system is composed of blood vessels‚ blood‚ and the heart. This allows the system to play an important role in the moving of both nutrients and wastes in and out of the blood to maintain an overall homeostasis within the body. The previously completed experiments each had the objective of understanding how various factors may have an influence on blood flow rate. These factors include the effect of blood vessel radius‚ the effect of blood viscosity‚ as well as the effect of blood vessel length‚ and

Arterial blood pressure is "normal" when the systolic pressure is 90-119 mmHg and the diastolic pressure is 60-79 mmHg. When the arterial pressure is ≥120/80 mmHg‚ a person is considering being hypertensive [1-3]. According to U.S. national guidelines (JNC 7 Report and JNC 8 Report)‚ the following represents different stages of hypertension: Classification Systolic (mmHg) Diastolic (mmHg) Normal <120 <80 Prehypertension 120-139 80-89 Stage 1 140-159 90-99 Stage 2 >160 >100 Treatment of Hypertension

Effect of Arousal on the Heart Rate and Blood Pressure of Adolescent Males Wyatt Griffith and Michaela Rodriguez Wood River High School Hailey‚ ID 83333 ABSTRACT When male adolescents were unknowingly placed in an isolated environment with an attractive woman‚ there wasn’t enough viable data to determine whether or not their blood pressure increased. Based on our limited and unreliable data there is no significant increase in the heart rate or blood pressure of male adolescents when placed in this

was to improve or maintain a blood pressure of 120/80 or less. Goal: The goal in this case is to maintain a systolic pressure (upper number) at the January level of 116 or no greater than 120‚ while lowering the diastolic pressure (lower number) to below 80 by way of increased physical activity. Results: Initial results showed an increase rather than a decrease in diastolic pressure. Mode of activity was changed/modified‚ with the return of diastolic pressures to 80. The conclusion is increased

As blood flows through the body‚ it exerts stress on blood vessel walls; creating an effect known as blood pressure. Blood pressure is measured by “the force in the arteries when the heart beats (systolic pressure) and when the heart is at rest (diastolic pressure)” (American Heart Association [AHA]‚ 2008‚ para. 1). An average healthy adult’s blood pressure has a measurement of 120 over 80 or less (AHA‚ 2008‚ para. 3). “High blood pressure (also called hypertension) occurs when your blood moves through

The surface of the skin ulcerates which can‚ in turn‚ become infected. Eventually deeper tissues are damaged. It’s common in heels‚ buttocks‚ sacrum‚ ankles‚ hips and spine. 1.2 Pressure points on the body are: sacrum‚ hip bone‚ ankles‚ heels‚ elbows‚ spine‚ ribs‚ back and head and ears. 1.3 The risk factors

24-Hour Blood Pressure Monitoring In some patients‚ an elevated blood pressure reading taken during an office visit may not truly indicate hypertension—it could just be an occasional occurrence. These individuals are given a portable device to record their blood pressure over a 24-hour period. This helps us more accurately determine whether or not a patient usually has high blood pressure and requires treatment.
