Introduction:
What is Blood Pressure? Blood Pressure can be defined as the force per unit area exerted on a vessel wall by the contained blood in the heart, and is measured by millimeters of mercury (mm Hg) (Marieb, 703). Each time the heart beats (which is about 60-70 times a minute at rest); it pumps out blood into the arteries. There are two types of pressure recorded that can determine your blood pressure. 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.  Usually they are written one above or before the other, such as 120/80 mmHg. The top number is the systolic and the bottom the diastolic. When the two measurements are written down, the systolic pressure is the first or top number, and the diastolic pressure is the second or bottom number (for example, 120/80). If your blood pressure is 120/80, you say that it is "120 over 80." Materials & Methods:

For this experiment you will need to have adequate space for your subject to move around, as well as something they can sit and recline on comfortably. You will also need: * Sphygmomanometer (Blood Pressure Cuff)

* Stethoscope
* Alcohol Swabs
* Stop Watch
First, have your subject s

Results:
When my subject (Female, 25) arrived, I recorded her initial blood pressure when she first came in. I recorded it twice so I could get a more accurate reading: | Trial 1:| Trail 2:|
Systolic Pressure:| 122| 121|
Diastolic Pressure:| 80| 80|

I then recorded her initial pulse pressures, which is the difference between systolic and diastolic pressure: | Trail 1:| Trail 2:|
Pulse Pressure:| 42| 41|

After I got her initial pressure, I then recorded the different variations between being in motion and at rest: Position:| Blood Pressure:| Pulse Pressure:|
Sitting Quietly| 122/80| 42|
Reclining...
