Change in respiratory rate during exercise Aim: To record and investigate how the breathing rate varies for the duration of light and heavy exercise. Introduction: When an individual exercises‚ the muscles being used needs extra energy from oxygen. The lungs pump oxygen to the heart‚ and then the heart pumps the oxygenated blood through the blood to the particular muscle that is working. The human body has a series of organs working together‚ which is named the respiration system. The organs involved

Expiratory reserve volume decreased due to the rapid increase in breath rate. Normal resting breath rate is at an average 11.6 breaths per minute increased to 27 breaths per minute after exercise. The increase in BR causes expiration length to go below its normal 3 second interval. Therefore decreasing ERV by .6 Liters. Inspiratory reserve volume decreased due to the rapid increase in breath rate. Normal resting breath rate is at an average 11.6 breaths per minute increased to 27 breaths per minute

LCT and UCT causes the endotherm’s metabolic rate to increase. We can hypothesize that when the temperature falls below the LCT or above the UCT‚ the percent O2 consumption will increase‚ and thus‚ the metabolic rate. The hypothesis was supported by the result received in this lab. The thermal neutral zone (TNZ) of an endotherm is its temperature tolerance range. For the mouse‚ this is about room temperature. It is seen that in the TNZ‚ the metabolic rate decreases from about 1.75 to 1 (Fig 1). During
