Document Summary
Identification: small, flat cells arranged around large, empty circles (air sacs). May be confused with adipose tissue, but note the multiple cells and nuclei (arrows). Where located: lung (air sacs or alveoli) and lining blood vessels . The top image is what you would see with a transverse section through the tissues. The bottom image is from a cheek smear and shows a cluster of four cells viewed if they were laid out flat. Identification: squarish cells with round nuclei in a single row (arrows), usually arranged in a circle (tubule). Where located: kidney tubules (can also be seen in sweat glands of skin slide). Identification: tall rectangular cells, with single, neat row of oval nuclei, usually more towards the base (in the bracketed row, the base is towards the top), leaving an apical region of nucleus-free cytoplasm. Note also goblet cells, found only here and in. Features to know: goblet cells (1), nuclei (2), microvilli (3).
