Anterior cardinal vein

Anterior Cardinal Vein

The Anterior Cardinal Vein (pronounced: an-TEER-ee-or KAR-din-al vayn) is a significant component of the embryonic cardiovascular system in vertebrates.

Etymology

The term 'Anterior Cardinal Vein' is derived from Latin. 'Anterior' means 'before' or 'in front of', 'Cardinal' refers to 'principal' or 'chief', and 'Vein' is derived from the Latin word 'Vena' which means 'blood vessel'.

Definition

The Anterior Cardinal Vein is one of the three pairs of cardinal veins, the others being the Posterior Cardinal Vein and the Common Cardinal Vein. These veins are responsible for draining the blood from the cranial half of the embryo.

Function

The Anterior Cardinal Vein drains deoxygenated blood from the cranial part of the embryo, which includes the head and neck regions. It then transports this blood to the heart for oxygenation.

Development

During embryonic development, the Anterior Cardinal Vein forms the Internal Jugular Vein, which is a major vein in the neck that drains blood from the brain, face, and neck.
