Nadiya Abramyuk Bio205 LAB Instructor: Faiza Peetz BLOOD PRESSURE Introduction The purpose of this lab is to record the blood pressure, which is comprised of two numbers: systolic and diastolic pressure. The systolic pressure is the force of blood in the arteries which moves as the heart contracts and pushes it out. A force of the blood between the heartbeats is diastolic pressure. The systolic pressure is the highest arterial pressure reached during ventricular systole, which occurs when the heart contracts. The normal range of systolic pressures for a resting adult is 100 - 139 mm Hg. The diastolic pressure is the lowest arterial pressure reached during ventricular diastole, when the heart rate is relaxed between contractions. The normal range of diastolic pressures for a resting adult is 60 - 89 mm Hg. In order to record accurately the blood pressure will help understanding of circulation of the blood. It is important to know that circulating of blood is communication of system between the body’s cells, it keeps relatively stable internal environment for optimum cellular activity. Blood flow through the heart and the blood vessels is unidirectional, flowing into the heart from the pulmonary and systemic veins, and out of the heart into pulmonary and systemic arteries. Blood flow through the chambers of the heart is unidirectional because of the action of four valves inside the heart that normally prevent retrograde or backward flow during the cardiac cycle which is one heartbeat. An instrument that will be used to measure the blood pressure is sphygmomanometer. The stethoscope will help to hear the first and second sounds. Blood pressure is the measure of the force exerted by the blood against the walls and arteries and veins. Normal blood pressure is considered to be anything below 120/80. Prehypertension is defined as a systolic reading between 120 and 129, diastolic reading lower than 80. Hypertension is defined as blood pressure of 130/80 or higher.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
