Learning time​

Kids learn by watching short, engaging video lessons.

Put your hands on your stomach. Now, breathe in and out really deeply. Did you feel the bones? That is your rib cage. Your rib cage is made-up of 12 pairs of ribs. The job of these bones is to protect your heart and your lungs and your liver. Most of us have 12 pairs of ribs. Some of us have 11 and some of us have 13. The first seven pairs of ribs connect to our spine and to a bone down the middle called our sternum. Following that, we have 4 to 5 sets of ribs that are attached to our spine but aren't attached to our sternum. They attach to the ribs above it using cartilage. And finally, at the bottom, we have what's called floating ribs. Floating ribs connect to a spine but not to any of the ribs above or the sternum. This gives our rib cage room to expand and decrease as we breathe.
