Question

Define MALT and give specific examples and their locations.

Answer 1

Mucosa-associated Lymphoid Tissue (MALT) consists of lymphoid follicles associated with mucous membranes in various parts of the body. One specific example is Peyer's patches in the small intestine. MALT serves important roles in immune responses against ingested substances.

Step-by-step explanation:

MALT consists of lymphoid follicles associated with mucous membranes in various parts of the body. One example of MALT is Peyer's patches, which are found in the small intestine. Peyer's patches are important for immune responses against ingested substances. They contain specialized cells called M cells that sample material from the intestinal lumen and transport it to nearby follicles for immune responses.

Locations of MALT in the body:

1. Intestinal MALT: Found in the lamina propria of the small intestine mucosa, including Peyer's patches in the distal ileum.
2. Gastrointestinal MALT: Found in the mucosa of the gastrointestinal tract.
3. Respiratory MALT: Found in the mucosa of the respiratory tract.
4. Urogenital MALT: Found in the mucosa of the urogenital tract.
5. Others: MALT can also be found in breast tissue and eyes.
