Today is Monday. And as every Monday, Victoria, a healthy but lazy young girl, has promised herself to stop being a couched potato and start a workout routine that she will follow every single day! NOTE: Any resemblance to reality is pure coincidence. Well, Victoria gets ready and she just started running 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. What are the cardiovascular changes taking place as Victoria jogs? 2. How do you expect her heart rate to change? Why? What is the purpose of this change in heart rate? How is the status of her blood vessels at this moment (vasodilated or vasoconstricted)? Why? Which type of blood vessels are primarily targeted by these changes? Review the anatomy of capillaries and the pre- and post-capillary sphincters. How do you think is the status of the precapillary sphincters at her quadriceps muscle as she jogs? Victoria’s face has turned red. Is she producing an increased volume of blood? Why her cheeks look redder now? How does blood volume re-distribute in the body at this time? Why? Which organs or organs systems are a priority to receive blood flow at this moment? Which ones are not a priority? 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? Which neurotransmitters are being released in greater proportion? What about her respiratory rate? How has the rate and pattern of her respiration changed? Why? What changes do you expect to see in the diameter of her bronchial tree as she jogs (bronchoconstriction or bronchodilation)? What type of muscle (striated, cardiac, or smooth) is responsible of these changes in the diameter of the bronchi? 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)? What division of the nervous system is stimulating these responses in the bronchial tree? 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.
