Answers (1)
This assertion-reason is incorrect. Peyer's patches are not more abundant in the large intestine than in the small intestine. In fact, Peyer's patches are found mainly in the ileum region of the small intestine and are relatively sparse in the large intestine. Moreover, Peyer's patches are not involved in the absorption of nutrients from the digested food. Instead, they are responsible for the initiation and modulation of immune responses in the intestine.
Peyer's patches are clusters of lymphoid follicles found in the mucosa of the small intestine, particularly in the ileum region. They are a type of lymphoid tissue and are important for immune surveillance and defense against pathogens. Peyer's patches contain various immune cells, such as T cells, B cells, and macrophages, which detect and respond to invading pathogens and antigens.
The absorption of nutrients from digested food occurs mainly in the small intestine, but it is not a function of Peyer's patches. Instead, the epithelial cells that line the intestinal villi are responsible for nutrient absorption, aided by various digestive enzymes and other factors secreted by the pancreas and other organs.
Option 4 is the correct answer.
