Mark the following statements as true or false. If a statement is false, correct it to make a true statement.




e. Clusters of MALT located around the oral and nasal cavities are known as Peyer's patches.

Verified step by step guidance

1. Understand the term MALT: Mucosa-associated lymphoid tissue (MALT) is a collection of lymphoid tissues that protect the mucous membranes lining the digestive, respiratory, and urogenital tracts.
2. Identify the location of Peyer's patches: Peyer's patches are specific clusters of lymphoid tissue found in the ileum of the small intestine, not around the oral and nasal cavities.
3. Recognize the correct term for clusters of MALT around the oral and nasal cavities: These are typically referred to as tonsils, which include the palatine tonsils, lingual tonsils, and pharyngeal tonsils (adenoids).
4. Evaluate the statement: The statement is false because Peyer's patches are not located around the oral and nasal cavities.
5. Correct the statement: Clusters of MALT located around the oral and nasal cavities are known as tonsils, not Peyer's patches.

Key Concepts

MALT (Mucosa-Associated Lymphoid Tissue)

MALT refers to a collection of lymphoid tissues found in mucosal sites throughout the body, including the gastrointestinal tract, respiratory tract, and urogenital tract. It plays a crucial role in the immune response by protecting mucosal surfaces from pathogens. MALT includes structures such as tonsils, adenoids, and Peyer's patches, which are specifically located in the intestines.

Peyer's Patches

Peyer's patches are specialized lymphoid follicles located in the ileum, the last part of the small intestine. They are part of the gut-associated lymphoid tissue (GALT) and are essential for monitoring intestinal bacteria and preventing the growth of pathogenic bacteria in the intestines. Unlike MALT clusters in the oral and nasal cavities, Peyer's patches are specifically associated with the gut.

Immune System Function

The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful pathogens. It includes both innate and adaptive immunity, with MALT playing a significant role in the adaptive immune response by generating specific immune reactions to antigens encountered at mucosal surfaces. Understanding the function of MALT is essential for recognizing how the body protects itself from infections.
