The lacrimal gland is a compound tubuloacinar gland, it is made up of many lobules separated by connective tissue, each lobule contains many acini.The acini composed of large serous cells which, produce a watery serous secretion, serous cells are filled with lightly stained secretory granules and surrounded by well-developed myoepithelial cells and a sparse, vascular stroma.
The lacrimal glands secrete lacrimal fluid, which flows through the main excretory ducts into the space between the eyeball and the lids. [10] When the eyes blink, the lacrimal fluid is spread across the surface of the eye. [10] Lacrimal fluid gathers in the lacrimal lake which is found in the medial part of
The lacrimal apparatus is the physiological system containing the orbital structures for tear production and drainage. [1]It consists of: The lacrimal gland, which secretes the tears, and its excretory ducts, which convey the fluid to the surface of the eye; it is a j-shaped serous gland located in lacrimal fossa.

It is a j-shaped gland;
Examples include the salivary glands: although the parotid gland (saliva secretion 25%) is predominantly serous, the sublingual gland (saliva secretion 5%) mainly mucous gland, and the submandibular gland (saliva secretion 70%) is a mixed, mainly serous gland. Sebaceous glands secrete sebum, a lipid product.

Most lacritin is produced by the lacrimal gland, [4] including the accessory lacrimal gland of Wolfring. [10] Some lacritin is produced by the meibomian gland, and by epithelial cells of the conjunctiva and cornea. [11] Together these epithelia comprise much of the lacrimal functional unit (LFU). Dry eye is the most common disease of the LFU.
Lactoperoxidase (LPO, EC. 1.11.1.7) is a peroxidase enzyme secreted from mammary, salivary, tears and other mucosal glands including the lungs, bronchii and nose [5] that function as a natural, first line of defense against bacteria and viral agents. [6] Lactoperoxidase is a member of the heme peroxidase family of enzymes.
