What is the High Blood Pressure?

Hyphothesis

I think if we drink Coca Cola our blood pressure will increase.I think a healthy adult person need to have 120mmHg and if it have more than 120 mmHg it considered as High Blood Pressure. And also if a person have lower than 80 mmHg it considered low blood pressure.

What is blood pressure?

Blood is carried from the heart to all parts of your body in vessels called arteries. Blood pressure is the force of the blood pushing against the walls of the arteries. Each time the heart beats, it pumps out blood into the arteries. Your blood pressure is at its highest when the heart beats, pumping the blood. This is called systolic pressure. When the heart is at rest, between beats, your blood pressure falls. This is the diastolic pressure. Blood pressure changes during the day. It is lowest as you sleep and rises when you get up. It also can rise when you are excited, nervous, or active.
