AIIMS 2019 Zoology Epithelial Tissue MCQ Question

The diagram represents glandular epithelium, characterized by specialized cells that produce and secrete substances such as hormones, enzymes, and mucus. This type of epithelium is typically found in glands like the thyroid and salivary glands, where it plays a crucial role in maintaining homeostasis through secretion. In contrast, ciliated epithelium (option B) features hair-like structures that aid in movement of substances, squamous epithelium (option C) consists of flat cells primarily involved in diffusion and filtration, and areolar connective tissue (option D) is a loose connective tissue that supports and binds other tissues rather than secreting substances.
