In X and XI the posterior (commissural) vessels loop into the sperm and egg sacs, respectively. Posterior to about XII, lateral vessels may be blind, or may join the perivisceral sinus on the ventrolateral aspect of the gut; branching is variable, and sometimes not apparent. In a few segments, beginning in VIII or IX, 23 small blood glands at the perivisceral sinus are joined by short branches from the ventral blood vessel.
