Vein

After the deoxygenated blood goes into the venules they combine into larger veins.

The veins are the tubes that go through your body, bringing the used up blood back to the heart to be refreshed with new oxygen.

Venules

After the microcirculation happens at the capillaries, the deoxygenated blood that is all used up goes into small tubes called venules.

The many tiny tubes from the capillaries get combined into fewer bigger tubes called venules where the used up deoxygenated blood goes.
