Blood pressure (B.P)is vital to life. Without the pressure that forces our blood to flow around the circulatory system, no oxygen or nutrients would be delivered through our arteries to the tissues and organs. It is the force that moves blood through our circulatory system. It is an important force because oxygen and nutrients would not be pushed around our circulatory system to nourish tissues and organs without B.P. It is also vital because it delivers white blood cells and antibodies for immunity, and hormones such as insulin.
Blood itself carries a number of other properties, including its temperature. It also carries one of our defenses against tissue damage, the clotting platelets that prevent blood loss following injury. But what exactly is it that causes blood to exert a pressure in our arteries? Part of the answer is simple – the heart creates B.P by forcing out blood when it contracts with every heartbeat. It cannot be created solely by the pumping heart.
Every individual should maintain a normal B.P from 90 – 120 / 60 – 80 mm Hg. B.P is given by two numbers, with one above or before the other – 120/80.120 – This is called systolic pressure and 80 – This is called diastolic pressure.
Types of B.P
- Systolic Blood Pressure: The normal range of systolic B.P should be 90 – 120 mm Hg.
- Diastolic B.P: The normal range of diastolic B.P should be 60 – 80 mm Hg.
Symptoms of Blood Pressure
- Increased thirst.
- Vision problems.
- Lack of concentration.
