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
Effacement of the ventral area of cerebral spinal fluid typically refers to a compression of the normal space surrounding the brain or spinal cord due to certain conditions like enlarged blood vessels or structural defects. This compression can lead to changes in brain anatomy or function and may require medical intervention to relieve the pressure on the nervous system.
Yes, cerebral blood flow is regulated by intrinsic autoregulatory mechanisms in the brain. These mechanisms ensure a relatively constant blood supply to meet the brain's metabolic demands, even when there are fluctuations in systemic blood pressure. Autoregulation helps to maintain stable oxygen and glucose delivery to the brain, supporting its constant function.
The kidney is the organ responsible for filtering the blood and removing waste products like urea. It also reabsorbs important substances like glucose and amino acids back into the bloodstream to maintain overall balance in the body.
Cerebral thrombosis occurs when a blood clot, or thrombus, forms within the brain itself, blocking the flow of blood through the affected vessel.
Hyperventilation can reduce intracranial pressure (ICP) by causing vasoconstriction of cerebral blood vessels, which decreases cerebral blood flow and thus decreases the volume of blood in the brain. However, prolonged hyperventilation should be avoided as it can lead to cerebral ischemia and harm the brain.

A "spinal tap" is also known as a "lumbar puncture".Lumbar puncture
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.
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.
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.
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.
The fluid that allows the brain to take in nutrients and remove wastes with blood is called cerebrospinal fluid (CSF). This clear, colorless fluid surrounds the brain and spinal cord, providing protection and support to these vital organs.

Blood reabsorbs : glucose, amino-acids, sodium ions, potassium ions, chlorine ions, water etc.
