Blood contains three main types of cellular components: red blood cells for oxygen transport, white blood cells for immune defense, and platelets for blood clotting. Each cell type has specialized structures and functions that are essential for maintaining life.

🔬 Cellular Components

Red blood cells (erythrocytes): 4.5-5.5 million/μL
White blood cells (leukocytes): 4,000-11,000/μL
Platelets (thrombocytes): 150,000-450,000/μL
Plasma: liquid matrix containing proteins & nutrients
Hematocrit: percentage of blood volume as cells (40-45%)

Blood Cell Facts!

You produce about 2.4 million new red blood cells every second! That's over 200 billion new cells each day.
