Answers
Answer:
Explanation:
Saliva is an extracellular fluid produced and secreted by salivary glands in the mouth. In humans, saliva is 99.5% water plus electrolytes, mucus, white blood cells, epithelial cells, enzymes, antimicrobial agents such as secretory IgA, and lysozymes.
Moistens and lubricates the oral cavity and the tongue to make speaking and swallowing easy. Acts as a solvent, dissolving some part of food to stimulate taste. Cleans the mouth and destroys germs.
Answer:
Saliva makes many normal, everyday activities possible, thanks to its unique composition. Without saliva stimulating your taste buds, you'd miss out on the experience of a delicious meal. Plus, chewing and swallowing would be not only difficult — but dangerous. So, what is saliva made of and why is it so important?
