Function of saliva in the immune system

Collectively, the primary function of these glands is the production and secretion of saliva. The components of saliva are produced by serous and mucous acinar cells within the glands, and saliva is then drained though a network of ducts into the oral cavity. Your immune system works to identify pathogens and tumor cells that could cause disease and to eliminate them from your system. There are two types of immunity innate immunity which we have by birth and the second acquired immunity which we gain during our life.

Saliva is a part if our innate immunity and further comes under the subheading of physiological immunity. The main function of the immune system is to ward off invaders in order to protect the body from infection. In fact, when our bodies have an immune response , our immune systems attack the invaders that can harm our other body systems and cause illness or disease.

Saliva has innate immune functions and many direct interactions between saliva and bacteria have been described previously. We therefore chose to study the interaction between saliva and other components of the innate immune system in the oral cavity. The functions of saliva are: 1. Crucially, it can distinguish our tissue from foreign tissue — self from non-self. Dead and faulty cells are also recognized and cleared away by the immune system.

One function of the immune system is that it creates natural immunity through the body’s own barriers, like the skin, saliva , and mucus in the mouth, urinary tract, and on the surface of the eye. Natural immunity also is created when a mother passes antibodies to her child. In organ transplants, the body recognizes that the new organ is made of foreign cells. Saliva prepares the food for swallowing forming a slippery coat over the bolus.

The Immune System has Lines of Defense Against Foreign Pathogens: 1. The immune system works to defend us against hordes of microorganisms and germs that we are exposed to every day. Physical and Chemical Barriers (Innate Immunity) 2. Nonspecific Resistance (Innate Immunity) 3. Antibodies help the immune system to attack pathogens (organisms that cause disease), while antiseptics kill pathogens directly. Although mucus is important in many places in the body, for most of us its presence is most obvious in the nose and the respiratory tract. Mineral salts in saliva — calcium and phosphate ions — slow demineralization of tooth structure and encourage ongoing re-mineralization of tooth enamel, thus reversing the decay process.

Fostering Healthy Plaque BiofilImmune proteins in saliva regulate the growth, maintenance and movement of healthy plaque biofilm. Microbes and the immune system work together to eliminate and prevent visiting microorganisms from living in the mouth. T-cell number and function. Shedding of viral DNA was quantified in saliva and urine samples, and urine samples were used to measure excretion of stress hormones. Schedule for bloo saliva , and urine collection.

The body produces around 1. This article shall consider the production of saliva , how it varies on consumption of food and the consequences of low secretion. The innate immune system is a non-specific response that includes deterrents like the skin, enzymes in saliva , and inflammatory reactions by immune cells. Invading viruses, bacteria, and other microbes try to invade the body, and the immune system targets them while leaving healthy tissues alone.

There are three main groups of phagocytes: monocytes and macrophages, granulocytes, and dendritic cells, all of which have a slightly different function in the body. They are a key component of the innate immune system. For example, skin is an important part of the immune system.

It acts as a primary boundary between germs and your body. Other than your nervous system, your immune system is the most complex system in your body. It’s made up of tissues, cells, and organs, including: Your tonsils.
