उत्तर
MALT (Mucosa-Associated Lymphoid Tissue) is a collective term for secondary lymphoid tissues found in mucosal linings. It comprises three components: GALT (Gut-Associated Lymphoid Tissue) in the gastrointestinal tract, BALT (Bronchus-Associated Lymphoid Tissue) in the respiratory tract, and NALT (Nose-Associated Lymphoid Tissue) in the nasal passages. Together, these tissues form an interconnected immune defense system protecting entry points into the body.
