venous
adj. C1 Advanced US //ˈvinəs// UK //vˈɛnəs// ve·nous
adj. relating to veins, which are the blood vessels that carry blood back to the heart.
adj. relating to or characteristic of veins. Often used in medical contexts to describe the flow of blood or the structure of the circulatory system.
The doctor checked the venous flow in my legs.
The patient's venous system was examined to ensure there were no blockages causing the swelling.
In the circulatory system, venous blood is typically deoxygenated and returns to the heart at a lower pressure than arterial blood.
Morphologically vein + -ous, which is a borrowing from Latin vēnōsus (“full of veins, veiny”), from vēna (“a blood vessel, vein”) + -ōsus (“-ous, -ose”, adjectival suffix). Doublet of venose.
