Assertion (A): Peyer's patches are important structures of the lymphatic system.
Reason (R): Peyer's patches are clusters of lymphoid follicles found in the lining of the small intestine and play a crucial role in the immune response against pathogens.
Both Assertion (A) and Reason (R) are the true and Reason (R) is a correct explanation of Assertion (A).
Both Assertion (A) and Reason (R) are the true but Reason (R) is not a correct explanation of Assertion (A).
Assertion (A) is true and Reason (R) is false.
Assertion (A) is false and Reason (R) is true.
Peyer's patches are an essential part of the lymphatic system as they help to monitor the intestinal contents for the presence of harmful microorganisms and trigger an immune response to protect against infection.
The patches contain specialized immune cells, such as B cells, T cells, and dendritic cells, that recognize and respond to foreign antigens. Thus, the presence of Peyer's patches in the small intestine is critical for maintaining the body's overall immune defense.
Hence, the correct answer is option 1.
