Scenario:A 45-year-old patient comes to the clinic with complaints of poor nutrient absorption, bloating, and frequent diarrhea. The doctor explains that the inner lining of the small intestine has specialized tissues that increase surface area for absorption and secrete digestive enzymes. A biopsy of the intestinal wall shows finger-like projections with a single layer of tall cells, and scattered mucus-secreting cells between them. Question:Which types of tissue are primarily responsible for nutrient absorption and mucus secretion in the small intestine? Options:A. Stratified squamous epithelium and adipose tissueB. Simple columnar epithelium with goblet cellsC. Transitional epithelium and smooth muscleD. Pseudostratified ciliated epithelium with serous glands
