👉 Produces fluid, commonly known as saliva, is a vital bodily secretion produced by the salivary glands located throughout the mouth and throat. Composed primarily of water, along with electrolytes like sodium, potassium, and bicarbonate, as well as enzymes such as amylase that initiate the digestion of carbohydrates, saliva plays a crucial role in maintaining oral health and facilitating speech and swallowing. It also helps to neutralize acids produced by bacteria, thereby protecting teeth from decay, and keeps the oral cavity moist.
