Exploring the Anatomy and Function of Canine Salivary Glands

The canine salivary glands are a vital part of a dog's digestive system, playing a crucial role in breaking down food and aiding in the absorption of nutrients.

Located in the mouth, the salivary glands produce saliva that contains enzymes to help digest carbohydrates and proteins.

The major salivary glands in dogs are the parotid, submandibular, and sublingual glands, each with distinct functions and locations in the mouth.

The parotid glands are the largest of the three, producing over 70% of a dog's saliva.

Canine salivary glands are located below the jaw, under the floor of the mouth, and in front of the ears, similar to their human counterparts. They are made up of tissue that encases each gland, consisting of fat and acini (cells that secrete fluids).

The salivary glands in dogs are divided into lobes, lobules, and acini, with ducts connecting them. The ducts are lined by cells that produce saliva. In dogs, the parotid glands are the largest, followed by the submandibular and sublingual glands.

Here's a comparison of the major salivary glands in dogs:

The salivary glands in canines are made up of tissue that encases each gland, with the glands themselves consisting of fat and acini (cells that secrete fluids).

The salivary glands are divided by connective tissue septa into lobes, then lobules, and finally acini with ducts.

Acini are the round secretory units where secretion of saliva occurs.

The salivary ducts are lined by 3 types of cells.

In canines, the salivary glands are connected to the oral cavity through ducts, which open at specific sites on the face and tongue.

The three major salivary glands in dogs are similar to those found in humans, and they play a crucial role in their oral health. These glands produce saliva that helps to break down food and protect their teeth.

The sublingual glands are located below the tongue, under the floor of the mouth. They produce saliva that enters the mouth from under the tongue. Each sublingual gland is about the size of an almond.

The submandibular glands are located below the jaw and consist of two parts: the superficial lobe and the deep lobe. The saliva produced by these glands enters the mouth from under the tongue. Together, the two submandibular glands are about the size of a walnut.

The parotid glands are located in front of the ears and have two parts: superficial and deep. The saliva produced by these glands enters the mouth from small ducts near the upper molars. Each parotid gland is slightly smaller than a dog's ear.
