Original Question

The vasculature is a dynamic system that responds to local tissue demands for metabolites and removal of waste products. Vascular smooth muscle differs from other muscle types in structure and how it responds to electrical and agonist stimulation. The smooth muscle system responds to the demands of exercise by increasing blood flow to some tissues whilst reducing flow to others so targeting metabolic substrates to the most appropriate place according to the tissue demands. This tutorial aims to explore the mechanisms behind this vasoregulation. 1) Increases in cardiac output are caused by an increase in heart rate and stroke volume. The volume of blood pumped into the systemic circulation per minute rises from 4.5 – 5 L to around 25 L/min in heavy exercise. a. Why is it important to increase blood flow? b. Suggest a hypothesis as to why during heavy exercise the systolic blood pressure is increased, but diastolic pressure remains approximately constant.
