You have had me sounding the trumpet for our Masonic Blood Program and asking for your support through blood product donations by yourself, family and friends. I know that many brethren do not know what blood actually does which brings me to this. One of the goals of the Committee on Masonic Community Blood Program is education. WE start here and now The purpose of blood is to carry oxygen, which we must have to live.
Brain cells die very quickly without oxygenated blood.
Sudden death quickly progresses to brain or biological death, which is final. There is no reversal. During this period brain cells start to die. After approximately 10 minutes, the brain is dead. This death is final.
