The root "ven/o" signifies which type of blood vessel?

The root "ven/o" specifically refers to veins, which are the blood vessels that carry deoxygenated blood back to the heart from various parts of the body. This root is derived from the Latin word "vena," meaning "vein." When you encounter medical terms that contain "ven/o," such as "venogram" (an imaging study of veins) or "venipuncture" (the puncture of a vein to draw blood), these references to veins emphasize the connection to this specific type of blood vessel. Understanding this root is essential for accurately interpreting various medical terms related to vascular anatomy and physiology.
