Your Ribs

Your heart, lungs, and liver 1(be) all very important, and luckily you've got ribs to keep them safe. Ribs 2(act) like a cage of bones around your chest. It's easy to feel the bottom of this cage by running your fingers along the sides and front of your body, a few inches below your heart. If you 3(breathe) in deeply, you can easily 4(feel) your ribs right in the front of your body, too. Some thin kids can even see a few of their ribs right through their skin.

Your ribs come in pairs, and the left and right sides of each pair 5(be) exactly the same. Most people 6(have) 12 pairs of ribs, but some people 7(bear) with one or more extra ribs, and some people might have one pair less.

The very last two sets of ribs 8(call) floating ribs because they 9 ( not connect) to the sternum or the ribs above them. But don’t worry, these ribs can't ever float away. Like the rest of the ribs, they securely 10 (attach) to the spine in the back.

Taking Care of Bones

Your bones 1(help) you out every day so make sure you 2(take) care of them. Here 3(be) some tips:

Protect those skull bones (and your brain inside!) by wearing a helmet for bike riding and other sports. When you 4(use) a skateboard, in-line skates, or a scooter, be sure to add wrist supports and elbow and knee pads. Your bones in these places 5(thank) you if you 6 (have) a fall!

If you play sports like football, soccer, lacrosse, or ice hockey, always wear all the right equipment. Never play on a trampoline. Many kids end up with broken bones from jumping on them. Broken bones can eventually 7(heal), but it 8(take) a long time and 9(not be) much fun while you wait.

Strengthen your skeleton by drinking milk and eating other dairy products (like low-fat cheese or frozen yogurt). They all contain calcium, which 10 (help) bones harden and become strong.

Be active! Another way to strengthen your bones is through exercise like running, jumping, dancing, and playing sports.

When you 1(be) a baby, you 2(have) tiny hands, tiny feet, and tiny everything!

Slowly, as you 3(grow) older, everything (4become) a bit bigger, including your bones.

A baby's body 5(have) about 300 bones at birth. These eventually 6(fuse) (grow together) to form the 206 bones that adults have. Some of a baby's bones are made entirely of a special material called cartilage. Other bones in a baby are partly made of cartilage. This cartilage 7(be) soft and flexible. During childhood, as you 8(develop), the cartilage grows and is slowly replaced by bone, with help from calcium.

By the time you are about 25, this process 9(be) complete. After this 10(happen), there can be no more growth — the bones are as big as they will ever be. All of these bones make up a skeleton that is both very strong and very light.
