Which type of blood cell is primarily responsible for clotting?

• A. Red blood cells
• B. White blood cells
• C. Platelets
• D. Plasma

Answer: (C)

Platelets are the type of blood cell primarily responsible for clotting. When a blood vessel is injured, platelets quickly gather at the site of the injury, adhering to the exposed tissue and each other, forming a temporary "plug" that helps stop the bleeding. This process is crucial for wound healing and maintaining bodily integrity after an injury. Platelets, also known as thrombocytes, play a key role in hemostasis, which is the cessation of blood loss from a damaged vessel. They contain chemicals that promote further clotting and facilitate the aggregation of more platelets, ultimately leading to the formation of a stable clot. Other components of blood, such as red blood cells, white blood cells, and plasma, do not carry out the function of clotting. Red blood cells are primarily responsible for transporting oxygen and carbon dioxide. White blood cells play a vital role in the immune response, helping to protect the body against infections. Plasma is the liquid component of blood that carries cells, nutrients, hormones, and waste products but does not contribute to the clotting process. Therefore, platelets are specifically suited to the task of initiating and driving the clotting process.
