Pulse rate is easily felt when gently pressing the arteries in the wrist or neck region (Fig. 1).

Arteries supply the thin vasculature in the capillary bed where the blood flow encounters a large increase in resistance due to the narrow vasculature and blood flow is reduced, albeit the pressure may still be relatively high. The capillary bed, in turn, feeds the venous system (Fig. 2), characterized by a low blood pressure and relatively slow and continuous blood flow. This steady, slow blood flow is apparent during blood sampling procedures from the veins in the arm, where I have never noticed any pulsatile flow by visual observation (anecdotal evidence, but quite representative I'm sure).

Is there an observable/measurable pulse in the capillaries and veins, or is blood flow continuous in these vessels?
