Blood is composed of 45% red blood cells or Erythrocytes and 55% plasma. The Blood also includes platelets or Thrombocytes for blood clotting and White blood cells or Leukocytes. Plasma is 91% water, meaning that a very large percentage of blood is simply water. When this water evaporates, as it has for the Martyrs of Akhmim and the body is dehydrated, the blood will cease to be liquid any longer because blood is only liquid because of the high percentage of blood within it, and will instead turn into a powdery coagulated substance. However, the miracle is that these bodies have been documented to bleed on many occasions, and in many diffrent places around the world.
