The fact the at rings are incomplete posteriorly allows a food bolus to bulge during its transport to the stomach?
The incomplete posterior rings in the esophagus create a weaker structural support, which allows for the expansion of the esophagus as a food bolus passes through. This bulging helps accommodate the passage of larger food items or swallowed air, facilitating the movement of the bolus towards the stomach.

Why does Neptunes rings seem to be incomplete?
Neptune's rings may seem incomplete because they are made up of small particles and debris that are scattered over a wide area. These particles may not be evenly distributed and may have gaps or spaces between them, creating the appearance of an incomplete ring. Additionally, Neptune's rings are relatively faint and not as dense as the rings of other gas giants, which can also contribute to the perceived incompleteness.
Why does Neptune have incomplete rings?
Neptune's rings are incomplete because they are made up of individual ring arcs that don't fully encircle the planet. This is likely due to gravitational interactions with nearby moons that help shape and maintain the ring structure. The dynamic nature of the system means that new ring material is constantly being supplied and lost, leading to the incomplete appearance of the rings.
