Blood Supply to Brain
Well supplied with oxygen and nutrients, comsumes 20% of total serum O2 at rest and 25% of total serum glucose
Interruption in oxygen supply may cause unconsciousness, 4 minute impairment of 02 may cause permanent damage
Low serum glucose may cause mental confusion, dizziness, convulsions, loss of consciousness
BBB
protects brain and prevents entry of most substances, however it is permeable to glucose, 02, CO2, water, alcohol, caffeine, nicotine, heroin, anesthetics.
Partially soluble to:
creatine, urea, most ions.
