Introduction to Immunology

An image that depics how the immune system protects us against pathogens

Immunology is the study of the body's defence against infection. Despite constant exposure to pathogenic microorganisms, including viruses, bacteria, and fungi, our bodies often successfully ward off illnesses. This protection is achieved through the intricate immune defences that detect and eliminate both external and internal threats, ranging from infected cells to cancerous ones.

Key Components of the Immune System

Major Components Image consisting of Whiteblood cell, antibody, and the Lymphatic System blood vessels.

[Left] White Blood Cells (Leukocytes): These are the soldiers of the immune system, patrolling the bloodstream and tissues to identify and eliminate invaders.
[Middle] Antibodies: Y-shaped proteins produced by the immune system to recognise and neutralise specific pathogens.
[Right] Lymphatic System: A network of vessels, nodes, and organs (like the spleen and thymus) that transport immune cells and fluids all throughout the body.

How the Immune System Works

When a pathogen enters the body, the immune system mounts a defense. White blood cells identify the invader, antibodies neutralise it, and specialised cells remember the encounter to provide a faster response in the future. This orchestrated defense is essential for preventing infections and maintaining overall well-being.
