Etymology
Origin of vascular
From the New Latin word vāsculāris, dating back to 1665–75. See vasculum, -ar 1
Explanation
Use the adjective vascular when you're talking about blood vessels. One side effect of long-term smoking is vascular disease. The word vascular comes up in medicine and anatomy whenever there's discussion of the circulatory system, the series of vessels carrying blood around the body. Plants have vascular systems too, to carry water and nutrients throughout their systems. The word vascular comes from the Latin vascularis, "of or pertaining to vessels or tubes."
