HUMAN NUTRITION

Detailed explanation-1: -Salivary glands, liver and pancreas secrete digestive juices that help in the breakdown of complex food substances into simpler ones. For example, bile secreted from the liver into the small intestine plays an important role in digesting fats. Saliva, which helps in digestion is secreted by the salivary gland.

Detailed explanation-2: -Your pancreas creates natural juices called pancreatic enzymes to break down foods. These juices travel through your pancreas via ducts. They empty into the upper part of your small intestine called the duodenum. Each day, your pancreas makes about 8 ounces of digestive juice filled with enzymes.

Detailed explanation-3: -The saliva is produced in the mouth by the salivary glands. There are three pairs of salivary glands called parotid, submaxillary and sublingual glands which secrete the saliva directly into the mouth. Saliva contains digestive juice called ptyalin.

Detailed explanation-4: -Salivary glands play an important role in digestion because they make saliva. Saliva helps moisten food so we can swallow it more easily. It also has an enzyme called amylase that makes it easier for the stomach to break down starches in food.

Detailed explanation-5: -Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb. Saliva also contains an enzyme called lingual lipase, which breaks down fats.
