Why is it important to crushing and grinding food?
It is very important because the foods are better absorbed in the small intestine and also eases the work of the stomach because less acid is required to break proteins.
There are four kinds of teeth in the mouth of a human mouth: The INCISORS are the front four teeth in your mouth and they are used for cutting your food. The CANINES are located on either side of the Incisors and are used for tearing and shredding food. The PREMOLARS are the next two teeth on both the left and right side of the canines, and they are used for grinding and crushing food…
Premolars - are transitional teeth located between the canines and the molars at the rear. They have 1 or more cusps (points) and are generally used for grinding and crushing. But they may also be used in slicing food. Molars- have many major cusps (e.g., 3-5) and are located in the back of the mouth on the cheek side. Molars function in grinding and crushing.
Quartzite is also called quartz sand, silica quartz etc. Quartzite is the major raw materials to produce quartz or silica sand. Quartz crushing and grinding process are essential process in quartz crushing plant. In crushing quartz plant, we use jaw crusher, impact crusher, cone crusher, VSI crusher and mobile crusher as quartz crushing machines. Crushed quartzes are grinded into powder in grinding process using quartz powder plant. Ball mill, vertical mill, ultrafine mill are usually…
In crayfish the cardiac stomach has chitinous teeth in it. These are used for grinding and crushing food. The pyloric stomach is used for food digestion. The cardiac stomach is closer to the mouth of the crayfish. This makes sense because the food has to be crushed to make digestion easier. You body does the same thing. You chew the food before your stomach starts to digest it.
Teeth are very important in the digestion because they crush the food. the makes the food smaller in size, so it would be easy for tongue to mix those smaller pieces instead of larger ones. And this crushing or chewing also results in increasing the surface area of food that digested juice can act on, i.e the salivary amylase.
To find and catch their food, platypuses must make several hundred dives a day in order to catch enough food. They use the fine, sensitive electroreceptors on their bills, which detect the tiny electrical impulses made by underwater creatures which live on the creekbed or riverbed. After locating their prey, they dig up the mud with their bill to grasp them, crushing the creatures between grinding plates in their bills.
