2. Grinding of Food
When the food is within the mouth area, it's exposed to the grinding activity. Teeth, lips and tongue all participate in the bodily and speedy breakdown of food into smaller portions. Enzymes can quickly work on smaller meal particles.
The procedure for digestion and lubrication begins since the food has been broken down to smaller portions. Three pairs of these salivary glands secrete saliva that has three components:
1. Water and mucus
2. Sodium bicarbonate along with other additives
3. Enzyme–Amylase or ptyalin
Water and mucus
Water and mucus collectively make slimy liquid that mostly moistens and lubricates the food that is eaten. The meals could be chewed economically to permit the digestive juices to go into the food bulk.
Sodium bicarbonate and other additives stabilize the pH of the meals even though they're slightly antiseptic. Fresh saliva is alkaline with a pH 8 but rapidly loses carbon dioxide also has to pH 6.
Amylase (Ptyalin) is a carbohydrate receptor that hydrolyzes glycogen and starch to maltose. Thus softened, partly digested food is currently arranged into little oral bumps called boluses.
