Which of the following is NOT a type of bleeding?

Tissue is not classified as a type of bleeding. In medical terminology, the three primary types of bleeding are arterial, venous, and capillary, each defined by the type of blood vessel from which the blood is lost.

Arterial bleeding refers to blood that is expelled from an artery, characterized by a bright red color and a pulsing flow, as it is under high pressure. This type of bleeding can be quite serious, often requiring immediate medical attention due to its rapid volume loss.

Venous bleeding, on the other hand, involves blood flowing from a vein. This type generally has a darker red color and flows more steadily rather than in spurts, as veins are under lower pressure compared to arteries.

Capillary bleeding is the slow oozing of blood from capillaries, the smallest blood vessels in the body. This can happen with minor cuts or scratches and is typically easier to control than arterial or venous bleeding.

Tissue does not play a role in these classifications of blood loss and instead refers to the biological material that forms the structure of organs and body components. Thus, identifying tissue as a type of bleeding is inaccurate, making it the correct answer in this context.
