Verified step by step guidance

Understand the function of each blood component: Platelets, Plasma, Red blood cells, and White blood cells.

Platelets are small cell fragments in the blood that are crucial for blood clotting. They gather at the site of a wound and form a plug to stop bleeding.

Plasma is the liquid portion of blood that carries cells and proteins throughout the body. It contains clotting factors but is not primarily responsible for clotting.

Red blood cells are responsible for carrying oxygen from the lungs to the rest of the body and returning carbon dioxide to the lungs for exhalation.

White blood cells are part of the immune system and help fight infections. They do not play a direct role in blood clotting.
