Answer the fоllоwing questiоns regаrding the physiologicаl responses to exercise: (а) (2) Why is it that cardiovascular function & alveolar ventilation can be increased following the onset of exercise when there is no measurable change in arterial PC02? (b) (4) What is the role of epinephrine (consider metabolic as well as cardiovascular effects; list at least 4 for full credit)? (c) (2) What effects does exercise have on pulmonary vascular resistance and why? (d) (2) How is it that blood [glucose] can rise during intense exercise without a concurrent increase in plasma insulin levels? (e) (3) During a long-term (many hours) bout of exercise(eg. a marathon), what is the primary source of energy to active muscles, and what is/are the metabolic pathway(s) involved? (f) (3) Why does TPR decrease during prolonged, vigorous exercise, even with compensatory vasoconstriction occurring in some vascular beds? (hint: more than one possibility)
