Lymphoid Organs
The lymphoid organs include the spleen, tonsils, thymus glands and Peyer’s
patches of the intestine. There is commonality between each of these organs:
namely, a high proportion of reticular CT and lymphocytes. The lymphoid
organs contain the phagocytes and lymphocytes, which are crucial for the
immune system to work in full vigor (Marieb 2003).
Organ Types and Functions
Peyer’s patches
Peyer’s patches are a little like tonsils in appearance. They are embedded in the
wall of the small intestine, placing associated macrophages in the perfect
position to capture and destroy bacteria in the intestine.
Peyer’s patches and the tonsils are just one part of the smaller lymph tissues
known as mucosa-associated lymphatic tissue (MALT) (Marieb 2003). MALT
works as a sentinel, protecting the digestive tract and the upper respiratory
system from the constant barrage of foreign matter that enters these cavities.
