@explainingmadicals: explaining.medicals What looks like a colorful coral reef is actually the inner lining of your small intestine, viewed through an endoscope. The countless finger-like projections covering its surface are called villi. These tiny structures dramatically increase the intestine's surface area, allowing your body to absorb nutrients, vitamins, minerals, water, and other essential molecules from the food you eat. Each villus is covered with even smaller projections called microvilli, creating an enormous absorptive surface that is often estimated to be comparable in size to a tennis court. During an endoscopy, gastroenterologists can directly examine this remarkable landscape to look for signs of inflammation, infection, bleeding, ulcers, celiac disease, polyps, or other digestive disorders. Although it resembles an underwater ecosystem, this intricate biological landscape is one of the most important structures keeping your body nourished. Every meal you eat depends on these microscopic projections to efficiently extract the nutrients needed for life. #diagnostics #biology #fyp #baby #MedicalEducation
