Bleeding in general is a condition that involves losing blood. This can occur internally (when blood leaks from blood vessels inside the body), externally through a natural opening. When the bleeding comes from a vein, then it is a venous bleeding; on the other hand, if the bleeding comes from an artery, it is arterial bleeding. Veins are different than arteries. In fact, inside our body, there are different kinds of vessels that transport the blood through it; a vein is one of those, and it carries blood toward the heart. Most veins have one-way valves called venous valves to prevent backflow caused by gravity. They also have a thick collagen outer layer, which helps maintain blood pressure and stop blood pooling. A venous bleeding is not as dangerous and dramatic as arterial bleeding.
The arteries are the vessels that carry blood away from the heart; they are muscular, elastic tubes that transport blood under the pressure of the hearts pumping action. Because the arteries are absolutely related to the bodys pressure, their bleeding is extremely dangerous. In my opinion, this is the main difference between venous and arterial bleeding; arterial bleeding is a deadly bleeding because it carries blood under the pressure of the hearts action.
