Overview of Blood Components and Immune Response

Plasma is like the chill water in your bloodstream, transporting globulins and waste. Red blood cells, or erythrocytes, are the biconcaved goons carrying oxygen but they are lowkey useless after 120 days. White blood cells, the immune squad, feature B cells making antibodies and T cells that send the sigma signals to fight infections. Antigens are the enemy flags, while antibodies are the Y-shaped locks ready to catch them. The defense squad has three lines: skin is the first wall, inflammation is the goon squad reacting to injuries, and the B/T cells are the ultimate edge, remembering past battles to keep you safe.
