Light micrograph of normal human pancreas. The pancreas secretes both as an exocrine gland (digestive juice) and as an endocrine gland (insulin and blood regulatory substances). In this picture the exocrine tissue, consisting of serous acini, is stained orange with crimson nuclei. The paler area, top left of centre, is an Islet of Langherhans, the site of endocrine secretions such as insulin and glucagon. The channel filled with small red particles (blood cells), to bottom right corner, is a blood vessel; visible next to it is fibrous connective tissue (wavy blue lines). Magnification: x50 at 35mm size.
