Of the total blood and oxygen that is produced in our body, the brain gets 20% of it.
When the blood supply to the brain stops, it is almost after 8-10 seconds that the brain starts losing the consciousness.
The brain is capable of surviving for 5 to 6 minutes only if it doesn’t get oxygen after which it dies.
The blood vessels that are present in the brain are almost 100,000 miles in length.
