This past fall, I took a Human Physiology class where we explored several different body systems and how the shape and size is equal to the function. During this course, we did a longitudinal data study, where over the course of three weeks, we conducted individual studies and took data of our blood pressure, heart rate, blood glucose, and urinalysis. We were tasked with finding variables that affected each test and understanding those processes.
Growing up with two doctors for parents and playing doctor instead of dress-up, I was a pro at using the blood pressure cuff to find my heart rate and blood pressure. The issue? I actually had no idea what any of it meant. Thankfully, my final paper can vouch for me that I did, in fact, learn what blood pressure is and the significance of the numbers:
Blood pressure is the pressure that circulating blood puts on blood vessels. In a blood pressure reading, there are two numbers: the first is your systolic blood pressure and the second is your diastolic blood pressure. Systolic blood pressure is the pressure of blood exerted on artery walls when your heart beats. Diastolic blood pressure is the pressure of blood exerted on artery walls in between heart beats. Overtime, high blood pressure can cause stiff arteries, making it harder for blood to pump and circulate throughout the body.
Normal systolic blood pressure: < 120 mmHg
High systolic blood pressure: >130 mmHg*
*There are different stages of high blood pressure, also called hypertension, and as the number goes up, it becomes more dangerous and necessary to consult a doctor.
Normal diastolic blood pressure: <80 mmHg
High diastolic blood pressure: >80 mmHg
