Verified step by step guidance

Understand the function of each blood component: Plasma is the liquid portion that carries cells and nutrients; Red blood cells transport oxygen; White blood cells are involved in immune response; Platelets are cell fragments that play a key role in blood clotting.

Recognize that blood clotting is a process that prevents excessive bleeding when a blood vessel is injured.

Identify that platelets are the primary component involved in the clotting process. They adhere to the site of injury and release chemicals that activate clotting factors.

Learn that clotting factors are proteins in the blood plasma that work with platelets to form a stable clot.

Conclude that while plasma contains clotting factors, platelets are the main component that initiates the clotting process by forming a plug at the injury site.
