Trace the pathway of a red blood cell from the brachial vein to the femoral artery- include the path through each part of the heart and name the blood vessels it would pass through.

The capillary beds surrounding these structures in the lungs are the site for gas exchange:

This blood vessel is defined as transporting blood away from the heart and has a thicker tunica media.

After a normal exhalation, this would be the volume of air you could forcefully exhale after.
