Breana Campos 519 Working Out the Heart Abstract For this exercise in lab, we produced and compared the cardiopulmonary effects before and after physical exercise from 4 classmates of both genders. An ECG trace graph was also obtained, showing the electrical activity of the heart. This electrocardiogram data was produced from an ECG program on the Powerlab computer. We used the measurements of respiratory rate, pulse rate and mean arterial pressure as factors to whether gender will have an affect on the results. There was a strong positive rise in cardiopulmonary activity in the heart after an exercise action. When comparing the data to genders, it showed increase of activity that was mostly uniform for both genders. The factor that had slight contrast was the mean arterial pressure. Which could have fluctuated for several reasons but not strong enough to correlate it to gender. Each of the measurements used in lab gives important insight on how our hearts are preforming. Introduction The heart is an extremely important organ that has many roles throughout the body. When something affects your heart, your whole body can suffer. Therefore, understanding the heart and its health signs is vital to good overall health of the body. It is a very complex structure that is always working to keep us alive. The heart keeps blood moving and pumping throughout the

The arteries carry oxygenated blood away from the body to the tissues. 1 This especially important to the muscles when involved in physical activity. While exercising, your muscles are working harder than normal and burning energy. The heart must keep up and supply more oxygen to the muscles to keep producing ATP (energy). This is what accelerates your breathing and heart rates. In order for the blood to properly circulate, the veins must carry deoxygenated blood back to the heart. The mechanics of circulation are performed by the contraction phase of the cycle, systole, and the relaxation phase, diastole. 2 The cardiac output in each ventricle is used in the measurements of the heart. These measurements include pulse rate, respiratory rate and mean arterial pressure. The purpose of this experiment is to analysis these measurements in 4 males and 4 female classmates in relation to how exercise affects the heart. Furthermore, we will be comparing the
