Final answer:
The answer to the question is D. Capillary bleeding, which occurs when the smallest blood vessels called capillaries are damaged, resulting in typically slow and less profuse external bleeding.
Step-by-step explanation:
The question asks which one of the following is a type of external bleeding, and the answer is D. Capillary bleeding. External bleeding can be classified by the type of blood vessel affected: arteries, veins, or capillaries. Capillary bleeding occurs when the capillaries, the smallest blood vessels in the body, are damaged. It is usually slow and not as profuse as arterial or venous bleeding. As part of the body's response to injury, the hemostatic mechanisms initiate a process to stop blood flow to prevent excessive hemorrhage. Hemorrhage refers to a significant loss of blood that exceeds the body's capacity to manage through normal clotting mechanisms, and medical intervention may be necessary to restore blood volume.
