When blood sucking insects inject anti-coagulants etc. where exactly are
these substances deposited? I'd always assumed that the stuff the bug
injects into the host was deposited extravascularly, otherwise it would
be rapidly swept away and its effects rapidly neutralized. In other
words, these parasite-derived substances are delivered intracutaneously
rather than intravenously.
