MALT (mucosa-associated lymphoid tissue)

MALT, or mucosa-associated lymphoid tissue, is a specialized part of your immune system located in various mucous membranes lining areas like the stomach, intestines, and respiratory tract. It acts as a surveillance network that detects and fights pathogens—germs like bacteria and viruses—that enter your body through these surfaces. MALT contains immune cells that can quickly respond to infections, helping to prevent illnesses. Think of it as a local security system stationed at common entry points of your body, providing protection while allowing beneficial substances to pass through.
