Question

Where is Mucosa-Associated Lymphoid Tissue (MALT) primarily located in the body?

Options

• Mucosal linings of the gut, lungs, nose, and throat

• Bones and bone marrow

• Upper chest cavity

• Left upper abdomen

Answer 1

MALT (Mucosa-Associated Lymphoid Tissue) is a secondary lymphoid tissue found in the mucosal linings of the gastrointestinal tract, respiratory tract, and other entry points into the body. It provides defense against pathogens attempting to enter through mucosal surfaces, representing the body's first line of immune defense at these vulnerable sites.
