The Cardiovascular system is actually two different systems, the cardio system which refers to the heart and the vascular system which refers to the blood. So when talking about the cardiovascular system we are talking about the heart pumping blood around the body.

The Respiratory System is the system in which delivers oxygen from the air to our blood system and then return as waste products back outside into the air.

In order for our bodies to carry out any form of exercise, the cells in our body need oxygen. The cardio and the respiratory systems supply this oxygen to out body. To understand how the Cardio-respiratory system works you need to understand how, first of all, the heart works.

As you can see the heart is split into four different chambers, the right atria, right ventricle, the left atria, and the left ventricle. Deoxygenated blood enters the right atri

a through the Vena Cava; it passes through the Traipsed valve into the right ventricle. At this point the muscles in the right ventricle contract pushing the blood up through the pulmonary valve.
