“What is blood pressure?”

When you go for a medical checkup, you will often hear a lot of talk about your “blood pressure”. But what exactly is this phenomena? Well, believe it or not, blood pressure is  actually a very simple concept. Your body is able to maintain it’s operations because the heart pumps blood (which carries oxygen) to all of it’s vital systems. This pumping motion causes blood to be pushed against the walls of your blood vessels, and we can quantify this force as blood pressure. Your blood pressure is usually measured in “millimeters of mercury” (or mmHg), and is given two values (for example, a stable blood pressure is considered to be 120/80 mmHg). But why on Earth will your blood pressure be given two values? Well, let’s think about it. When your heart pumps blood, it does not do so in a constant fashion. Instead, it acts like a piston, with a force changing in a beating nature. So your blood pressure will be the highest at the peak force (termed the systolic blood pressure), and lowest at the bottom (termed the diastolic blood pressure). The higher your blood pressure is, the higher you will have a risk of developing heart heart problems. For example, someone with a blood pressure reading of 135/85 mmHg is twice as likely to receive a heart attack as someone with a blood pressure of 115/75
