The most prominent throat glands are, thyroid and parathyroid glands, salivary glands and tonsils. Swollen glands in throat indicates several problems and diseases of the throat.

Lymph Glands

Lymph glands or lymph nodes are small cell clusters present in the lymphatic system and are important throat glands. They are between 500 and 600 in number and are present throughout the human body but mostly concentrated in neck, groin and underarms. Lymph is the fluid present between the cells which travels through the lymph channels formed by adjoining lymph nodes. Lymph and lymph glands is an essential part of the immune system as they defend the body against infection. It consists of white blood cells and antibodies which protects the body against foreign particles. The enlarged size of these lymph glands, which we term as swollen throat glands, are extremely important to determine other medical conditions and their causes. So these enlarged throat glands signal an infection.

Thyroid and Parathyroid Glands

The second type of throat glands are the thyroid glands and parathyroid glands. Thyroid glands are two lateral lobes in the shape of a butterfly and are brownish-red in color. Four small bodies protruding from the thyroid glands are called the parathyroid glands. The function of thyroid glands is to regulate body functions like metabolism, appetite, temperature. It also controls lipolysis, protein synthesis and cholesterol levels and helps in the conversion of nutrients to energy. Parathyroid glands regulates the calcium level in the blood and helps in the food absorption by the intestines.

Salivary Glands

Salivary glands secretes saliva that contains water along with mucus, electrolytes and enzymes. There are three types of salivary glands namely parotid glands, submaxillary (mandibular) glands, sublingual glands, depending on the type of secretion. It forms an important part of throat glands due to its various functions. Saliva lubricates the oral cavity and esophagus, helping the food to slide down. It also dissolves dry food and helps maintain oral hygiene by flushing away the food debris that remains in the mouth.

Tonsils are lymphatic tissue shaped like an almond located on both sides of the throat. Usually active in children, they are an important part of the immune system, as they protect the body against bacteria, virus and antibodies.
