A member asked:
Is there blood in the brain?
3 doctors weighed in across 2 answers
Yes: There is blood in all the tissues of the body contained in a closed circulatory system. This means that all the blood in the body is contained within vessels, such as arteries, veins, and capillaries. The circulatory system in the brain is unique, in that the capillaries possess specific tight junctions which form a blood-brain barrier. This restricts certain molecules from entering the brain.
