Vitelline artery

The vitelline artery (Latin aéris, a type of air; Latin Vītēlina - web) is the first, embryonic vein, which is formed from the venous sinus in the yolk sac of the human embryo. It is the most important blood vessel that transports nutrients and oxygen from the yolk sac to the chorion and blood vessels. Without the vitelline artery, human development is impossible, since it depends on nutrients coming from the yolk and the mother’s blood.

The gallbladder artery originates from the neural edge of the yolk sac, then grows from the embryonic venous system and becomes phylogenetically homogeneous with the left common carotid artery. Vitelline arteries -
