function of the cardiovascular and respiratory systems

Explain the function of the cardiovascular and respiratory systems as well as how these systems work together to meet the demands ofactivity. Discuss the process of gas exchange as well as coronary artery disease and chronic obstructive disease and explain how these chronicdiseases can lead to dysfunction of these systems.

To complete the following activity, you will need paper, a pen, and a clock or stopwatch with a second hand. To begin, take the Physical Activity Readiness Questionnaire (Links to an external site.)Links to an external site. (PAR-Q). The PAR-Q is a screening tool to determine if a person shouldcheck with his or her doctor prior to completing an exercise program. If it is determined that you should not exercise, please find an adult (18 years of age or older) family member or friend to complete theassessment for you who has been cleared to exercise through the PAR-Qassessment. You can record the results of your partner.

• Measure resting heart rate (refer to page 13 of the      text onhow to take a pulse).  Count your respirations in 1 minute.      Recordresults.
• If you are able to safely do so, exercise for 3 minutes      (jogin place, do jumping jacks, jump rope, push-ups, sit ups, etc.)
• Immediately take your pulse for 10 seconds. Record that      number.  Have your partner record your respirations for 1 minute.
• Rest for 5 minutes. Take your pulse again for 10      seconds. Count your breaths again for 1 minute.

In your initial post:

• Enter the results from the heart rate activity above.
• Describe the function of the cardiovascular system and      the respiratory system and how they work together.
• Describe how the cardiovascular system adjusts to meet      thedemands of exercise. Use appropriate terminology such as stroke     volume, respirations, and pulse.
• Describe why an untrained person’s heart rate and      breathingrate would take longer to return to a resting rate compared to a     person who is in good physical condition.
• Explain the relationship between heart rate and      breathing rate during physical activity.
• Discuss contributing factors to coronary artery disease     (CAD).  Explain how CAD leads to dysfunction of the cardiovascular     system.
• Discuss contributing factors of chronic obstructive      pulmonary disease (COPD). Explain how COPD leads to dysfunction of the     respiratory system.

Use two scholarly sources (one may be your course text) to supportyour initial post. All sources must be referenced and cited according to APA guidelines as outlined in the Ashford Writing Center. Your initialpost should be at least 250 words in length.

Guided Response: Respond to two peers; one replyshould relate to CAD and the other response should pertain to COPD.Please cover the following in each response: Contrast your answerspertaining to the contributing factors for CAD/COPD with those discussed by your peer. How could environmental factors contribute to CAD/COPD?Each peer response should be at least 100 words in length and supportedby one scholarly source.
