choroid plexus
CSF is produced in the brain by modified Ependymal_cellsin the Choroid_plexus(approx. 50-70%), and the remainder is formed around blood vessels and along ventricular walls..................................
Spinal fluid (cerebrospinal fluid) is formed by the choroid plexus - modified blood vessels with a mossy appearance that line the floor of the lateral cerebral ventricles. The choioid plexus filters the blood and only lets the plasma through.
aorta and pulmonary artery
Cerebrospinal fluid is formed from blood by the choroid. This is usually produced through the process of filtration of blood in the brain.
the major part of the CSF is produced in the brain by the ependymal cells in the choroid plexus. the rest is formed around blood vessels and along ventricular walls.

CSF, otherwise known as cerebrospinal fluid is a colorless liquid which fills and surrounds the brain and spinal cord, creating a protective barrier. It originates in the ventricles of the brain.
It is formed by filtration of blood through the fenestrations of the choroidal capillaries in the choroid plexus. It is flows by the active transport of substances (Particularly sodium ions) across the choroid epithelium into the ventricle, water then flows passively across to maintain osmotic balance. It has also been shown that if the choroid plexus was removed the ventricles still produced substantial quantities of CSF, though less than normal. And is generally considered to be fluid movement from CNS capillaries into the parenchyma of the brain, and from there across the ependymal lining into the ventricle.
Ideally, cerebrospinal fluid should not contain blood. The presence of blood in cerebrospinal fluid can indicate a potential injury or bleeding within the brain or spinal cord. It is important to investigate the cause of the blood in the cerebrospinal fluid to determine the appropriate treatment.
Cerebrospinal fluid is formed in the human body through a process where blood plasma is filtered by the choroid plexus in the brain's ventricles. This filtration process helps create the clear fluid that surrounds and protects the brain and spinal cord.
The cranial cavity contains the brain, pineal and hypophysis cerebri, parts of the cranial and spinal nerves, blood vessels, meninges and cerebrospinal fluid.
