Question

question
the digestive tract has an extensive array of lymphoid nodules collectively known as the:
answer
aggregated lymphoid nodules.
malt (mucosa - associated lymphoid tissue).
tonsils.
lymphoid nodules.
diffuse lymphoid tissue.

Explanation:

MALT (mucosa - associated lymphoid tissue) is a collection of lymphoid follicles in the mucosa of various organs, including the digestive tract. Aggregated lymphoid nodules (Peyer's patches) are a part of MALT but are not the collective term for all lymphoid nodules in the digestive tract. Tonsils are located in the throat, not throughout the digestive tract. Lymphoid nodules alone do not refer to the collective array. Diffuse lymphoid tissue is less organized than the structured MALT.

Answer:

MALT (mucosa - associated lymphoid tissue).
