Introducing: the venule and venous capillaries

My thinking is that (without looking at a detailed anatomy source like a textbook) maybe it's a vein that is still classified as a vein in anatomy and not what we would call a venule or the second half of a capillary bed containing 'venous blood'. Vein direct to heart not like branches of venules to vein to heart, maybe?

Edit: Wuh oh, I made a guess and decided to actually look into it more it's been fairly proven to be cultural belief mostly
