Today’s Walking Classroom podcast focuses on the circulatory system. The circulatory system is made up of the heart, blood vessels, and blood. They all work together to deliver oxygen to the cells of your body and dispose of carbon dioxide waste. The heart is divided into four chambers, and each chamber has a special job.
