external bleeding i belive
arterial bleeding is the most serious type of external bleeding. this type of bleeding can lead to a large amount of blood loss in a short period of time because the blood flows at a faster rate and is less likely to clot.
Platelets are the type of blood cells responsible for helping with blood clotting. They form a plug at the site of a wound to stop bleeding by adhering to the damaged blood vessel walls and releasing chemicals that promote clotting.
Any type of wound can be dangerous an run the risk of infection. The most fatal type of wound is one that has punctured a major organ, or severed a major artery.
Bright red blood spurting from a wound typically indicates that an artery has been severed, resulting in arterial bleeding. This type of bleeding is often more serious than venous bleeding, as it can lead to rapid blood loss and requires immediate medical attention. The bright red color signifies that the blood is oxygen-rich, which is characteristic of arterial blood. Prompt action, such as applying direct pressure and seeking emergency help, is crucial in this situation.
arteries
In a healthy individual blood clots at a wound site to stop bleeding. This process begins with the cells lining the blood vessels causing the clots to form, then proteins create fibrin (which is another type of protein) that acts as glue to hold a blood clot together, and platelets which are small blood cell fragments stick together to form a clot. After the bleeding has stopped and healing has occurred the body breaks down and removes the clot.

Arteries
Frank bleeding is a type of bleeding that can form in the stool. As opposed to "black tarry stool" that is digested stool, frank blood is bright red probably caused by a hemorrhoid or anal fissures. This blood is on the surface of the stool, not digested.
Arteries...especially the femoral or carotid arteries located in the upper thighs and neck respectively.
