Explanation:

Each blood component has a distinct core function:

1. White blood cells are part of the immune system and fight bacterial infections.
2. Red blood cells contain hemoglobin, which binds and transports oxygen throughout the body.
3. Platelets trigger the clotting cascade to stop bleeding from damaged vessels.
4. Plasma is the liquid matrix of blood, and its composition gives blood its viscosity.

Answer:

• fighting bacteria → white blood cells
• transporting oxygen → red blood cells
• clotting blood → platelets
• providing viscosity to the blood → plasma
