Human Body & Health

How Your Body Works

Learn English words about your amazing body, health, and hygiene!

📖 Let’s Learn Human Body & Health!

Your body is the most amazing machine in the world! It has over 200 bones, 600 muscles, and organs that work together 24 hours a day. Learning body and health vocabulary helps you understand your Science/EVS class and talk about health in English.

This topic covers the skeletal system (bones), major organs (heart, lungs, brain), nutrition (healthy food), and hygiene (keeping clean). These words connect your English learning directly to your Science textbook!

💡 The Rule

Body vocabulary includes: Systems (skeletal, muscular, digestive), Organs (heart, lungs, brain, stomach), Nutrition (protein, vitamins, carbohydrates), and Hygiene (sanitation, germs, immunity).

🎯 Key Concept

🫀 Heart = pumps blood through your body
🧠 Brain = controls thinking, movement, senses
🦴 Skeleton = the framework of 206 bones
💪 Muscles = help you move and lift things
