Answer: for #2 you should put: The difference between food , bolus and chyme is Food is what you consume to go into the digestive system. Bolus is a small rounded mass of a substance of chewed food before you swallow the food. Chyme is a semi-fluid pulp that is in the stomach that is mostly made of partly digested food and the liquids of the gastrointestinal tract. The similarities that they have are that they all help the process for when your body is breaking down the food you are consuming.
For #3 you should put : The process of the digestive system is, When you first put the food into your mouth ,You obviously chew to break down the food but also your saliva helps you to break down the food before you swallow too. When the food is swallowed it goes through your throat and from there the food travels to the esophagus AKA the swallowing tube. The esophagus is a muscular tube traveling from the pharynx to the stomach. With a series of contractions, called peristalsis, and then the esophagus delivers food to the stomach. Just before the connection to the stomach is made, there is a "zone of high pressure," called the lower esophageal sphincter; this is meant to keep food from passing backwards going into the esophagus. The stomach is a sac-like organ with strong muscular walls. In conclusion to holding the food, it's also a mixer and grinder. The stomach produces acid and powerful enzymes that continue the process of breaking down the food. The small intestine is made up of three segments, the duodenum, jejunum, and ileum, the small intestine is a long tube very loosely coiled in the abdomen. The small intestine continues the process of breaking down food by using enzymes released by the pancreas and bile from the liver.
For #4 you should put: If the Salivary glands were to be damaged, it would make chewing and swallowing very difficult for you cause your mouth would be dry and you would also have an increase risk of tooth loss and and infections and decay in the mouth.
