Jugular veins are the veins that drain blood from brain, face and neck, it returns to the heart through the Superior vena Cava.
Step-by-step explanation:
The veins of the central nervous system drain deoxygenated blood from the cerebrum, cerebellum, brainstem and spinal cord. The main blood vessels are external jugular vein and interior jugular vein.
These vessels runs at the right and left side of the neck. Jugular veins spreads the bacteria through the bloodstream. The inflammation surrounding the vein and compression of vein leads to clot formation.
