Why does the stomach move like it has a heartbeat?

The stomach appears to move like it has a heartbeat due to the rhythmic contractions of the smooth muscles in its wall, a process known as peristalsis. These contractions help mix and propel food through the digestive tract. Additionally, the stomach’s movements can be influenced by the autonomic nervous system and hormones, contributing to the sensation of pulsation. This coordinated activity is essential for effective digestion and nutrient absorption.
