how deer die
Lets talk a little about how deer die when hit by an arrow in the rib cage. Three ways will cause a deer to lie down within 100 yards and die within 30 min. First, a direct hit to the heart aorta vena cava or major blood vessel this will cause an immediate drop in blood pressure also known asHypovolemic shock. Next, ismechanical shock this iswhen a hole is created in the chest wall causingatension pneumo-thorax basically when air is trapped around the lung and will not let the lung expand. You will also see this when the chest wound has sealed off.Another type of injury is ahemothorax when blood is trapped around the lungs and will not let them expand. Times when this may be seen is when youopen the chest cavity and liters of blood come rushing fromthe first cut into the diaphragm.None of these injuries require a direct hit tothe lungs to cause a quick death. Last is mass lung tissue damage this causes a lack of ability to diffuse air into the blood and then perfuse the body. With this type of trauma it helps to hit close to the bronchial bifurcations this will cause all of theinferior lung tissueto be useless. This is howthe death process takes place, a combination ofall three is the most common. If I need to explain myself anymore just ask. P.S. the void that everyone is talking about is where the aorta and vena cava are located.
