3. During exercise: ERV will not change. 4. During exercise: VC will increase. 5.
Estimate the length of the refractory period for the pyramidal neuron.50msec DISCUSSION 1. In Experiment 1, discuss why the amplitude of the action potential did not increase as stimulation voltage increased above threshold. Once over threshold, the maximum amplitude is no longer able. The action potential is everything or nothing. 2.
5. Certain respiratory disorders, such as emphysema, reduce the capacity of the lungs to recoil elastically. Which respiratory volumes will this condition affect? Explain the impact on gas exchange. Emphysema affects the maximal volume of air that can be exhaled.
Case Study Progress. The room air ABG results are reviewed. According to the results M.M. is in respiratory acidosis. Because of M.M.’s increased Kussmaul respirations he is unable to fully express carbon dioxide from his lungs causing the carbon dioxide concentration of the blood to increase and the pH to decrease causing acidosis.
Introduction: The purpose of this lab is to identify the significant differences between heart rates and blood pressures based on an individual’s sex, lifestyle and physical activity during a given period of time. Hypothesis: In response to the different levels of activity I feel the more active a person is their pulse and BP will increase. I also feel that based on their lifestyles, someone with a more active or athletic lifestyle would have a less significant change in their vitals as opposed to someone who is less active and even more so with a smoker. Materials: Blood pressure cuffs, stethoscopes, the BP pulse and MAP chart provided, 4 individuals that fit the specified profiles, timer/clock/stopwatch. Procedure: To obtain comparable
6. Describe how frequency of sEMG spikes changed with increasing muscle load. The frequency of sEMG spikes started increasing as the muscle load increased until it reached it's optimal point at a 5 lb threshold and then started to slowly decreased thereafter. 7. Based on changes in amplitude and frequency of sEMG, did motor unit activation increase, decrease, or stay the same with increasing muscle load?
By blocking beta receptors, the heart rate will be slowed and reduces demand for oxygen and contractility. By slowing the heart rate, diastole will increase and the time of coronary blood flow will increase. With a decreased heart rate and contractility, the amount of work the heart has will also decrease. Calcium channel blockers are used to treat
Maximal heart rate can be estimated by subtracting the person's age (in years) from: a. 200 b. 210 c. 220 d. 230 12. The anaerobic system of producing energy generates considerably more ATP than the aerobic one. a.
