Read the following scenario and analyze it by answering the questions below using your explanations
of the concepts learned in this module and in this course … This is your ultimately opportunity to show all you have learned in THIS course.
Complete the following activity and post your analysis AND the video (bullet 10) into the forum.
Carefully read and follow the directions specified for the activity.
Review the rubric used to grade this assignment.
Today is Monday, and as every Monday, Victoria, a healthy but lazy young girl, has promised herself to stop being a couch potato and start an exercise routine that she will follow every single
day! NOTE: Any resemblance to reality is pure coincidence. Well, Victoria puts her sneakers on, gets ready and just starts to run around the neighborhood. She is all sweaty and her face has
turned red!
Answer the following questions comparing the conditions at rest with the changes occurring in Victoria
as she starts jogging.
1. What are the cardiovascular changes taking place as Victoria jogs?
2. How do you expect her heart rate to change? Why?
1. What is the purpose of this change in heart rate?
2. Which division of the nervous system governs these changes?
3. How is the status of her blood vessels at this moment (vasodilated or vasoconstricted)? Why?
1. Which type of blood vessels are primarily targeted by these changes?
4. Review the anatomy of capillaries and the pre- and post-capillary sphincters. What do you think
is the status of the precapillary sphincters at her quadriceps muscle as she jogs?
5. Victoria’s face has turned red. How do you explain this phenomenon?
1. Is she producing an increased volume of blood?
2. Why do her cheeks look redder now?
3. How does blood volume re-distribute in the body at this time? Why?
4. Which organs or organs systems are a priority to receive blood flow at this moment?
5. Which ones are not a priority?
6. Regarding the nervous system (covered in module 4), what division of the nervous system is
causing these responses in the heart contractility, heart rate, and blood vessels diameter? How?
1. Which neurotransmitters are being released in greater proportion?
7. What about her respiratory rate?
1. How has the rate and pattern of her respiration changed? Why?
8. What changes do you expect to see in the diameter of her bronchial tree as she jogs
(bronchoconstriction or bronchodilation)?
1. What type of muscle (striated, cardiac, or smooth) is responsible of these changes in the
diameter of the bronchi?
2. Where is this type of muscle specifically located in the bronchial tree (which types of
bronchi have this type of muscle, and hence, can react and change diameter)?
3. What division of the nervous system is stimulating these responses in the bronchial
tree?
9. Describe the immediate and long-term effects of regular cardiorespiratory endurance exercise.
Briefly describe the benefits of regular exercise in mental health and in other organ systems of
the body, including the osseous, muscular, integumentary, digestive, etc.
10. Last but not least, describe and show in a short video (30 seconds to 1-minute max.!) how to
palpate the superficial arteries covered in this course to determine Victoria’s pulse and heart
rate.
Use anatomical terminology and surface anatomy landmarks (graded) to describe and show how to
locate the following arteries:
i. Superficial temporal artery
ii. Common carotid artery (why we should only palpate one of these arteries at a time?)
iii. Brachial artery
iv. Radial artery
v. Femoral artery
vi. Popliteal artery
vii. Posterior tibial artery
viii. Dorsalis pedis artery
