Short Answer
The four main components of blood are red blood cells, white blood cells, platelets, and plasma. Each performs a different function in keeping the body healthy.
Detailed Explanation
Blood is much more than a red liquid. It is made up of several specialized components.
Red Blood Cells
Carry oxygen to every part of the body.
White Blood Cells
Protect the body by fighting bacteria, viruses, and other infections.
Platelets
Help blood clot and prevent excessive bleeding.
Plasma
Carries blood cells, nutrients, proteins, hormones, and antibodies throughout the body.
After donation, blood banks usually separate these components so each can help different patients.
Quick Facts
• Each component has a different medical use.
• Patients often receive only the component they need.
• Component therapy helps use every donation more efficiently.
