Where is malt tissue located?

The mucosa-associated lymphoid tissue (MALT), also called mucosa-associated lymphatic tissue, is a diffuse system of small concentrations of lymphoid tissue found in various submucosal membrane sites of the body, such as the gastrointestinal tract, nasopharynx, thyroid, breast, lung, salivary glands, eye, and skin.

Is MALT found in the spleen?

These include: lymph nodes, tonsils, spleen, Peyer’s patches and mucosa associated lymphoid tissue (MALT).

What is MALT tissue?

The mucosa-associated lymphoid tissue (MALT) initiates immune responses to specific antigens encountered along all mucosal surfaces. MALT inductive sites are secondary immune tissues where antigen sampling occurs and immune responses are initiated.

Lymph nodes are located in many parts of the body, including the neck, armpit, chest, abdomen (belly), and groin.

MALT (mucosa-associated lymphoid tissue) is lymphoid tissue found in the mucosa of the digestive, respiratory, and genitourinary tracts. It includes tonsils, Peyer’s patches, and the appendix.

Where is the thymus gland located?

The thymus gland is in the chest between the lungs. It makes white blood cells (T lymphocytes) which are part of the immune system and help fight infection. The thymus gland is in the chest, between the lungs and behind the breastbone (sternum). It is just in front of, and above, the heart.
