What term refers to the loss of blood that can occur from injuries and can be external?

• A. Bleeding
• B. Biohazard
• C. Blindness
• D. Bone loss

Answer: (A)

Bleeding is the loss of blood from the circulatory system, and it can be external when blood escapes from a wound and is visible on the outside of the body. This term specifically describes the process of blood leaving the vessels due to injury, which is why it fits the question. The other terms don’t describe blood loss: a biohazard refers to dangerous biological materials, blindness is the loss of sight, and bone loss means reduced bone tissue or density. In practice, recognizing bleeding guides you to respond quickly—apply direct pressure with a clean dressing, cover the wound, and seek medical help as needed to control the loss and prevent shock.
