gure : Average values of class results Cardiovascular Function Jonathon Nguyen 16323012 10/10/08 Introduction: The cardiovascular system is a part of the circulatory system that deals with the distribution of blood throughout the body through heart, the so called pump of the system, and is distributed through the body in a large network of veins and arteries. In humans, it is a closed system, which means that the blood never actually leaves the network of veins and arteries, but other substances such as oxygen and nutrients can diffuse from the artery to the vein. This is important to maintain a healthy system as it discharges waste products such as CO 2 and helps the body retain a reasonable pH level. This experiment is aimed to explain the effects that exercise has on body compared to the normal resting state. In addition, this experiment helps to explore different places to find the pulse and measure them. Blood pressure is measured by a sphygmomanometer and is taken from the brachial artery, this experiment thoroughly explore the method of how this is done. Materials: stethoscope sphygmomanometer timer a flight of stair Methods: 1. Measure the resting blood pressure using the auscultatory method. Obtain 5 measurements and average out the readings to obtain the resting systolic and diastolic pressure of the subject. 2. Calculate the pulse rate, radial pulse rate and MAP and record them in a table. 3. The test subject should now run up and down a flight of stairs for 5 minutes. 4. The blood pressure is then measured again using the auscultatory method. 5. Calculate the pulse rate, radial pulse rate and MAP and record them in a table. 6. Once the test subject has returned to a normal resting state, another run up and down a flight of stairs for 5 minutes is preformed. 7.
