Parotid gland
This higher magnification image shows a group of lobules surrounded by interlobular connective tissue. In the parotid, each of these lobules consists of serous acini and the intralobular duct system. Secretory cells release their thin, watery secretions into a small lumen in the center of the acinus. From there, the fluid drains into intercalated ducts (not visible at this magnification), then intralobular ducts that anastomose to form larger interlobular ducts located in the surrounding connective tissue. 100x
