In general, there are 3 types of bleeding: arterial, venous, and capillary.

shock resulting from blood loss. bleeding from capillaries,which is characterized by a slow,oozing flow of blood. venous bleeding. bleeding from a vein,which is characterized by dark red or maroon blood and a steady,easy-to-control flow.

Venous bleeding distinctions are: The blood is dark red, not bright like arterial bleeding. The blood flow is steady but not spurting; it can still be quick, though. The pressure is lower than arterial bleeding so it’s usually easier to control.

Venous blood is dark red or maroon due to its poor oxygen content. The most common type of bleeding, is slow often oozes from the wound, clots easily, and usually is a paler red than arterial blood. the escape of blood from arteries, capillaries, or veins into spaces in the body, less obvious than external bleeding.

The most severe type of bleeding is arterial bleeding, but venous bleeding can be just as serious. You can identify venous bleeding by looking at the blood’s color and how quickly it flows out of a wound.

For one thing, the dead normally can’t bleed for very long. Livor mortis, when blood settles to the lowest part of the body, begins soon after death, and the blood is “set” within about six hours, says A.J. Scudiere, a forensic scientist and novelist.

Its onset is variable but it is usually most evident about 2 hours after death, although it is stated to occur as soon as 15 minutes after death (Clark et al., 1997). Initially the color is red but it later becomes purple as oxygen dissociates from the hemoglobin, changing it to purple-colored deoxyhemoglobin.
