The next set of things the Doctor had to learn when trying to understand the concept of Blood Spatter Analysis was the rate of bleeding. This was the volume of blood loss from the inside of a circulation system per unit of time whether it is external or internal or even both. This was determined by the type of vessel that was bleeding such as the arterial, venous, or capillary. It also depended on the diameter of the vessel as well as the pressure of the blood found in the vessel.
This is of importance in determining the rate of bleeding found within the lesion of the vessel. Since the Doctor was, well a Doctor he knew that this was important since arteries have smooth muscle making up a part of the blood vessel wall. Because of this, the Doctor knew that a completely transected artery would always bleed less than an artery that was partially transected. If a blood vessel was completely transection the vessel would retract because of the contraction of the muscle wall, and the partial cuts off the flow of blood. Then there was the partial transection which was a vessel that could not retract. There was little reduction in the size of the hole and the rate of bleeding.
With these concepts the Doctor knew that physical trauma or damage to the arteries would produce significant and event frequent fatal consequences due to blood being released rapidly under pressure. This type of trauma was frequently associated with cutting and stabbing injuries but may also occur through blunt force and especially through gunshot injuries. These locations of breached arteries normally dictate whether there was excessive internal bleeding or external bloodshed will occur. The Doctor learned that severe internal bleeding within the abdominal cavity occurs when the aorta is damaged. He also learned that when it came to external bleeding it may not look as severe.
This is where he learned that any artery closer to the surface of the body that was damaged would release blood under pressure to the external environment would result in gushing or spurting. Either way the blood would continue to surge from the damaged artery so long as the heart continues to pump and as long as there is available blood found in the body. With this knowledge the Doctor knew that medical intervention was critical for survival.
There were several arteries the Doctor had to learn for the course of Blood Spatter Analysis and the course of becoming a medical Doctor that were common and close to the surface. Located to the temples was the Temporal Artery while the neck has the carotid artery. The Under Clavicles was the Subclavian artery. The Axilla had well, the Axillary artery. Found on the arms was the Brachial artery while the wrist housed the radial artery. The upper thighs kept the femoral artery, the knees kept the popliteal arteries and the ankles kept the Tibial artery.
To keep the brain maintained with a good blood supply along with the tissues of the body the body needed the blood pressure to be kept above 100/40 mm Hg. The brain is the most sensitive organ of the body to have reduction in blood supply. Oxygen was needed from the circulation of blood as well as the nutrients to the tissues and taking away the carbon dioxide produced by the metabolism of the tissue.
