Inside the Intestinal Villi

An immersive passage through the small intestine, revealing the villi and their brush border at cellular scale. Finger-like villi project from the intestinal lining, while the enterocytes covering them bear microscopic microvilli that form the brush border. Together, these structures increase the surface area available for nutrient absorption. Brush-border enzymes also contribute to the final stages of digestion.

The sequence places the gut microbiota within this environment, highlighting its roles in nutrient metabolism, intestinal barrier function and immune regulation
