I know about the highly folded mucosa that's arranged in villi, although I'm unsure whether this is the gut structure? Or whether it's something else?
Any help is greatly appreciated! If you could give the basic idea of it, and then I can investigate into the details myself
I just was unsure whether what I knew was even related to the gut structure!
Thank you in advance!

There's different parts of the intestine:
1. Duodenum
2. Jegunum
3. Ileum
In terms of histology, duodenum is the only part of the small intestine that has submucosal mucus gland (Brunner gland). It otherwise it follows a typical pattern of a small bowel or a gastrointestinal organ of any type. You have quite a delicate finger like papillary array of mucosal villi, lots of loose connective tissue cells & inflammatory cells between those columnar glandular epithelium. You can also see both absorption cells, mucus cells and goblet cells. There's also a lamina propria (loose connective tissues). A thin rim of muscularis mucosa, this is the submucosa, rich in mucus glands as well as some loose connective tissue & blood vessels.

One of the specific features of cells lining the small intestine is that they have a brush border of small bristle-like structures called microvilli (you might have studied them). These microvilli greatly increase the SA for absorption of nutrients. Furthermore, these cells have a portion facing the gut lumen: this has specific protein transporters and enzyme systems that help to uptake and digest the food stuffs that are eaten.
If you could specify what exactly you need to know about the gut, that would be better
