Please tell me if it is correct to use the word doublingly in the following context:
All the blood vessels of the greater circulation are divided into dozens of levels. Vessels of one level transfer doublingly to the ones of the next.
The meaning is that each blood vessel branches into two ones. Will it be clear to you?
Thanks
Well, then, what word can be used instead?
Each vessel branches into two.
Each vessel divides in two.
Each vessel divides into two branches.
