Blood Pressure Introduction The purpose of this lab is to learn recording the blood pressure, which is combined of two numbers: systolic and diastolic pressure. The systolic pressure is the force of blood in your arteries as the heart contracts and pushes it out. The diastolic pressure is the force of your blood between heartbeats. Circulations of the blood in an organism serve to transport all the provided information and sends proteins throughout the body’s cells. In addition, blood circulation maintains stability of cellular activity. Such function is possible only because of the heart, pumping the blood through a closed circuit of blood vessels, as well as make blood flow through the heart and the blood vessels is unidirectional, flowing into the heart from the pulmonary and systemic veins, and finally pumping the blood out of the heart into pulmonary and systemic arteries. The atrioventricular valve of left and right side are there to prevent the backward flow of blood from the ventricles into the atria. Where as, pulmonary semilunar valve and the aortic semilunar valve are to prevent the backward flow of blood from arteries into the ventricles. EXPERIMENTAL OBJECTIVES 1. To use an auscultatory method for an indirect determination of systemic arterial systolic and diastolic blood pressures and to correlate the appearance and disappearance of vascular sound with systolic and diastolic pressures respectively. 2. To measure, record, and compare systemic arterial blood pressure in the right arm and the left arm of the same Subject under identical conditions. 3. To measure, record, and compare systemic arterial blood pressures in the same Subject under different experimental conditions of rest and exercise. 4. To compute and compare pulse pressure and mean arterial pressure under different

    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.
