Saliva is produced in and secreted from salivary glands. The basic secretory units of salivary glands are clusters of cells called an acini. These cells secrete a fluid that contains water, electrolytes, mucus and enzymes, all of which flow out of the acinus into collecting ducts.
Much of the sodium is actively reabsorbed, potassium is secreted, and large quantities of bicarbonate ion are secreted. Bicarbonate secretion is of tremendous importance to ruminants because it, along with phosphate, provides a critical buffer that neutralizes the massive quantities of acid produced in the forestomachs.
The basis for different glands secreting saliva of differing composition can be seen by examining salivary glands histologically. Two basic types of acinar epithelial cells exist:
serous cells, which secrete a watery fluid, essentially devoid of mucus
mucous cells, which produce a very mucus-rich secretion

Yep compaq is right. You have the parotid glands which are on both sides of your face right around the area of the cheek bones--they're pretty large glands. Then on both sides of you lower jaw are the submandibular saliva glands and those lie under the jaw bone kind of right before your jaw curves upward. Then there is the sublingual gland which lies on the floor of the mouth under the tongue. Also there are hundreds of minor salivary glands inside of the mouth. If you run your tongue along the inside of your lips you will feel a bunch of little bumps--those are the minor salivary glands. They are also on the roof of your mouth, in the back on the soft palate, in all of the inner cheek tissues and under your tongue. I hope that answers your question and not the silly remarks from other people.
