why are facial veins not tortuous?

It lies behind the external maxillary (facial) artery and follows a less tortuous course. The facial vein has no valves, and its walls are not so flaccid as most superficial veins.
how is Retromandibular vein formed?
The retromandibular vein (temporomaxillary vein, posterior facial vein), formed by the union of the superficial temporal and maxillary veins, descends in the substance of the parotid gland, superficial to the external carotid artery but beneath the facial nerve, between the ramus of the mandible and the

Why is the jugular vein so important?
IT’S A REAL BRAIN DRAIN. “The jugular vein is an important body part because it drains deoxygenated blood from the head and the neck,” Ashley tells Mental Floss. “Most important is to drain the brain. If you block the jugular veins, the pressure in the brain goes up.” You may also read,

What veins drain into the internal jugular vein?

What is the vein in your forehead called?
The frontal vein (supratrochlear vein) begins on the forehead in a venous plexus which communicates with the frontal branches of the superficial temporal vein. The veins converge to form a single trunk, which runs downward near the middle line of the forehead parallel with the vein of the opposite side.
Are there arteries in your face?

It ends underneath the eye, but there it is called the angular artery. The facial artery branches into many smaller blood vessels around the face and oral cavity.
Where does the pterygoid plexus drain into?
The pterygoid plexus of veins becomes the maxillary vein. The maxillary vein and the superficial temporal vein later join to become the retromandibular vein. The posterior branch of the retromandibular vein and posterior auricular vein then form the external jugular vein, which empties into the subclavian vein.
