question 23

Multiple Choice

Which statement best describes boundary layer separation in the carotid bulb?

• A) Flow moves forward on the wall opposite the flow divide between the internal and external carotid arteries.
• B) Both forward and reverse flow patterns are present as a result of dilatation of the carotid bulb and the presence of a pressure-flow gradient on the posterolateral wall of the bulb.
