arachnoid granulations
Normally the pressure of the CSF is higher than that of the venous system, so CSF flows through the arachnoid villi and granulations into the blood
in sub-arachnoid space through sub-arachnoid villi
In the Arachnoid Granulations

Cerebral thrombosis occurs when a blood clot, or thrombus, forms within the brain itself, blocking the flow of blood through the affected vessel.
Dural venous sinuses are formed in areas where the two layers of the dura mater separate, forming spaces
Cerebral spinal fluid
no.
Cerebral spinal fluid, joint spaces, blood (in a healthy person), urine.
Cerebral spinal fluid
To provide alternative routes for blood to reach the brain in case of an obstruction
A "spinal tap" is also known as a "lumbar puncture".Lumbar puncture
Kidney
All of them. The only exclusion is the brain and spinal cord, they need cerebral spinal fluid (CSF) and that is in itself supplied by blood. So directly or indirectly, all systems of the body need blood. If they do not have access to blood they become necrotic and die. If enough body tissues that make up systems die, then the whole organism dies.
The kidney performs this function and it is thus:when the blood is more concentrated as in sugar,salts and so on we say the blood is hypertonic to the cells and this could shrink the cell but the kidney filter this salts from the blood and reabsorbs more water and a more concentrated urine is produced by anti dieretic hormone,but also sometimes the blood is hypotonic in terms of salts and so on in this case the kidney reabsorbs less water and restores some vital salts..so osmotic pressure is regulated.
Focal cerebral ischemia (FCI) is often results from a blood clot in the brain. The blood flow in the affected area is reduced. The reduction could be severe or mild but usually FCI causes irreversible injury to sensitive neurons.
Cerebral spinal fluid is supposed to provide nutrition to the brain and spinal cord. It is secreted from the arteries and drains into the veins. That is how the blood flows. From high pressure arteries to low pressure veins. In between the fluid goes to interstitial compartment. Here the spinal fluid is like the interstitial compartment.
If there are high amounts of white blood cells in cerebrospinal fluid, it could be a sign of meningitis or another infection. It could also signal the presence of a tumor or demyelinating condition.
