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.
Kids earn more screen time by answering fun educational questions.
Here are some example of questions about this video that kids may be asked in the 1Question app to earn screen time.
How many pairs of ribs do we have?1) 448782) 123) 154) 9
How many ribs do we have altogether?1) 22-262) 15-183) 448784) 28-34
Ribs that do not attach to the sternum can be connects to the other ribs by1) Cartilage2) Muscles3) Bones4) Tendons
What bones do the ribs connect to?1) Spine and Sternum2) Neck3) Skull4) Heart and lungs
What are floating ribs?1) Ribs that connect to the spine but not the sternum or other ribs2) Ribs that connect to the spine and the ribs above using cartilage3) Ribs that connect to the spine and sternum4) Ribs that aren't connected at all
What do floating ribs allow space for?1) The lungs to expand and contract with air2) The liver to expand and contract3) The stomach4) The ribs above it
Why are our ribs so important?1) If we didn't have protection for our heart and lungs we could easily die from impact or injury2) They are strong bones3) They connect to the spine4) We need ribs to help us breathe
What is the job of the ribs?1) To protect the heart, lungs and liver2) To protect the spine and stomach3) To help us breathe4) To protect the heart, lungs and spine
Recreational screen time
