Blood travels away from the heart in the arteries which branch to form arterioles which eventually develop into bed of capillaries (site of gas and nutrient exchange). Stroke volume (SV) response to exercise depends on changes in cardiac filling, intrinsic myocardial contractility and left ventricular afterload.
