Pulmonary lobule

"Section of a pulmonary lobule, showing its division into pulmonary vesicles." — Tracy, 1888

Lobules of the liver (1), which are small, granular-looking bodies, of polygonal shape, and about 1/20 inch in diameter, clustered around the sublobular branches of the hepatic veins, and connected together by connective tissue (3), blood-vessels, ducts (2), and lymphatics. Each lobule consists of a mass of hepatic cells, surrounded by a dense capillary plexus, and contains the minute beginnings of a bile-duct, the so-called biliary capillaries; possessing therefore all the essential constituents of a secreting gland. A lobule contains hepatic cells, lobular veins (3), intralobular veins (4), and plexuses of lymphatics, nerves, and bile-ducts.
