separated by a valve‚ which prevents the backflow of blood. Blood enters the heart through the inferior and superior vena cava carrying deoxygenated blood. The vena cava then empties into the right atrium. When the right ventricle is relaxed‚ blood flows from the atrium into the right ventricle. The blood is then pushed through the pulmonary semilunar valve into the pulmonary artery where it carries deoxygenated blood to the lungs for oxygenation. The blood then flows back into the heart from the lungs

This experiment involves measuring and identifying the change in blood pressure. In this experiment‚ measurements of systolic arterial pressure‚ diastole arteriole pressure‚ and pulse rate were recorded and observed. The effects of changes in the body were observed and measured during body positioning‚ exercise‚ and cognitive stress. The purpose of this lab experiment was to test multiple variables that can have an effect on blood pressure and pulse. As stated‚ the following variables that were tested
