B) injured tissues and platelets.
C) red blood cells in the area.
D) fibroblasts in the vicinity of the broken blood vessel.

Blood Clotting Cascade

A series of biochemical events that lead to the formation of a blood clot, involving the activation of clotting factors and platelets.

Injured Tissues

Body tissues that have been damaged due to injury, leading to inflammation, pain, and sometimes loss of function.

Platelets

are small blood cells that play a crucial role in clotting, preventing excessive bleeding when blood vessels are injured.
