As you work out, your body needs more energy. It takes more oxygen and nutrients from your blood, so your blood must move more to continue to supply your body with the resources it needs. This means your heart needs to pump harder, and just like when you lift weights your arm muscles get stronger, when your heart pumps harder its muscles get stronger. So people who have good cardio fitness have a heart that is very strong and can easily pump a lot of blood when you need it.
