Our Body — Practice Quiz

206

Step 1: A baby is born with about 300 bones. Step 2: As the baby grows into an adult, some of these bones join together and become one bone. Step 3: For example, the bones in the skull join together as we grow. Step 4: By the time a person becomes an adult, the total number of bones becomes 206. So the correct answer is 206!

Give shape to our body

Step 1: Think about what would happen if we had no bones at all — our body would be like jelly and have no shape! Step 2: The skeleton is the framework of bones. Step 3: The skeleton gives shape to our body, helps us stand straight and walk, and protects delicate parts like the heart and brain. Step 4: Digesting food, seeing colours, and hearing sounds are done by other body parts, not by the skeleton. So giving shape to our body is correct!

Brain

Step 1: Some body parts are very soft and can get hurt easily — these are called delicate body parts. Step 2: The skeleton protects these delicate parts. Step 3: The skull (bone of the head) protects the brain. The rib cage (bones in the chest) protects the heart and lungs. Step 4: Eyes, tongue, and fingers are not surrounded by a large bone cage for protection. So brain is the correct answer!

Where two or more bones are joined together

Step 1: Our body can bend and move in different directions. Step 2: This movement is possible because of joints. Step 3: A joint is the place where two or more bones meet and are joined together. Step 4: The knee, elbow, shoulder, and neck are all examples of joints. Step 5: Muscles being soft, smooth skin, and blood flow are not related to joints. So the correct answer is where two or more bones are joined together!
