Peyer's patches are collections of lymphatic tissue found in the submucosa of the small intestine. Parietal cells secrete hydrochloric acid in the stomach, villi are finger-like projections on the surface of the small intestine that increase surface area for absorption, and enteroendocrine cells secrete hormones for digestion and metabolism.
