A novel technique for preparing transparent natural blood vessels revealed paired spiral secondary flows and recirculation zones in venous valves, dog abdominal aorta, and human carotid sinus.
A novel technique for preparing transparent natural blood vessels enables detailed visualization of complex flow patterns, such as spiral secondary flows and recirculation zones, in specific vascular regions.
A novel technique to prepare isolated transparent natural blood vessels was developed and used to study the detailed flow patterns in some regions of the circulation. It was found that paired spiral secondary flows and recirculation zones form downstream of venous valves, at the arterial T-junctions in the dog abdominal aorta, and in the human carotid sinus over a wide range of geometrical and flow conditions, including the time-averaged mean values of the physiological flow rates.
