Final answer:
Arterial bleeding is characterized by bright red blood that spurts from a wound, indicating severe bleeding, and is part of the body's critical response to skin injury leading to clot formation.
Step-by-step explanation:
Arterial bleeding is usually bright red and spurts from the wound. This is one of the easily recognizable signals of severe bleeding. When an injury occurs and a blood vessel is severed, blood and blood components such as erythrocytes (red blood cells) and white blood cells begin to leak out of the breaks in the vessel. In the event of a skin injury, the body initiates a wound-healing response where the first step is the formation of a blood clot to stop bleeding. Following this, hemostasis occurs which includes three steps: vascular spasm, the formation of a platelet plug, and coagulation (blood clotting).
