@eduscope.labs: This is large intestine tissue, shown at 40x, 100x, and 200x total magnification. Those finger-like folds lining the surface are called crypts. They're deep pits that increase the surface area of the intestinal lining. Look closely at the crypts and you'll spot small circular openings packed along them. Those are goblet cells, and their only job is making mucus, which coats the intestine and helps everything move through smoothly. Unlike the small intestine, the large intestine doesn't have finger-like villi for absorbing nutrients. Its main jobs are absorbing water and forming stool, so under a microscope it looks noticeably different from its neighbor upstream. #biology #microscope #EduTok #Science #histology
