What is the protective mechanism that helps maintain a stable environment for the brain?

The brain is floating in cerebral fluid within the skull and the fluid acts as a shock absorber for the brain. The hypothalamus regulates body temperature maintaining a perfect environment for the brain to survive. The brain also requires oxygen and glucose to survive and therefore a lack of oxygen caused by a decrease in either red blood cells to distribute the oxygen or a reduce intake of oxygen in the lungs for any reason whether disease or injury. A decrease or excessive increase in glucose will also cause damage to the brain as this, along with oxygen, is considered essential brain 'food'.
