What is the function of the different components of blood?

red blood cell:

white blood cell:

platelet:

plasma:

Red blood cells: These carry oxygen to systemic body cells. If there is more of them, then there is a higher blood oxygen carrying capacity. They will also transport carbon dioxide out of the body.

White blood cells: These are immune system cells, such as leukocytes. One type of leukocyte is a neutrophil. They help fight off bacterial infections. If there is a high neutrophil count, then it indicates that there is likely to be a bacterial infection present.

Platelet: These are cell fragments. They have no cellular functions. However, they help with the process of blood clotting (coagulation, etc.).

Plasma: This is the liquid portion of the blood. It carries the formed elements.
