entrance to the digestive and respiratory tracts. The mouth, or oral cavity, is ordinarily a simple opening in lower animals; in vertebrates it is a more complex structure. In humans, the mouth is defined in front and at the sides by the lips, jawbone, teethteeth,
hard, calcified structures embedded in the bone of the jaws of vertebrates that perform the primary function of mastication. Humans and most other mammals have a temporary set of teeth, the deciduous, or milk, teeth; in humans, they usually erupt between the 6th and 24th

, and gums; in the rear it merges with the throat. The roof of the mouth is composed of the hard and soft palatespalate
, roof of the mouth. The front part, known as the hard palate, formed by the upper maxillary bones and the palatine bones, separates the mouth from the nasal cavity. It is composed of a bone plate covered with a layer of mucous membrane tissue.

 and the floor of the mouth is formed by the tonguetongue,
muscular organ occupying the floor of the mouth in vertebrates. In some animals, such as lizards, anteaters, and frogs, it serves a food-gathering function. In humans, the tongue functions principally in chewing, swallowing, and speaking.

, a muscular structure that contains the organs of taste (taste buds). The lips, palates, tongue, and teeth are the major components in speech formation, using the "raw sound" formed in the larynxlarynx
, organ of voice in mammals. Commonly known as the voice box, the larynx is a tubular chamber about 2 in. (5 cm) high, consisting of walls of cartilage bound by ligaments and membranes, and moved by muscles. The human larynx extends from the trachea, or windpipe.

. The process of digestion begins in the mouth; the chewing and grinding action of the teeth reduces the food to a readily digestible substance. The enzymatic process of converting starch to sugar is initiated by salivary amylase (ptyalin) excreted by the three salivary glandssalivary glands
, in humans, three pairs of glands that secrete the alkaline digestive fluid, saliva, into the mouth. Most animals have salivary glands that resemble those in humans; however, in some animals these glands perform other functions.

in the animal kingdom, a group of organs functioning in digestion and assimilation of food and elimination of wastes. Virtually all animals have a digestive system. In the vertebrates (phylum Chordata, subphylum Vertebrata) the digestive system is very complex.

the part of a river that empties into a sea, lake, or another river. In rivers that dry out in their lower course, the place where the river terminates is designated the mouth.

Several types of mouth are distinguished. A simple mouth refers to the terminus of a river that does not divide into branches, such as the Tiber. Rivers may also terminate in deltas, as in the Nile; estuaries, as in the Thames; or limans, as in the Iuzhnyi Bug. A river may end in a discordant junction, which is characteristic of the tributaries of mountain rivers in which downcutting has been less intensive than in the principal river. If a river does not transport its waters to a sea, lake, or another river, it is sometimes said to terminate in a blind end.

Most large rivers that empty into a sea or large lake contain bars at the mouth; farther upriver are deep reaches that provide the customary wintering places for fish, such as the fish preserve pools in the Volga delta. The hydrological regime of river mouths is characterized by a complex variation in flow velocities, caused by such factors as ebb and flow, surge, increased flow rate during high water (ocean and lake rivers), and ice jams formed by drifting ice.
