As a Doctor, the Doctor had to learn everything of blood whether it was for Blood Spatter Analysis or if it was for medical practice. Whether it was for solving a crime scene or saving a life Blood was always a crucial factor. The prevention of excessive blood loss was no where less crucial to surviving than the idea of eating food, waste removal, or even the protection of infections. One of the most important preventions of blood loss was the process of clotting. The Doctor learned that even without a proper coagulation system the smallest of injuries could easily lead to death from blood loss.
Through the process of Clotting the body however must control not to do it excessively as this was equally important. The Doctor marveled the intricacies of the human body as the clotting mechanism was a system that could form to help an injury or create injury within the circulatory system. The necessary components for a functional clotting system are all of the components within the blood, these were the platelets, the fibrinogens, the prothrombins, and even calcium with the clotting factors.
Blood was the life source of the human body, it was the process of giving life through the body as it passed through the arteries, veins and capillaries found throughout the body. The Oxygenated blood would leave the left side of the heart through the aorta, the arteries would progressively become smaller and culminate into the capillaries at remarkable size which was the diameter of one tenth of a human hair. Even though the capillaries were remarkably small they were the sites where oxygen was released and the waste products were collected. The veins which ranges between 1 millimeter to 1.5 centimeters in diameter will serve the return of blood from the capillaries to the heart and lungs.
Before the Doctor may delve deeper of Blood Spatter Analysis he needed to learn more about blood. This ranged from the composition of blood, such as the Volume, the pH levels of blood, plasma, the components and composition found in plasma, the white blood cells also called leucocytes, red blood cells also called erythrocytes, hemogoblins, plateletes and the clotting factors. Then the Doctor had to learn the physical properties found in blood such as the viscosity which was the measurement of its resistance, or the thickness of the liquid, the surface tension, and the relative density. The Doctor even had to learn the effects of drugs and alcohol with bloodstains as this could significantly change the viscosity, the surface tension and the relative density found in blood.
Of course however the Doctor had to take everything one at a time, and the first part the Doctor had to go into, was the Composition of Blood.
Normal pH levels of blood was 7.4 and normally compromised approximately 8 to 9% of the total body mass. A normal adult would have approximately 60 to 66 milliliters of blood per kilogram within their body weight. This meant that the heavier the person, the more blood could be found in the body, however 60 to 66 milliliters is really nothing in size of volume. The Doctor learned that the average human being would have approximately 4.5 to 5 liters of blood within their body. Adult males tend to have more, averaging around 5.7 liters while females would average at around 4.3 liters. Thus at lower weights children tended to have lower counts of blood circulating through their body.
