Journeys: Small intestine. Stop 2

Squeeze wave

How does food move along such a long gut? Squeeze the gut behind the ball of food!

The gut's muscles squeezed and pushed the ball forward.

No need to squeeze in front, the ball will get stuck. Squeeze behind it!

The muscles squeeze in a wave, one after another. That is why food moves on even when you stand on your head!
