If blood platelets are low, which problem may increase after an injury?
Answer and explanation
Correct answer: Bleeding will stop late
Platelets are cell fragments that gather at an injured blood vessel and help initiate clot formation. The clot creates a temporary seal, reducing blood loss until repair proceeds. If platelet numbers are low, the clotting response may be slower or weaker, so bleeding can continue for longer after an injury. Therefore option A is correct; platelets do not transport oxygen or perform the processes in the other options.
