CARDINAL VEINS Meaning and
Definition
-
Cardinal veins refer to a set of major blood vessels found during early embryonic development in vertebrate organisms, including humans. They are responsible for carrying deoxygenated blood from the body back to the heart when the lungs have not yet developed.
During embryogenesis, cardinal veins are formed as a network of interconnected vessels that arise in the developing tissues, specifically around the developing heart. They play a critical role in the circulation of blood in the developing embryo before the establishment of the fully functional circulatory system. As the embryo grows, the cardinal veins undergo various morphological changes and ultimately give rise to important blood vessels in the body.
In humans, there are specifically two main cardinal veins: the anterior and posterior cardinal veins. The anterior cardinal veins primarily drain blood from the upper half of the embryo, while the posterior cardinal veins collect blood from the lower half. These two prominent veins ultimately fuse to form the common cardinal vein, which is an important structure in the developing circulatory system.
Understanding the development and functions of the cardinal veins is crucial in embryology and helps in comprehending the intricate processes involved in the formation and establishment of blood circulation in vertebrates.

Etymology of CARDINAL VEINS
The term "Cardinal Veins" has its etymology rooted in Latin and is derived from the word "cardinalis", meaning "principal", "chief", or "most important". In embryology, the "Cardinal Veins" are a group of major veins that develop in the early stages of the embryo. They play a crucial role in the formation of the circulatory system. The term "cardinal" highlights the significance and prominence of these veins in the embryonic development process.
