External bleeding is generally described in terms of the origin of the blood flow by vessel type. The basic categories of external bleeding are: Arterial bleeding: As the name suggests, blood flow originating in an artery. With this type of bleeding, the blood is typically bright red to yellowish in colour, due to the high degree of oxygenation.
Blood squirt (blood spurt, blood spray, blood gush, or blood jet) is a projectile expulsion of blood when an artery is ruptured. Blood pressure causes the blood to bleed out at a rapid, intermittent rate in a spray or jet, coinciding with the pulse, rather than the slower, but steady flow of venous bleeding.
In biology, hemostasis or haemostasis is a process to prevent and stop bleeding, meaning to keep blood within a damaged blood vessel (the opposite of hemostasis is hemorrhage). It is the first stage of wound healing. Hemostasis involves three major steps: vasoconstriction; temporary blockage of a hole in a damaged blood vessel by a platelet plug
