Peristalsis is the mechanism that propels content through the colon — essential for digestion and waste removal. In the large intestine, smooth muscle contractions occur in slow, coordinated waves. This movement helps absorb water, mix contents, and push stool toward the rectum. These contractions are controlled by the enteric nervous system, a dense network of neurons embedded in the gut wall. It functions independently, but also responds to input from the brain and autonomic nervous system. Th

🌊 Peristalsis: The Motion Behind Digestion 🌊 Your digestive system works nonstop, and peristalsis is at the heart of it all: 🔹 Small Intestine: Smooth muscle contractions move food slowly, maximizing nutrient absorption. 🔹 Large Intestine: Peristalsis transitions into strong, coordinated movements that push waste forward for elimination. This wave-like motion is essential for digestion and maintaining gut health. Watch our 3D animation to see peristalsis in action, from the small intestine t
