Peristalsis is a series of wave-like muscle contractions that moves food to different processing stations in the digestive tract. The process of peristalsis begins in the esophagus when a bolus of food is swallowed. The strong wave-like motions of the smooth muscle in the esophagus carry the food to the stomach, where further digestion takes place.

Now, how does it allow you to drink water while hanging upside down?

When you're upright, gravity helps move the water down your esophagus and into your stomach. However, when you're upside down, gravity is working against you. This is where peristalsis comes in.

Even when you're upside down, the muscles in your esophagus continue to contract in a wave-like manner, which helps to push the water towards your stomach. So, despite the force of gravity, peristalsis ensures that the water you drink can reach your stomach, even if you're hanging upside down.
