CSF is cerebrospinal fluid . It is a colorless fluid found in the brain and spine. It is formed in the lateral ventricles from where it circulates through the interventricular foramens into the third ventricle and finally into the fourth ventricle.
CSF is in the subarachnoid space (deep to the arachnoid mater and superficial to the pia mater)
CSF is reabsorbed by blood vessels located within the meninges. A careful balance between CSF production and reabsorption is important to avoid the accumulation of too much CSF.
In blood and CSF
Pressure is necessary to circulate the blood to all extremities of the body.
It is a continuous process.
To circulate blood through the body.
Around 60 seconds
CSF is returned to the blood stream through lateral ventricles
Normal CSF should contain no infection-fighting cells (white blood cells), so the presence of white blood cells in CSF is another indication of meningitis.
Since blood-csf barrier is not well developed in neonates protein leak from blood to csf occurs...so csf protein is high in neonates and infants...for similar reason csf protein is elevated in all meningitis due to vascular permeability...
Swelling of the meninges may interfere with the normal absorption of CSF by blood vessels, causing accumulation of CSF and damage from the resulting pressure on the brain.
In blood and CSF
The person will die if the blood does not circulate. Blood is necessary to supply food and oxygen to the body.
veins
You may not know this but as well as pumping, your heart also sucks blood back into its' chambers like a vaccum which is how your blood gets returned to your heart.

circulate
YES
Circulate blood.
