to do with the lateral pressure exerted by a flowing blood on the wall of the arteries. This occur as a result of narrowing of the the blood vessels thereby causing an increase resistance to blood flow by the arteries.
While low blood pressure, also known as hypotension is a condition characterised by a decreased blood blood pressure. This occur as a result of widening of the blood vessels thereby causing a decrease resistance to blood by the arteries, thus a low blood pressure occurs.
