Saliva is a fluid produced and secreted by the salivary glands. It is composed of water, mucous, and enzymes. Saliva helps digestion by moistening the food (a physical change), and breaking down starches in the foods with its enzymes (a chemical change).
There are three main types of saliva: serous saliva, mucous saliva, and mixed saliva. Serous saliva is watery and contains enzymes that help break down food. Mucous saliva is thicker and helps lubricate food for easier swallowing. Mixed saliva is a combination of both serous and mucous saliva, which aids in digestion and protects the mouth.
The mouth, specifically the teeth, grinds the food into smaller pieces with the help of saliva containing enzymes that begin the digestion process.
Saliva contains the enzyme amylase, which is used in the first step of digestion to break down carbohydrates into simpler sugars.
Saliva is primarily responsible for the digestion of carbohydrates in the form of starches. Salivary amylase is an enzyme in saliva that helps break down starch molecules into simpler sugars like maltose.
The salivary gland produces an important digestive enzyme, called amylase, that helps to break down starches and liquefy the food in the chewing phase of digestion. Once swallowed, the food is exposed to more enzymes and processes that complete the digestion as it travels through the various areas of the digestive tract.
saliva is the substance in the mouth that contains enzymes to help with digestion before the food is swallowed.

No, saliva does not contain hydrochloric acid. Saliva is a watery fluid that is produced by the salivary glands in the mouth to help with chewing, swallowing, and digestion. Hydrochloric acid is produced in the stomach as a component of gastric juices to aid in the digestion of food.
Yes, it does. In fact, saliva is used to begin the digestion process in foods like carbohydrates.
Saliva is slimy because it contains mucins, which are proteins that help lubricate and protect the mouth and aid in digestion. The sliminess of saliva helps with swallowing and keeps the mouth moist.
A dog has saliva around its mouth to help with digestion and to keep its mouth moist. Saliva also helps to break down food and make it easier to swallow.
Yes, proteases are found in saliva. They help in breaking down proteins into smaller peptides and amino acids during the initial stages of digestion in the mouth. This process is essential for the digestion and absorption of proteins in the body.
Teeth help by mechanical digestion, which is breaking the food in smaller pieces in order for the saliva to cover it and make it easier to digest.
A dog's mouth produces thick saliva to help with the digestion of food and to keep the mouth moist for better tasting and swallowing.
Saliva is used to start the digestion process.
