It is often partitioned into groups separated by connective tissue. Each larger partition of parenchyma, having one or several excretory ducts is called a <strong>lobe<\/strong> (highlighted in a lighte hade of blue in the image).  Large glands are formed by several <strong>lobes<\/strong>. In this section the lobes became artificialle separated during the preparation of the tissue for sectioning.<br \/>\nEach lobe may be be formed by even smaller divisions called <strong>lobules<\/strong>, separated one from another by less connective tissue. Three lobules are highlighted in dark blue in the image.<br \/>\nThe supporting tissue (connective tissue) of the glands, called <strong>stroma<\/strong>, joins the components of the parenchyma and contains blood vessels, lymphatics and nerves. A small layer of stroma surrounds the thin ducts and progressively more connective tissue surrounds the excretory ducts as they enlarge.<br \/>\nA large excretory duct can be seen at the upper right corner of the image.<\/p>\n<\/div><\/div>\n <div class=\"su-column su-column-size-1-2\"><div class=\"su-column-inner su-u-clearfix su-u-trim\">\n<div onclick>\n<div class=\"image-container\">\n<div class=\"extra\">\n<a href=\"javascript:void(0)\"><img decoding=\"async\" src=\" https:\/\/mol-en.icb.usp.br\/wp-content\/uploads\/3-20.jpg \" onmouseover=\"this.src =' https:\/\/mol-en.icb.usp.br\/wp-content\/uploads\/3-20BMO-A.jpg'\" onmouseout=\"this.src=' https:\/\/mol-en.icb.usp.br\/wp-content\/uploads\/3-20.jpg'\" \/><\/a><\/div>\n<p>Parotid.
