The function of the respiratory system is

• Serve as a pump that provides the pressure needed to push blood through the bloodstream

• Break down the macromolecules of food into smaller, simpler molecules that cells can use

• Protect the body from infections and diseases

• Bring oxygen into the body and get rid of carbon dioxide so that our cells can do cellular respiration

What is the function of the lungs?

• Moisten and warm the air coming into the respiratory tract

• Protect the windpipe from collapse

• Provide a large amount of surface area for the transfer of carbon dioxide and oxygen

• Split the trachea into two tubes

What causes the area of the chest cavity to increase, allowing the lungs to fill with air?

• Intercostals relax and the chest rises

• Intercostals contract and the chest rises

• Intercostals relax and the chest falls

• Intercostals contract and the chest falls

What is the function of bronchioles?

• To increase the space inside of the chest cavity and pull air into the lungs

• To provide more surface area for the transfer of gasses

• To distribute air to more areas of the lungs for better gas transfer

• To decrease the space inside of the chest cavity and push air out of the lungs
