heart rate and ventilation rate before‚ during and after moderate exercise. Introduction: I predict that during exercise the heart and respiratory rate (RR) will increase depending on the intensity of exercise and the resting rates will be restored soon after exercise has stopped. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. When the exercise is finished the heart and ventilation rates will gradually

The respiratory system The respiratory system is responsible for providing oxygen and removing carbon dioxide‚ heat and water vapours. All living creatures require oxygen and give off carbon dioxide. Oxygen is required for every cell in your body to function. Structure of the respiratory system: Normally air is taken in through your nose however sometimes it is taken in through your mouth and passes through a series of airways to reach the lungs. This series of airways is known as the respiratory

Abstract The primary purpose of this laboratory experiment was to record the effects that light exercise has on different cardiovascular functions such as mean blood pressure‚ cardiac out put‚ and total peripheral resistance by comparing both of the numerical values before and after exercise. Prior to exercise‚ the mean blood pressure (MBP) was 86.8 mmHg with a standard deviation of 7.4. After exercise‚ MBP was 96.3 mmHg with a standard deviation of 9.2. The cardiac output (CO) was 5.3 Liters/minute
