Definition
The term 'vena cerebri' refers to the cerebral veins, which are blood vessels that drain blood from the brain. Think of them as the brain's plumbing system, carrying away used blood. They collect deoxygenated blood and waste products from the brain tissue. These veins help maintain healthy brain function by removing metabolic byproducts. Unlike arteries, which bring oxygenated blood *to* the brain, these veins carry blood away. They eventually empty into larger veins that lead out of the skull, ensuring continuous circulation.
