Shopping Tips. First thing's first: Renting a pressure washer, rather than buying, is an option that allows you to skip the hassle of upkeep and storage. Buying a unit will pay for itself in a few years, as long as you take care of it. If you need to use soaps, solvents or other additives, consider one that has a built-in soap tank.
The pancreas does not have a connective tissue capsule but is covered by loose vascular connective tissue of the mesenteries. Connective tissue septa divide the pancreas into lobes and lobules. The pancreas contains both exocrine (serous acini) and endocrine (islets of Langerhans) components.
A small proportion (1-2 per cent) of the pancreas is made up of other types of cells called islets of Langerhans. These cells sit in tiny groups, like small islands, scattered throughout the tissue of the pancreas. The islets of Langerhans contain alpha cells which secrete glucagon and beta cells which secrete insulin.
