How Food Becomes You
by Anonymous · ⭐ 0 · 🍴 0
🍞 How does the food we eat become part of our body? Large nutrients can't enter as they are! Count the pieces to find the pattern: saliva breaks down starch, gastric juice digests protein, and fat is only broken down in the small intestine. 🌾 The inner wall of the small intestine is folded with villi, expanding its area by 600 times! There are two paths: glucose enters capillaries, while fatty acids go into lacteals to avoid clogging blood vessels. ❤️ Finally, we reach the heart! What separates arteries from veins is direction, not oxygen level. Explore and see for yourself! Built with code — why not remix it to add breathing too?
About this app
From Food to Blood is an interactive middle school science app about how nutrients are digested, absorbed, and transported through the body. Explore three sections—digestion, absorption, and circulation—by selecting nutrients, organs, routes, and blood vessels to see how the body processes them. The app highlights nutrient-specific digestive juices, the 600-fold increase in small-intestine surface area, and why arteries and veins are defined by direction rather than oxygen content.
Use cases
- Middle school students studying digestion and circulation
- Teachers demonstrating nutrient breakdown and absorption
- Learners reviewing how glucose, amino acids, and fatty acids travel
- Families exploring basic human biology through interactive activities
Features
- Interactive digestion activities for starch, protein, and fat
- Visual breakdown of nutrients into absorbable molecules
- Small-intestine absorption simulations using capillaries and lymph vessels
- Four selectable intestinal surface structures from smooth to microvilli
- Circulation activities covering the aorta, vena cava, pulmonary artery, and pulmonary vein
- Reset, next-step, multilingual interface, and sound controls
