This section is from a human submandibular gland. At the lowest magnification you can see the septa of connective tissue dividing the gland into lobules. As all the other salivary glands, the submandibular gland is a merocrine gland which means that its cells secrete liquid without themselves being changed or destroyed. Other secretion mechanisms are apocrine and holocrine.
